DEWALT Titanium Nitride Drill Bit Set, 21-Piece (DW1342)

I bought this for at-home DIY projects. The storage is perfect and keeps everything really well organized. The actual drill bits are incredible strong and easy to work with. I bought a Dewalt drill and driver set that comes with a sturdy canvas bag. These fit in easily so all my drill and driver tools are stored together.

Excellent Price, Excellent Quality, Fast Shipping! Buy with Confidence.Thank you,

I needed to drill into some metal for a few projects, and my go-to bit set was not up to the task. I was a little worried that somehow these wouldn't work based on the various reviews. I should not have worried. First, I drilled out a steel screw on a bicycle that had sheered off - it worked and I was able to tap the hole for a new screw. I drilled into a steel roof and through the support beam below it to secure a chimney cap. I drilled 20 holes in a steel cart (pulled by an ATV) so we could use bungee cords on it, and I drilled through a thick steel hook that goes over a roof peak (to hold a ladder on a roof) to add a bolt to keep it in place. In each case, I used some 3-in-1 oil to lubricate the hole(s) as I went along. I couldn't be happier with the purchase. It was worth every penny! I like being able to fix things, and these bits made me happy!

I use a set of these 21-piece Titanium Nitride drill bits at my full time tech job for drilling through hard wood, soft wood, aluminum, steel, epoxy, and various types of plastic materials. I set the full size drill press at the recommended speed for the size of bit and type of material needing to be drilled. There is a can of lubricant near by for any metal drilling. These bits get used with a Dewalt hammer drill when the task is too large or not convenient for a drill press.I have a set of these drill bits at home. They have been used on various projects around the house and on some commercial construction jobs working for my dad for some side hustle income in the past.Great quality bits. Boss bought a large set from Harbor Freight. Sizes are slightly off and bits do not stay sharp long. There is almost every size bit I need in this set for my tech job. Yes, my boss reimbursed me for this set.

This is the perfect set to throw in your drill bag! These bits hold an edge very well! I have drilled lots of steel with these and they hold up great!As with all drill bits, when drilling steel, go at a slower speed amd provide lots of pressure. Using an oil or coolant will also help the life of the drill. Running the drill too fast and not enough pressure will burn up any drill bit.

Excelente.
