Harbor Freight Chief Industrial Mini Die Grinder Test & Review

[@FisherCatProductions]

Appreciate the video. I've had mine for about 2 years and today it froze up. Disassembled, cleaned, generous application of break-free lube and it's up and running. Not sure what happened--I may have forgotten to give it a shot of lube before I put it away last time. This video definitely saved me some time pulling it apart! Thanks. BTW, for anyone thinking of buying one of these, it is an amazing grinder. Easy to get into small areas. Does not bog down. Easy to service.

When you double the diameter, you double the load. The formula for circumference is PI*D, so PI is constant. Great video, thanks for making it. You always do excellent tool videos.

I work on classic cars and bought a Chief angle and straight die grinder a year and half ago to start at my new job at a restoration shop. I grind welds constantly everyday and never broke the plastic ring. I am very happy with the quality of them for the price. I bought two more pairs to reduce the stress I put on them and so I don't need to change applications all the time. The original angle grinder is getting loose around the head of the tool so I have to tighten it back up every once in a while but it still works great. For 40 bucks it will pay for its self in a day of work, Like I said, I have grinded welds non-stop with these for a year and a half straight. I also have the Harbor freight insurance where I believe they will replace the tool for you if it craps out. Buy them, Oil them every day before use and they will last fairly long. They grind very well too.

I got the right angle model and the power is amazing for the price. Massive improvement over the $12 variety that bogs down to zero RPM when putting any kind of pressure on it. When using it, an internal threaded retainer ring kept spinning out. I secured it with Loktite and snap ring pliers and it hasn't spun out since. I also got the air hammer and the power is pretty amazing for the price. I doubt the build quality of this stuff is suited for daily use but for the hobby mechanic who uses the tools maybe 10 times a year (like myself) you're getting the power you need without blowing your wallet to hell.

[@corthirteenth94]

Used a Chief Air Hammer in my shop professionally for over a year and it's been fine. I'm still waiting for my 1/3 of the price HFT "Premium" brands to fail from daily use.

[@corthirteenth94]

Always appreciate your tear downs!

[@moparnut6286]

I used this today with a cutoff wheel attachment to cut off some sway bar tabs off of some lower control arms, worked very well it's compact size let me get in and cut at welds easily and didn't bog down doing it.

[@Ziji-LetYourSoulShine]

What sort of air compressor do you have? I have a big air compressor from harbor freight that is rated at 4 cfm @ 90. This tool says air consumption is 2.9 cfm @ 90, but it bogs down after a few seconds and will not do anything. Am I doing something wrong, or is the air compressor just no good for air tools? The impact wrench I have does the same thing

[@moparnut6286]

@@Ziji-LetYourSoulShine Well I'd say you don't have enough air capacity...... I run a harbor freight 60 gal two stage 15.7 CFM do they sell those were you are? I think it's expensive in your area.

[@Sxvaqe-_-]

@@moparnut6286 lucky I got my 8 gallon tank hopefully I can tackle rocker panels with it ,btw what do you do with ur 60 gal ?

[@mastermeme]

Working an industrial shipyard being tiny 5'1 they put me in the smallest enclosed restricted tight spots pretty regularly, I use this die grinder when I'm welding it works ok constantly needs daily lubrication but that goes with pretty much all pneumatic tools I would give it a 7 out of 10 reliability sometimes the die Chuck gets just grit that's just from operation

[@tammyward5025]

How do you loosen the collar to add the attachment?

[@CatusMaximus]

It should have come with a couple of wrenches

[@kunalindia3698]

That's a very good indepth look at that tool

[@user-tk5bz1ss2z]

where can I buy chuck for air die grinder 1/4?

[@hardlyb]

Like the reviews. I've basically stopped using air tools since cordless ones got so powerful. I kind of miss the air tools, but not enough to get a big compressor. Just a small nit: double the diameter you also double the circumference. It's true the circumference is pi times the diameter, but that's true for the smaller circle, too.

