Engineers - what drill bits

[locksmith]

Need recommendations for HSS drill bits, just regular sizes ie. 2 - 12mm


Used Rawlplug for many years but they've obviously changed something as they blunt and snap real easily nowdays.


So what brands are good?

[davey boy]

I use Dormer at work. They work well on exotic stainless steels so should be good for you

[mickvp]

we use sandvik, seco, and walter in work. sandvik and walter are ok (I think they are the same company now), but seco are cheap sh*t.

I should point out that most of the tools we use in an industrial engineering environment are crown-loc drills now (the shaft is permanent and you just replace the tip of the drill).

I've sat with these for a while now - do the job for me every time

+1 for Dormer, long live the Jobber! Of course it all depends on what you're drilling.

Dormer thats a blast from the past, used to use them years ago and I can get them trade so I'll give them a try.

I use the bits every day on various lock fitting/drilling duties

A lot of the time it is not the drill that is the problem but the operator. Depending on what you are drilling it is down drill head speed, cooling fluid being used, or lubricant at the drill head. Most drill failures are down to not letting the bit do it's job, as in drill!!, not trying to punch the hole through.

[slimwilly]

Yes. True. S low head speed is a must.

[johnakay]

on harden steel you need to keep the drill sharp and correct speed as well as lube, I use Rocol lube.
stinks when hot but does the job.

Nope! Nor is it cool to pretend you are Robocop  :lol

if your drilling stainless steel you can get drill bits for drilling stainless steel, not much more expensive realy.
