Best drill bit for drilling through a wrench?

[rlitman]

You guys rock!! I got through the wrench without any problems using the Irwin Multi-Material drill bit (4935109) listed in the picture. My drill press was set at 1100 rpm but I should have changed it to 600 which was the next option on my machine.

Multi material bits rock! Just last week, I had to drill through a steel door frame set in concrete. Nothing else would have done the job.
I haven't seen that Irwin one yet, but it's good to know I can buy them in single sizes too.

Well done John me old Chap. I love it when a thread turns into a plan, and then
into success. There are some great people on this form, hats off to the rest of you.

Thanks Mate!

Sorry, I Know success as achieved, the hole was drilled, and it's sort of a moot point now, but I was just looking thru the classifieds and saw the exact type of drill bit used for hardened steel. This is the link in case anyone wants to drill their own wrenches.

I'm glad I stumbled across this thread. I was trying the same thing, except with a handheld drill. I wasn't getting very far and finally gave up. I might just give it another go with that special bit.

Just make sure you use some oil to cool the bit and you'll be good to go.

I would just take the wrench to work and ask one of the guys to drill the holes for me at lunchtime :O

That's the same reason I take my locks to a locksmith!

 

[rlitman]

That is so not in the GJ spirit.

 

[jeffmoss26]

I do most of my own lock work too

Can you imagine the reaction if an IT/phone guy asked to use some of the power tools at work?

Happens all the time. I am a system admin/DBA/network admin/etc. and I actually weld things up for my workplace (DOD contractor). I go into the tool room and use the lathe, mill, surface grinder, etc. Don't be fooled!

We needed to make a HMMV mount for the whip antenna because we ordered X and needed Y. I said measure it out and I'll have it welded tonight and in work tomorrow.

If you want a nice clean hole, EDM. I've used carbide HI-ROC's but it's just slow going.

Outlaw, c'mon, I don't do it myself lol
Gotta have friends in the right places
Maybe one day I'll have my own Bridgeport!

I learned all I needed to learn when trying to drill out a busted locking bolt on my Volvo (lost its shape due to a crack and key would not work anymore). I tested it at work and it was 60Rc. HSS, even TiNi-coated HSS did nothing. Cobalt worked but dulled quickly so it was slow progress. I then got masonry bits with carbide tips and drilled slowly. I mean under 100rpm slow. It cut like butter. Brittle as hell, and I had to do this freehand, so I went through two bits. It worked though. I was getting close to giving up and cutting the $300 alloy wheel off the car.

I know I am just echoing what guys have already said, jut telling you m y experience.

I'm not implying they can't do it, but the reaction from a shop manager will usually be or there would be a policy about "qualified" personnel only...

Yep, skilled friends is always good, and better still if they teach you as you go as well. (I'm a sponge that way...)

You got it

Well, I've been following this thread, and finally decided to make a wrench handle for my HF cart. I put the wrench in the vise, chucked up a 9/64" drill bit, and went to town on it. My standard Dewalt coated bit ate right through it in seconds. I even drilled through the thick part where the handle meets the head...
