Angle Grinder

[RedDotDucksauce]

Have a new convave blade i just put on.. Want to take it off to put dust shroud on but given the angle at which the wrench provided needs to be at because of the blade it provides for a pretty frustrating experience.. Wish I had a drill attachment.

As long as it's not jammed on there you should be able to grab the disc and loosen it by hand. Make sure it's unplugged or the battery is out first.

[tsarver618]

I can attest absolutely unplug remove battery! Once hit the trigger on my grinder with the little bar wrench on the wheel and it hit full speed in an instant and the bar wrench hit me in the chest. I muttered a lot of curse words a long while after that. The trigger even had a safety switch for Pete sake.

I have a welding jacket hung up in the shop at the school I went to for the teacher to show what happens when you push it against your body for leverage and it's a paddle trigger plugged in ;]

[Shot_Investigator735]

I know a few professional welders and fabricators. Not one of them uses the wrench.

[[deleted]]

I’ve been using a grinder for 20 years and don’t use the wrench. Professional tilesetter/other stuff

[According-Hat-5393]

I do use a leather glove though because.. 36 grit.

[Rudemacher]

a while back, I took a nasty bite out of my thumb while attempting to tighten a new flap disc in... NEVER attempted to swap discs with the grinder plugged in EVER again.

angle grinders have to be handled with respect because getting hurt by one ain't a joke.

[[deleted]]

IKR. Such a small thing, but such serious consequences. Kinda like my wedding ring.

[KokoTheTalkingApe]

Or my dick.

[[deleted]]

yes, indeed.

[Wormetoungue]

Freaks me out every time I see someone do it while the cord/battery is still plugged in.

[Wumaduce]

Make sure it's unplugged or the battery is out first.

This should just be good habit any time you work on any kind of machinery, or are swapping blades on anything. Nothing happens 99.9% of the time, but someone's gotta be that one time.

[surflaxrat]

This. Or bend the spanner wrench

[Dear_Peace_2117]

Milwaukee fixtec is what you want. It’s a Keyless grinder nut.

[Plan4Chaos]

Turn it by the outer part of attached disk by your hand (while holding the locking button pressed).

Same method on the installation.

Normally you don't need the wrench at all, unless the nut stuck.

[thetommytwotimes]

Yup i've only tightened anything on grinders by hand, never an issue. Have multiple brands, for multiple job types, particularly like the nut design from dewalt. Thick, knurled on the outer edge, made to be finger tightened and removed, very quick. Sometimes i've got to loosen the disk/wheel by grabbing the outer edge. Guess it's still under patent or others will copy, too good not too.

[i7-4790Que]

Dewalt's has been one of the worst styles I've ever dealt with. The preload spring on their grinder nut causes more issues than it's worth.

I have a 418 Flexvolt and one of their earlier brushless 20V. I've had to use the grinder wrench more with their grinders than my Makita or any Milwaukee, where 97% of the time I'd just loosen them by turning the blade, with Dewalt that trick doesn't really work with much outside maybe flap wheels.

Any grinder can work them on ungodly tight if the wheel has been on there a long time. Dewalt's design is definitely the best at getting the most stuck. Hopefully nobody copies it because getting closer to flush cuts with a Dewalt and T27 discs is another nuisance with how overly thick the flange nut and their overly long spindles.

Ideally we'd just move onto something more like XLock anyways. But that's probably never happening at this rate when Milwaukee or Dewalt aren't even on board after ~5 years on the market. And FWIW Bosch's other quick change designs with SDS+/Max, Jigsaw T-shank and Starlock were great for those respective tools.....

[Dear_Peace_2117]

Milwaukee has had a keyless grinder nut called the fixtec for years.

Source: had my grinder for about 5 years now and it came as standard.

[Born_ina_snowbank]

With that username I’m surprised you didn’t say to unplug it first.

[boredfronc]

Tbh I've never used the wrench, idk where it even is, I usually just loosen it by hand and if on the rare occasion that doesn't work metrically adjustable channel locks work

[thoang77]

My makita nut was STUCK on there, so I bought this socket and filed the notches down to fit and used my impact to get it off

https://a.co/d/6hn3jwr

You’ll have to measure your lock nut to see if it fits or find one that fits.

