1/4-Inch Cobalt Steel M35 Jobber Length Twist Drill Bits for Hard Metal, Stainless Steel, Pack of 12

I'm not typically a reviewer type. I'm a farmer, I work hard, play hard, and I'm typically more of a hammer type than a precision instrument type. I've broken every brand of bit you can imagine. Last night I sheered off some bolts on a tractor, and I was drilling it out to use an extractor. I burned up 2 Milwaukee bits, before I got these out. These bits are nothing short of impressive. I went right through a grade 8.8 (metric) bolt with the first bit. Drilled out the other two with the same bit. Checked it afterwards and it still has enough edge to use again. Will def buy again. 10/10

The best bits I have ever had

Quality drill bits. Cut over 300 holes through 1/8” hardened steel & still cutting great.

Works as expected

Drilled 40 holes through 1/4 angle

These bits are amazing. Against all practice to drill metal slow and easy with oil. One of my employees accidentallyput a desalt cordless in high speed(3) and was able to drill 3/8 steel in 10 sec. 3 of us drilled 850 holes into 3/8 with 24 bits. I do have to say that about 3-5 bits would not drill. 850 holes on a vertical wall

Best bits for metal. Tried many others.

The real deal! I need to drill over 350 holes in the steel girts of this flat pallet shipping rack. These drill bits live up to their billing. With a drop of 3 in 1, I was making chips in no time, and could get the eight holes drilled in each girt in about 2 minutes flat! I used up just 2 of them to drill the first 96 holes.I am very happy with this purchase!
