The best cheap angle grinder? Black and Decker BDEG400 teardown and review

[@cristian82h]

I had a lot of old pipes and rebar to cut up and from what I read kzbin.infoUgkxPDBfLu68o58Aw85O_J-zIFfjJARBhp-3 this would be the tool for the job. Since I had never used one, I watched a couple of youtube videos and I'm so glad I did. Some really good safety tips, which I followed, and this tool did a splendid job. One good thing to know is the weight of the tool puts just about the right amount of pressure on the metal I was cutting, so I didn't have to use a lot of pressure, which is more likely to jam the tool. It made fast work of my job.

[@AZ_sunshine]

THANKS for the outstanding review and tear-down. You put a lot of thought and time into helping others and it is appreciated so much.

[@trekzilladmc]

I got mine 2 years ago for Christmas and it's definitely worth the price. I've used it to grind, sharpen mower blades, cut steel pipe, wire wheel, and remove paint. It's comfortable and durable.

[@elderfarms]

My ex girlfriend bought this for me at WALMART over 3 years ago. I didn’t think I’d like it but.... I absolutely love it.

[@NeoAH90]

Just put some quality grease in the gearbox for lasts.

[@JamesSmith-lt5zz]

Ya the hypertough is the exact make as this. The only difference is hypertough has a 8 amp rated switch instead of 10 but the parts are interchange black and Decker makes all the hypertough tools. If you need brushes for Walmarts grinder you look up this bd grinder

[@lugwrench9832]

Keep the girlfriend, for sure.

[@larrycroft470]

I bought this grinder based on this excellent review and have been very satisfied. Thank you for taking time to make this.

[@982Nighthawk1337]

Very good and informative video. I would like to see you take apart a Bauer or the hyper tough (Walmart brand) angle grinder if you should happen to get your hands on one. Or any other hyper tough tool for that matter. Thanks for the great content.

[@jeremybennett5547]

I've had the grinder for 5 years now, not one problem and it has very well paid for itself. It gets my recommendation

[@RR-gw2uj]

People talk smack about B&D a lot, but they still are a great, affordable tool brand. My first jigsaw was a B&D, is over 7 yrs old and I still use it for everything today, and I think I only paid around $35.00 bucks for it. Seven+ years of use for $35.00 is outstanding in my opinion.

[@scrapheaper]

Thanks a bunch for this work ! searching replacement for a vintage bosch 1347, this was pbly the most valuable/informative surgical teardown / test i ever watched. youre a referential level !

[@Vgk36]

I use the black and decker everyday. I'm a believer in this unit. I'm working part time at a fab shop and I grind for 2 hours at a time 5 days a week

[@PatrickCrossfire.]

Very nice video. I actually use one of these. I paid $31.00 in 2018 for it and used it a lot. The other day I pushed it a little too hard and overheated the windings a little but it still runs. Very good grinder for very little money.

[@gosonegr]

I have the older model, and yes, it's amazing, 7 years and works no flaws (even tho I cut the cable with the grinder), for 25 euros... you can't beat it

[@vincenttitone8776]

Nice video. Have you considered getting together with Project Farm? You two would make a good team

[@dcrickerson7611]

Your video's are top notch! Very informative, thank you for making them. For me I think the Black and Decker is worth the extra money.

[@Bence507]

I had apart a 30 year old makita grinder. It had a rough life, all the bearings were bad, the pinion broke. In the head it also had a bronze bushing, and it was mint. Tight, no wear at all. In my opinion a good quality bronze bushing beats a cheap roller bearing, I can imagine the more moving parts wear out quicker. Fixed up and using it of course :)

[@ToolTeardowns]

That's an interesting observation. I will say the more expensive grinders I've taken apart also had needle bearings instead of bushings.

[@JoeHenry734]

I'd like to see you tear down the red Harbor Freight angle grinder (runs about $16-$20); I've been told it's much better than the $10 one. I'd be curious to see what differences are inside.

[@danceswithaardvarks3284]

What a great channel. I found it researching whether the Black and Decker bottom end would fit on my old burned out Freud biscuit jointer. This video has given me the confidence to give it a go. Worse case is a cheap backup angle grinder.

