What Customers Are Saying

The cobalt drill bit received mixed reviews. Some customers found it highly effective, durable, and able to cut through tough materials. However, many reported the bit dulling, rounding off, or breaking after limited use, even on softer materials. The consensus is that the drill bit can work well for some applications but may not be reliable or durable enough for more demanding tasks.

Did Not Work

Would Not Recommend

I Purchased theses cobalt drill bit to make several 3/8 size holes on my trucks lower frame to install side steps. I tapped and made smaller size holes but even that did not help. I was unsuccessful in making the holes.

Sturdy and strong enough to go through steel as advertised. No problems and no slipping. I would recommend it.

Junk; do not buy

Would Not Recommend

As you can see in the photo, the bit twisted and bent while drilling MY VERY FIRST HOLE with it! This wasn't in a drill press; I was using a hand-held drill, and my wrists are not that strong.

a very long lasting bit

Would Recommend

I bought this bit to drill through a hardened knife handle. TiN and high speed steel would not do it. This bit worked well and is still sharp enough to drill regular steel. A good buy!
