TylerDama Posted April 21, 2014 Report Share Posted April 21, 2014 Hey there, just fishing for some information on drill bit sets. I am an electrician (apprentice) so most common applications I can think of would be drilling through aluminum brackets, EMT conduit, and maybe some PVC. the two sets I was most considering were the "Milwaukee Thunderbolt Black Oxide Drill Bit Set (21-Piece)" and "DEWALT Titanium Drill Bit Set (21-Piece)". I am open to other options and your thoughts. Thank you,Tyler Quote Link to comment Share on other sites More sharing options...
DR99 Posted April 21, 2014 Report Share Posted April 21, 2014 The titanium Dewalt bits are slightly better the titanium coating helps a little not too much but it does. 1 Quote Link to comment Share on other sites More sharing options...
TylerDama Posted April 22, 2014 Author Report Share Posted April 22, 2014 Thank you for your input, there is a special on a Ridgid Cobalt set... the packaging only implies it goes through metal, should I not use this on P.V.C. or wood?

DR99 Posted April 22, 2014 Report Share Posted April 22, 2014 Cobalt is mostly used for metal drilling. They are not as durable as other drill bits they are easy to break or shatter they are really meant for drilling in really hard metals. 1 Quote Link to comment Share on other sites More sharing options...
NicholasShetley Posted April 22, 2014 Report Share Posted April 22, 2014 You can use them for wood but like DR said they shine on harder metals. They work great for thick metal too. I have the 29 piece dewalt set and they are extremely quick as well. The only problem is they will be a pain to sharpen with the pilot point tip. They should be fine for your use. 1 Quote Link to comment Share on other sites More sharing options...
WIElectrician Posted April 22, 2014 Report Share Posted April 22, 2014 Hey Electrical Apprentice here too! I really think the only drill bit you need is a 1/4" drill bit to use for pilot holes for hole saws and j-boxes that don't have holes pre-drilled for screws. I would invest in a good holes saw kit, I have a lenox hole saw kit and they really hold up and stay sharp 1 Quote Link to comment Share on other sites More sharing options...
TylerDama Posted April 22, 2014 Author Report Share Posted April 22, 2014 Thank you all I will probably pick up the Dewalt set... maybe the hole saw kit in a while. 1 Quote Link to comment Share on other sites More sharing options...

DR99 Posted April 23, 2014 Report Share Posted April 23, 2014 Yea I never wore a drill bit out before I lose it. It's always the small sizes that seem to vanish. Quote Link to comment Share on other sites More sharing options...
Conductor562 Posted April 23, 2014 Report Share Posted April 23, 2014 For general purpose drilling the Thunderbolts or the tin coated Dewalt's will do fine. I use the thunderbts. $20 bucks for the set and after a couple years I toss them and replace. I do like the Dewalt pilot points, but they don't hold up worth a damn in steel.

Fazzman Posted April 29, 2014 Report Share Posted April 29, 2014 Just find some decent high speed steel drills and you will have good luck witht he materials you wanna drill Precision twist drill,rocky mountain twist drills just a couple examples you can research. Not sure i would even want to use a drill from a big box type store,but working in machine shops has made drill access easy for me. Lenox holesaws are very nice,cant say enough good things about mine. Quote Link to comment Share on other sites More sharing options...

I was impressed with them...I was using my dcd780 and I didn't like how hot it got...other than that fine... Quote Link to comment Share on other sites More sharing options...
