Drill bit tool for grinding off an old chain?

[CC07 PEU]

Can anybody recommend a tool/bit that I can use with my drill that'd be ideal for grinding off an old chain? If so, can you post a link to the site where I can buy this please?

I ordered some replacement chain pin removers for my chain tool from a site called 2wheeljunkie but their ecommerce system is st meaning the address didn't go through properly and hence the required tool parts haven't arrived! I'm trying to follow this up with them at the moment but need a back up as I want to get the chain and sprockets replaced this weekend.

Sounds like you're after a little cutting disc that you'd use in a dremel, thing is dremels spin at a hell of a lot more rpms than a hand drill - not sure if it would work.

Yes, a Dremel was what I had in mind but since I don't have one, I thought a special drill bit would be the next best thing.

I used a whizzer to grind off an old chain.

It was suprisingly though and took ages. Remember to grind over the rear sprocket, not mid-chain.

Not that I've done that...

Surely someone local to you has a chain tool? Sounds a lot less messy / risky?

In the past when I've been without my trusty Angry Grinder I've resorted to a small tri square file that's lurks in the depths of my tool box.
Surprisingly easy, five mins of steady filing the riveted soft link as it is braced over the rear sprocket.

I'd go with the above... buy yourself a decent file. Use the rear sprocket to support the chain and the job will take next to no time... with the added advantage that you'll have a handy tool that you can use on brand new knee sliders etc.

If you must use a power tool, cheap angle grinders can be picked up for relatively little from those discount places and will last years for these sort of jobs.

You can get angle grinder type discs that go on drills. But I'd be tempted to try a hacksaw with a reasonable blade (ie not the Chinese steel blade which comes with a £3 hacksaw).

You can use a standard die grinder bit in a power drill (mains powered drill, not battery) though progress will be a little slow as they don't spin as fast as a proper die grinder.

Seriously guys, what's wrong with a chain tool?

I have that exact one and it takes about 30 seconds to break a chain with no mess or sparks or st like that.

find the soft link rivets in the chain rotate this so it is on the rear sprocket then get a HSS/cobalt drill bit that is bigger than the rivets and drill the head off the rivet then the link will push out use this vid as a guide http://youtu.be/Xob4hNPbypw?list=UUOXDrrwQRZqOQ3iU... (although this is a bolt but same principle)

I use a grinder ... 30 seconds and its out.

A branded decent small anger grinder is £30 with cutting discs and last a very long time.

It will also remove the flared pins in about 10 seconds. Or the chain entirely in 20 if you feel lucky.

I bought mine because at the time it only cost ~£10 more than a splitter and is a much more useful tool.

It's also incredibly fun. I was loving cutting up a Mini exhaust the other week for the tip.

Bunch of girls - what's wrong with bolt cutters?
10 seconds and it's off, plus you get the satisfaction of using bolt cutters, and it's a lot cleaner than grinding.

[Prof Prolapse]

Only bike thieves own bolt cutters.

Plenty of chain tools get broken whilst trying to push out rivets that haven't had the head ground/drilled off. What's wrong with sparks anyway?

Just remember not to keep your angle grinder in the garage chaps. Otherwise it might be used to chop off your Almax chain

Is recommend getting a Dremel anyway, I have a cordless one and it's as handy as feck for all sorts of stuff. I use it for chains aswell!