[@BL-yj2wp]

I just bought a "Parkside" grinder from Lidl (German supermarket chain). 125mm (5 inch) rat tail style, 1200W, quick adjust guard and speed control for 22.99€ after tax (that would be 21,13$ before tax). I don´t know if Lidl sells powertools in their US stores. I might take it apart and have a look, for the power it´s definitely very cheap, about half the price of nameless grinders with similar specs- I does come with a three year warranty wich is nice. Feels good, PA6-GF30 for the housing, the flex has a thermal plastic jacket though. These videos are very inspirational. EDIT: The Black&Decker seems to be a good offering for 20$. For some small stuff around the house or multiples for specialty attachments it´s good to have around. For everyday and professional use something a little better would be more like it.

[@algo9136]

This video changed my opinion of the B&D brand.

[@melgross]

I’ve got Vessel drivers as well. It’s interesting to note that they developed the JIS bit standard. The set I have is different. The tips are designed to properly fit both JIS and Phillips. They do work very well. I see that the B&D has the same wrench for the wheel lock as the HF model. I recently bought that HF model. Normally, I use both 7 and 11 amp DeWalt grinders. But last year, Jody from Welding Tips & Tricks showed an adapter for Roloc disks, which I bought. $15, and a great idea. So I can use them on an angle grinder in addition to my handpiece on my Fordoms. Problem is that they’re really too big, heavy and powerful for these 2” disks. The HF is perfect for that purpose. Small, light, and far more powerful for that use. The only complaint I have about the HF tool is the switch, you should talk about switches. The paddle switches are far better than any slide switch on an angle grinder. The paddles let one use at least two, and usually, three fingers to hold it closed. The grip is natural, as it’s the same you use to hold the tool. The little flip safety works very well so that you forget you’re using it after a short time. The push switch uses one finger, usually the thumb. It’s spring loaded for safety. But that spring is hard, and your thumb gets tired after a short while. Your hand also slips towards the rear of the tool, since you’re pushing the switch forwards. I don’t know how that BD switch feels. But the one from the HF is surprisingly tough to keep closed. I wouldn’t expect to see a paddle switch on a cheap tool, as they do cost more though. What does the BD weigh? One major reason I bought the HF for the Roloc was it weighs so little. But, this is the only grinder I took the guard off of. You don’t need it with Roloc disks, and the disk sticks out 4 inches anyway. That allows it to reach spots that you can only dream of with the 4.5” disks. You should try it.

[@DFNUVS]

This B&D angle grinder weighs 4.5 pounds.

[@Lmolina90]

Glad you found Vessel screwdrivers. I bought one on a whim a year ago after encountering some JIS screws and use it almost every day. Their drivers work great with regular Phillips drives in my experience as well.

[@DFNUVS]

I didn’t like the Black & Decker model only because it was not cordless. I returned it and wound up repurchasing it because it can’t be beat for the price and performance. I’m still shopping for a cordless model of grinder, but still is very sufficient given that it lacks portability. B&D has outclassed the major manufactures with this tool. Thanks for such an in-depth examination and analysis. 👌💪🏽✅

[@836dmar]

DFN UNIVERSE I bought a Mikita cordless. I needed to wire wheel the mortar up on the chimney and didn’t want to bother with the danger of heavy extension cords. Awesome power for a cordless but they are not cheap and are all battery hogs. It’s tough to beat corded tools and even good ones are dirt cheap by comparison. I would never buy a cheap cordless grinder as even the pro brands have short battery life and those companies do a lot of work to get reasonable torque from them. The likelihood of making one on the cheap is nil. Drills are about the only tool that has progressed to a near equal state with corded drills(if you pay enough). I bought a cheap HF drill just to leave out in a hangar. Battery charger wouldn’t work. More expensive one wouldn’t work either. Friends had some that charged and I used it. Worked minimally for $20 but was soon tossed. Bought a $$ Mikita drill and now leave the cheap Porter Cable out there. It has enough power and life but the e-brake loosens the chuck when it stops. Just saying there are good reasons to buy great tools. BTW, I use my cheap corded grinders instead of the cordless just to save the battery cycles so these are still relevant.

[@AlexGiron-zg7dt]

This is an awesome video. Explains so many questions. However it’s been asked a few times, but don’t see an answer is there a part number for the brushes for the BD grinder?

[@RobertSiwik1968]

New subscriber! I really like your attention to detail. I'm gonna pick up the B&D. I burned up my cheap harbor freight already and bought a nice dewalt. But I like having a spare cheapy! Lol

[@laynesamba]

The cheapo Black and Decker tools are pretty decent. I got an 8volt impact on clearance and it does 70% of the work my bulky dewalt 18volt used to do

[@viperstrike3827]

i have watched you take apart 4 grinders and i must say that the makita 9557nb that i took apart has the best brush holders and the biggest brushes

[@nonuabisnus]

Last year at my local Walmart I found one of these grinders for $15 and a Bostitch 3/8 inch plug in drill for $20. I got them both, the grinder came with 3 discs which come in handy for sharpening lawn mower blades, the drill has enough torque to rip the heads off of 3/8 inch thick lag screws if you push it that hard by accident, whoops!

