DeWalt dcht820 hedge trimmer 20v review
With our DeWalt tool unboxing and review underway, the only downside I see on this DeWalt cordless hedge trimmer is the trigger button does not have a lock-on feature, so this dcht820b dewalt cordless hedge trimmer only has a momentary on/off trigger. This means you have to hold the trigger button down all the time to operate this dewalt dcht820b cordless hedge trimmer. This cordless trimmer has 1" spacing btweent peaks of the blades, and 3/4" hole cut diameter, so the maximum branch cut size of this DeWalt DCHT820B cordless trimmer is 3/4".

[@niallmacauley430]

HI again Jeff. Have had the DE Walt hedge trimmer for 3 months now and it is excellent! What you guys call a " yard " we in Ireland call a garden and mine is about 0.75 acres surrounded by hedging. The DeWalt makes easy work of keeping it in shape! I also bought the WORX snipper tool from Amazon US ( not available for some reason on European sites! ) It is also fantastic! ( In my opinion any WORX stuff I have is brilliant! ) Makes short work of carving up cardboard packaging and makes more room in recycle trash bin . Thanks for the help! Keep it going and stay safe in this strange World!

[@jeffostroff]

We are today also filming our tool review for the small Warrior electric cutting tool to compare against the Works 4v electric cutting tool, great for cardboard cutting.

[@grdkgameplays1496]

Thanks for the great test, keep it up !

[@jeffostroff]

I'm glad you like it and thanks for watching

[@dadathome274]

Zip ties fix the non locking trigger. You should mention that its always best to cut the way you did, from the bottom up. Also, before I put the sheath back on, I take a small whisk broom and sweep all the cuttings off the blades and just let it sit in the sun for a while to let the moisture dry. I give it a light shot of WD 40 on the blades, run it for a few seconds, wipe it down, and go have a beer.

[@jeffostroff]

Good idea on the moisture. Instructions also states: 1. After use, carefully clean the blades with a resin solvent. 2. After cleaning, apply a light film of lubrication to the exposed blade. Now they don't specify which lubricant to use, so I'm assuming a 3 in one oil maybe would be best. I don't agree with WD40, because WD-40 isn't actually a true lubricant like we expect a lub to be. WD stands for "water displacing" and its use is as a solvent or rust dissolver. I imagine it would be OK as the cleaning part of the maintenance steps here because it has the Stoddard solvent with mineral spirits. Then follow up with 3 in one oil.

Hi Jeff, I have this DeWalt 20v hedge trimmer and it's great. It's been out for a while and hope dewalt can make a brushless version. You're also right about the battery. You really only need the 5.0ah. I do use the new 6.0ah battery a few times and it's not to bad. Anything smaller than a 5.0ah doesn't run as great. Thanks for the video.

[@jeffostroff]

Thanks for watching the video yes I was hoping to find a purseless version also but I think we're it's so good on the battery already they may not bother with one.

[@uthermaceanruig5098]

I'm not usually up this late on Sunday but nice video Jeff lol I'm up mostly because I'm in pain as I accidentally twisted my foot after tripping over the metal peice on the side of the decking of the person's place we are working for but this is cool. I'm going to try to get some sleep though, goodnight Jeff lol

[@jeffostroff]

Awesome! It was a nightmare getting this video to premiere, for 2 nights in a row, KZbin's joke of a premiering system did a countdown, said it was going to start in 60 seconds, then never started. I had to delete the video and re-upload it for 3 hours upload time, and no premiere, just a normal upload. Better late than never. Sometimes KZbin really sucks, yet they keep patting themselves on the back how great their platform is, they keep rolling out new features, but fail to fix what's broke with existing features.

[@lanalovely1538]

@@jeffostroff oh wow, I'm so sorry jeff but at least you got it uploaded. KZbin can be kinda buggy sometimes I will admit that, I'm not a huge KZbinr like you so I don't upload all the time at all because I have nothing to upload really but when I do sometimes it takes FOREVER to upload or it will supposedly upload twice or something lol. That's happening with the same thing on Facebook/messenger they keep adding "new updates but they don't feel new both apps are literally the same and it's frustrating me because I want a Facebook dark mode and new features for once.

First time watching on of your vids and loved your content! My wife and I just moved into a new house and are wanting some nice hedges. We live in zone 8 and I was wondering what breed of hedges you have.

[@jeffostroff]

I believe those were Surinam cherry. I emmoved them as they got too tall last year and replaced with Simpson's Stopper hedge

[@jeffostroff]

Thank you 👍 Brian!

[@brianalvarado7668]

I truly find every detail useful 👍🏻

[@garybartek]

nice video. Q. Can the blades be sharpened by self or outside hardware store?