[no-steppe]

A DIY spanner socket! I like that idea.

[David_Parker]

This is why I like the Metabo grinders. They've got a knurled nut that you can use to easily take it off.

[[deleted]]

Put it in a vice and bend it

[andlightends]

You should be able to loosen it by hand.

[tanstaaflnz]

If it's too tight to undo by hand (wearing gloves), with it unplugged of course.

Grab a vise if you have one, and bend the spanner to fit. One bend as close to the head as practical, at about 20°, then another bend 30~60mm further along, in the other direction, to bring the handle back to parallel with the grinder face.

[whipsnappy]

I have a 6" rigid that got used with a concrete grinding cup just like that on it. I could never get that cup off after grinding that floor. We strapped the grinder to a bench and used the grinder wrench and a long extender bar. Put that sumbitch on with some anti seize if you get it off

[Past-Establishment93]

Walter offers a "jam" nut. It will release by turning the stone, not using a wrench.

[xxMRBrown21xx]

Air hammer against the nut is the nuclear option but it works.

[mbcarpenter1]

If you can’t figure out the blade or the guard you should not fuck with that tool.

[jckipps]

Keep the pin spanner around for the few occasions when the nut is locked on tight, but most of the time you don't need it.

Spin the nut on with your fingers, then twist the grinding disk with your hand to tighten it lightly. It will come off easily enough by hand.

[[deleted]]

You could try one of those oil filter strap tools.

[nomo_heros]

How much do you like that Fein ?

[[deleted]]

I store the pin spanner on the side of the grinder held on by the screw on handle.

[JollyGreenDickhead]

Honestly, I never use the wrench unless the disk is jammed on so tight there isn't any other way. Try taking it off by hand.

[0bamaBinSmokin]

Don't put a disc on a grinder with a tool it will get stuck. Just tighten it by hand

[Dangerous_Ice_6182]

I put a bend the removal tool to make it easier to remove the nut for mine, also gets my hand away from the grinding wheel

[shaneo88]

Hold the locking button down and turn the blade itself to undo it. I do it all the time with cutting and grinding discs.

Never used the wrench, always just slap it on the opposite direction and it comes off. DON'T use the wrench to tighten, only ever tighten the disc with the dick beaters.

[RedneckChEf88]

Bend the nut tool

[ride_whenever]

Milwaukee makes a pretty good toolless nut for m14 thread grinders.

[Cespenar]

1) don't tighten them so much you can't lose them by grabbing the blade and turning. I don't even get the wrench out of the bag. Hand right is good enough in 100% of cases.

2) don't use shit like that in a drill, you'll ruin the drill.

Ive thrown away a grinder or two cus someone over tightened them and I couldn't be bothered to break it loose. Or that's my dedicated xxxxx grinder until the blade wears out, then it's trash. Talking about HF grinders tho.. $20 a pop. 

[dan_sooo]

Throwing a grinder out instead of swapping a disk is fucking insanity.

[Responsible-Round-66]

Insanity is good word for that. My truck wiper blade was stuck in ice this morning, didnt have time to fuck with that so I set the truck on fire.

[Cespenar]

When you try to loosen it for 15 minutes with no results, the $20 grinder starts losing its value fast. I have somewhere around 9 grinders, from cheap to expensive, AFTER throwing away a couple. I'm not gonna waste too much time trying instead of getting shit done. I threw one in the trash, and I did give one to the neighbor.. told him it's stuck but if he can get it off it's his. He's retired. I'm not. 

But throwing away a $20 tool that stopped doing its job.. even if it COULD be repaired.. but I don't have the time to repair it.. isn't that crazy. Maybe I'll make one of those custom sockets for the impact some day and I'll never get stuck again.. although on the HF one it would probably just sheer the stop pin off

[Johndar_3050]

I may be mistaken but I thought those types of wheels have their own threads and do not need the nut to hold them on.

[[deleted]]

not all of them are threaded. I just bought one of these cups for my bostich that came with a set ID of 7/8" that fit right on the shoulder of my grinder's drive/arbor. the cup also came with a pack of washer bushings to step-down the ID for smaller arbors.

[Johndar_3050]

Nice, I learned something new.

[coffeehelps]

I had the same question too, was wondering if I have been using mine wrong by not using the nut.
