Desalt bits

I can buy all Dewalt products with confidence that they will do the job and last.

Won't go threw SS Shelf Bracket

Burned through two of these drilling holes in a stainless steel shelf bracket. Bracket was maybe 1mm thick. Got maybe 6 holes out of one bit and one out of the other. Very disappointed.

Not great on Stainless Steel

I bought 2 of these to drill through some Stainless Steel shelving brackets. When first opened it was tough to get a hole started. I tried using cutting oil but not much luck. After one or two holes it was slightly better and I got about 6 holes done and it started to get harder and then simply wouldn't make it through the metal. I opened the new bit and it was worse. Wouldn't cut at all. I then probably pressed down too hard and burned it up in frustration. $8 down the drain. Not sure i...

It's a DeWalt

Did a good job on the bolt to prep for extraction.

Worthless on 1/8 Stainless Steel

Went through 4 of these bits attempting to bore through 1/8 SS, the "pilot tip" is extremely hard to keep cool. Went out and purchased 4 Milwaukee helix and, using the same cooling (oil) that I used with the Dewalt bits, I was able to drill fast and three times as many holes. They probable work great on Pine.

Cobalt Drill Bit

This bit did a nice job of drilling through soft metal and I liked the added centering tip to help start the holes.

Recommend!

This is a wonderful product, It did the things smoothly

title is appropriate

Drill Bit performed splendidly drilling 30 holes in 1/4 inch angle iron.

Did the job but with a lot of effort.

It completed the job as advertised but it took a lot of sweat and effort.

second one I've purchased, just work the first one out. It holds up well, works great on most metals. Haven't tried it on tempered steel. Will purchase again when this new one wears out.

It stays sharp a lot better than other bits I've tried.