[@Starman-yt8lj]

Thanks for the in-depth tool review. Just ordered the B&D on Amazon. 👍🏻

[@markfannin3975]

[@andrews5926]

I love my 10$ grinder had it for 3 years an no problem other than the handle snaping

[@springer-qb4dv]

original handle is too short and flimsy. I made my own handle using 5" bolt I bought from home depot.

[@danoesq2]

I've got the slightly improved Drill Master for ten bucks (with a coupon) and it's hanging after hours of use. It has better internal parts then the previous version and will hang if you don't stress the motor and overheat it.

[@ToolTeardowns]

Are you referencing this other video I made or something else? The grinder I compared to the Black and Decker was the better of the two. kzbin.info/www/bejne/jGPLhXdqptB_n8U

[@springer-qb4dv]

cheap HF grinder won't last long if you really push it.

[@felixf5211]

This grinder looks pretty good for the money. I'm actually looking to add another grinder to the shop. The B&D is ~$30. Makita's entry level grinder is only $10 more. HFT's Hercules grinder can be had for ~35. I've had one for over a year and it performs very well. Surprisingly so. Hard to seriously consider the B&D, given the competition.

[@lordrichard8184]

I think the black and decker vs the harbor freight paddle grinder would be interesting to see. As they’re both around $25. And better then the $10 grinder. Great info and cool channel!!

[@Nothingtoya]

Holy crap, KZbin hasnt been notifying me of your videos. I thought you hadnt put anything out for months.

Would you recommend the B&D for light duty like sanding/grinding of a lawnmoer deck and sharpening of lawnmower blades?

[@ronsonroberts2207]

What kind of brushes does the Black decker grinder use?

[@markallen4001]

Never heard of twisting to line the switch on top. Very good idea. I am left handed and this would help a lot. Can you do that to the Makita grinders? Thanks.

[@ToolTeardowns]

I don't know about Makita. You can do it with a lot of grinders, but not all.

[@BlownF150]

The Porter-cable PECG011 4.5" angle grinders are a rebadge of this grinder, Lowes has had the P-C grinders on sale for $16. Only problem is that finding replacement carbon brushes is not easy, and these brushes go bad almost instantly if these grinders get into a stalled situation.

[@mohammedtoqir6506]

I got the same type of black & decker angle grinder and the first time i used it i tried cutting a concrete fence post and 30 seconds in to using it , it stopped can you help and tell me what i might have broken or burnt in side the grinder I don’t want to throw it away as it brand new only used once for 30 seconds. Any suggestions would be appreciated.

[@vintageradiobuff5939]

I just acquired one of these, so found this very interesting and informative. I have a question... what type of cutting wheel were you using? was it a Type 1 or Type 27? (couldn't tell from the video). The reason I ask is that the manual says to NEVER use a Type 1 disc, and I have a bunch of them and no Type 7 cut off wheels.

[@DFNUVS]

This grinder uses a type 27 disc. At 11,000 RPMs, the wrong disc could potentially become a very hazardous projectile. I’ve put a fabric cutter hexagonal blade on mine to add even greater risk. Ideally, the disc is sandwiched between the two flanges and has not moved yet. However, I have only used it once with that flat disc and I’m scared to use it again. 😅. Hope this helps...

[@mjmcomputers]

Thanks for the video. Lowe’s had the hitachi grinder a few months ago for $20 and I should have bought it. Been looking for a cheap grinder to leave a flap disc on. I get tired of switching discs all the tine. I may need to buy this Black and Decker as the Hitachi has gone up to $40.

[@garyrichards407]

I bought one for the same reason. I have used it for a year stripping automotive paint mostly and it still works great.

[@DFNUVS]

Amazon has the B&D for $23 for a limited time.

[@crazyhorseracing6130]

Thanks for all the cool videos. Can you do a tear down on a WEN 4.5" angle grinder?? Thank you!

[@UnoAluminio]

Why DIY tools (like B&D) heat up fast and pro tools (Makita, Bosch) barely heat up? Does the motor run hotter or has a poor cooling system?

[@What_Other_Hobbies]

BDEG400 is 6.5AMP now. i guess Black+Decker updated the internal components. Worth getting another one?