[@jeffostroff]

Here is the only thing the manual says about sharpening blades: The cutting blades are made from high quality, hardened steel and with normal usage, they will not require FIG. 12 resharpening. However, if you accidentally hit a wire fence (Fig. 12), stones, glass, or other hard objects, you may put a nick in the blade. There is no need to remove this nick as long as it does not interfere with the movement of the blade. If it does interfere, remove the battery and use a fine toothed file or sharpening stone to remove the nick.

[@kunjiklub]

Thanks. I just purchased the bare tool from Home Depot. Mine didn't come with the sheath though so I'll be contacting Dewalt to see if they can send one out to me.

[@jeffostroff]

You are the 2nd person who mentioned to me that they did not receive that plastic sheath on their tool.

[@CovChannel]

@@jeffostroff I just got mine from Amazon. No sheath! The manual still says it should have one though.

[@kunjiklub]

@@CovChannel I went on the dewalt.com website and created an inquiry case for this. I'll give my updates on this here

[@jeffostroff]

@@CovChannel Can't figure out why a handful of people are not getting that sheath

[@CovChannel]

@@kunjiklub It seems like it is just a roll of the dice. The Amazon reviews have people praising the sturdiness of the sheath they received, and then people who didn't receive one at all. The part number is 90629314, and it can be purchased from partswarehouse.com for less than 10 dollars. At least there is an option if DeWalt doesn't come through.

[@captainskippy6622]

Just bought this because I have lots of Dewalt tools and batteries. I and am considering getting that flex volt 60 battery you showed for extended run time for this and my pole saw. Will a regular 20 volt charger charge the 60?

[@jeffostroff]

They will if the owners manual shows that they are capable

[@johnbuck2227]

Is it important to use 3 in 1 oil at the end of each use to lubricate the blade? I didn’t see any advice to maintain the DeWalt after each use. Thank you!

[@jeffostroff]

The instructions state "Prevent the blades from rusting by applying a film of light machine oil after cleaning."

[@JoanFCarson]

I watched your video and bought the trimmer but they never sent the protective sheath for it, I was wondering if you knew where I could find one, I looked every where that I could think of and can't find one. Any help you could give me would be greatly appreciated. Thanks for your great video.

[@jeffostroff]

I have heard from a few people who did not get that protective sheath either I would call the walls and tell them it never came. If they give you any grief you can file a complaint with the Consumer Product Safety Commission

[@Clark.Griswold]

Hi Jeff...I bought the same hedge trimmer and absolutely love it. The manual suggests cleaning the blades with a resin solvent after each use, followed by applying a light film of lubricant to the exposed blades. I want to make sure I'm using the correct resin solvent/lubricant so not to damage it, and to keep this baby running for years. I wrote to Dewalt but they just gave me a canned, "any will do" response. Not much help. I've asked sales people at both Home Depot and Lowe's and they can never give me a definitive answer. Isn't there a particular brand of resin solvent and/or lubricant everyone uses on their power tools? I also just purchased a Dewalt chainsaw and was hoping I could use the same brands on that one as well. Any suggestions? Thank you.

[@jeffostroff]

Funny you should ask I don't know yet, I am in the same boat as you I was going to start researching on KZbin to see if some of these other guys who work with these tools day in and day out have any idea or maybe just start Googling hedge trimmer solvent or something like that

[@russellkulp2124]

I have always used WD, cleans blades and no rust.

[@mjayeh]

Great minds think alike! That cutting tool I bought at Lowes 5 years ago, they don't make it anymore, so I bought a newer one from Worx that I just got in a few weeks ago, I plan to have the tool review comparing it to my older one uploaded in a couple of weeks.

[@jeffostroff]

I'm not sure but I'll guess on and in would think that the 18 voters may be the older one and the new 1 is the 20 volt, more in line with Flexvolt batteries.

18v is the nominal voltage, 20v is the no load voltage. These tools run at 18v under load.

[@albertsanchez8007]

The spacing between the teeth is actually 5/8” inch. Measure it correctly.

[@jeffostroff]

At 5:50 the video clearly shows the space from center of one tooth to the center of the next tooth has one inch. I don't know where you got your number from but it's completely 100% wrong. They advertise that this hedge trimmer can chop through three quarter-inch-sized branches. In order to do that by default it has to be bigger than the five eights that you are claiming. maybe you should measure it correctly

[@albertsanchez8007]

​@@jeffostroff You actually believe vendor advertising? Watch this video, the guy measures the cutting width via a caliper, and it's about 5/8". Moreover, the trimmer cannot cut (or even engage to cut) a 3/4" dowel because the space between the teeth isn't wide enough. kzbin.info/www/bejne/oXrPg5aoopaFfLs