[@precesionnoreaster1507]

What makes you miss them

Great video! Thank you. I have a 1/2" impact that needs new vanes, do you know where I could find replacement vanes from. It is a Harbor Freight impact. Thank you!

My Florida Pneumatic still works fine after 32 years of occasionally porting heads and manifolds.

[@paulrevere-e6y]

the chucks (collet?) keep getting stuck in the spindle when I change them out

[@steveheavener4932]

Good review. Do they offer that in a 90?degree?

[@cbmech2563]

They don't show it in the catalog , but they have it in central pneumatic . I've had mine for 6 years cleaning gasket surfaces

[@rjstiles80]

They do now

[@phillipvansickle4220]

Just bought the 90 degree one...very pleased with it so far.

[@mikeburton1703]

i would want to use this tool with a cut-off wheel .....have yet to find one that doesn't bog down cutting off rust sections of fenders that have rusted out......snap-on even says their best will bog down ....i don't mind paying a price for a good one....i like the short version here but if anybody can tell me the "best ' i would love to hear about it.....thanks...

[@cosmoraptor3743]

Hazet ones is extremely good

[@tomtillman]

Are you using V-type fittings? Night and day vs m-type on my air wrench.

[@FisherCatProductions]

[@ronparker6489]

Well done vide, sir. It will be my next new toy, albeit this guy seems to be a little pricey, as you mentioned. But Merry/happy Christmas to me!

[@johnkordish3546]

This is a great air tool

[@garywelker8398]

Why would want your grinding material to be blowing around ? Thats NOT why it has FRONT EXHAUST.

[@larryborkstrom3580]

The berrings would cost more than replacing the tool

[@mohabatkhanmalak1161]

A lot of these low priced, China, Taiwan made tools and machines can be upgraded to a high standard. All that needs to be done is a tear down and then identifying areas of weak design, engineering and build. Replace these with proper parts and materials and you will have a quality machine. Watch on KZbin, how Keith Fenner modified a cheapo grinder that had vibration and the usual low build quality. He made it into a really top class machine, finely tuned machine.

[@Ace-zb5xr]

40 bucks is about 30 too much for any straight die grinder. That is the easiest tool to make. I have a ten dollar from the grocery store one that I have been using for 30 years, at times all day long. I would gladly pay $120 for a replacement from anywhere besides HF! Might even find a used Dotco for that price.

[@bohaggin5913]

Ignorance is bliss. Keep at it 👍

[@upsidedowndog1256]

@@bohaggin5913 Sure will. And keep using my &10 grocery store die grinder instead of buying ANYTHING at HF!

[@googlesucks100ballsandshaf6]

I don't understand the HF premium brands... Id go buy dewalt before id pay almost the same price for theirs..

[@farmerjim-fat-man-do]

Googlesucks100 Ballsandshafts I agree....HF is going to price themselves out of business if they drop the cheap line of tools for the only slightly better and way more expensive premium brands. I feel most people continue to patronize HF for their selection of cheap tools. If I need a tool for just a couple uses I go to HF. If I need a tool that will be reliable and last for years I buy a name brand tool. Cheap tools have been their core business moving away from that will cause me and I’m sure others to go elsewhere.

[@Mexicanmike87]

@@farmerjim-fat-man-do I don't think they're moving away they're just also trying to get more professional business, people have been really impressed by a lot of their more expensive brands such as the Hercules, Fortress, Doyle and Daytona line

[@Shabnation]

Don’t forget dewalt is a glorified black and decker at the end of the day ......

[@ZVPieGuy]

This die grinder costs $25, and if you use a 20% coupon that becomes $20. Good luck finding a dewalt for $20.

[@josemary2106]

[@rubenclark8017]

Not surprising, any pos.grinder will do that.

5 MAGA. I've been using an older Harbor Freight like that for over 6 years with absolutely no problem. Except that about 6 months after I bought it somebody borrowed it and "returned" it with a dent in the case that leaks air in use. Still working 😊