[@lipevolcom2]

I have one but didn't used that much because I got a Makita for Just twice as much I payed for the BD. But I use the Makita as 220v in 110v so I got low rpm. Same thing with my new big Makita ga7020. Running on low voltage to get low rpm so I can use as a sander as well and not burn the wood. If I need high rpm I'll always have the BackeDecker on standby

[@Questchaun]

I bought a Hazzard Fraught drill once. Let the smoke out while plugging it in. And burned the brushes out of it when drilling a 1/2 bit into a 2*4. You get what ya pay for.

[@bnasty267]

Normally, I'm a big champion for the value HF tools offer, but that guard is a dealbreaker. Paying the $10 extra for a guard that can be easily adjusted is worth it to save you time and more importantly, stop you from wanting to remove it completely. Just google for angle grinder accidents to see what happens when a cut off wheel spinning at tens of thousands of RPMs decides to come apart. That $10 guard could save you thousands in hospital bills.

[@ToolTeardowns]

Yeah, the guard is a really big improvement.

[@vwmullen]

I wonder how it compares to Harbor Freight's Chicago Electric grinder that's in the same price class?

[@jacobmckee5862]

Yes, I would and do use warranties for budget tools.

[@Jim-ie6uf]

Great comparo, the HF probably cost 60 cents, to make the the B/D probably 85 cents. I have a Porter Cable grinder, got it on Amazon for $60.00 or so. But just like the others, it slings grease off the gears and flings to the sides of the case. It did, however, come with a cutting and a grinding guard.

[@svdelhi]

i replace my old school power tool cords with the orange cord from hardware store off the bulk reel.i get some really good old made in usa electric power tools and usually because the cords are brittle and cracked exposing bare copper wires. the electric drills i retrofit the jacobs chuck with a key to a cordless keyless 3/8 chuck from a dinosaur cordless drill or a dinosaur cordless drill from a garage sale for a dollar.i can get old aluminum housing power tools for 1-5 dollars this way. with a little sweat equity i get a power tool that will outlast me. on drills i usually remove all the old grease and repack with synthetic grease.i lubricate the armature bushings and scotchbrite the commutator . i can dedicate drills with wire wheels and flapdiscs and just grab and go. most have the locking trigger. i also spray the switches.these old drills will get so warm you need to wear a glove but they always work and dependable after going through them.

[@JamesSmith-lt5zz]

How come no one post videos of the hypertough grinder tear down. Black and Decker makes hypertough. The brushes from this grinder fit it. The hypertough switch is rated at 8 amps even though the motor is rated for 8. There's halfa dozen grinders with the same basic shape and anywhere from 5.5-8 amps. I would like to see a amp draw on these cheap grinders. Since the switch is half decent. Brushes are cheap like 5 sets for $12

[@JamesSmith-lt5zz]

Motor for 6amps* not 8 I think it's draws a little more then 6. My 8 amp Ridgid doesn't have really much more power then it. Only a tiny bit.

[@JamesSmith-lt5zz]

2nd edit. The hypertough takes the brushes from the 6.5 amp grinder sold right next to the hyper tough. For a cheap couple grinders to have Walmart has them on sale for $16 right now. I keep one every vehicle there great to use and if someone wants to borrow it it's not a big deal they break or trash it. Or someone needs one at work if a tool goes down. I've put them through hell. All day grinding with flap disc. They can go replace it for $20. My favorites are my dwe402, and my 7in ridgid 15 amp.. what I always do is open up the gear case. Before I start it. And remove the cheap grease. And use the Chevron red lithium grease. And once ive ran it a month or so I do it again except I open the sealed bearinga and get the red grease inside them. Never had a bearing failure. The cheap grinders don't come with much grease and crappy grease they want you to buy more tools. That redgrease handles 10000 psi of the pump trucks at work. This is child's play for it. Never lost a bearing in any tools I've done this to from new. Drills, dremel, sanders.

if anybody buys the orange recip saw from HF i found out when it sits for months without use it is best to start it with no load at full speed till it picks up speed and runs smooth before putting it to work. the commutator gets corrosion and has to be worn off in a no load situation. i always remove and replace the grease in HF power tools first thing when new. the grease they use is bad right out of the box. if you use the recip saw when its running intermittent it will heat up and overheat letting the magic smoke out

Well, it´s of course made in china, and for a budget tool like this they probably used the screws they had lying around in a dusty warehouse. The manufacturing cost would be 10-20% of the sales price. And if you want to build a grinder for 4$ ...
