Questions & Answers

Question is about Thunderbolt Cobalt drill bit specifications

Item description does not specify either hardness (M42, M36, etc.) or Cobalt percentage (5%, 8%, etc.). Are these bit solid Cobalt Alloy Steel or simply coated High Speed Steel bits? Item description also says they are Titanium coated, probably a typo.
Asked by: ztywa6
Solid cobalt and titanium coated. I used this bit to drill through a grade 8 bolt and stainless steel. Used new bits both times. Light lubricant recommended during use. I've used non-titanium coated bits before and they work just as good.

5/64 in. Cobalt Red Helix Drill Bit is rated 3.8 out of 5 by 220.

I was able to easily drill a 1/16 pilot hole (Dewalt). When I tried to use the 1/4 drill bit it was totally UNABLE to penetrate. It took a lot of angling with it and over 5 MINUTES to drill the hole through 1/16 thick steel. WASTE OF MONEY!!!!

Bought two bits--this and one other, needed to drill a hole through 1/8th inch angle iron (5 ea), and a hole through 14 ga 2x2 square tube (5ea), got the job finished, but just barely. Doubt the bits are much good for anything more.

Rated 5 out of 5 by from Great bit. Flats on the shank help prevent spinning... Great bit. Flats on the shank help prevent spinning in the chuck. I subjected it to hard duty, enlarging 3/8" holes in my trailer tongue jack and "drop leg." After damaging the jack leg, I had to cut about 2" off the end. Then I re-drilled the hole in the jack, but it was not perfectly aligned. So I used the bit to slightly enlarge and re-align the holes in the drop leg. The bit held up to this abuse. But, it was very expensive for a single bit that I may never use again. My primary complaint is that HD was out of stock on 3 other grades of bits, and this was the last one in this size in the most expensive bit. I'm not sure why 7/16" inventory is allowed to dwindle to nothing.

I'm drilling through the metal bands of a wine barrel to place grommets. I was using the basic ones from a Ryobi drill bit set but that one walked and took a a couple minutes for each hole. The first two holes worked well for this Milwaukee bit, then it slowed down on the third. After finally completing the fourth hole, I noticed that half the bit was gone. So much for "Hard Metal." I switched back to the Ryobi bit and finished the project slowly. Waste of money on my part.

Rated 1 out of 5 by from Not meant for hardened steel These bits are probably pretty good through soft and mild steel however they would not self start in hardened steel had to use diamond tip(also Milwaukee brand and also under preformed expectations) before it would even think of taking a bite. Package says "Hard Metal" yeah right first (and 2nd) time I have ever been disappointed with Milwaukee products, do not buy stick with Dewalt

I bought it after realize it would take hours to drill a dozen holes with a conventional bit. I had drilled only 2 holes in ten minutes when the conventional bit broke. After purchasing the cobalt bit the job was finished in under twenty minutes.
