Through trial and error, I found that these cobalt cutters outlast any other bits in its class, delivering smooth and efficient drilling even in the toughest materials, with less stress and breakage.Ideal for industrial and DIY projects alike, these innovative cutting tools are worth every penny!
Almost 5 stars. The chisel easily cut holes in 3/8" zinc plated steel brackets and 2" steel drawbars. I used a drill press and lots of oil. One of the two cutters had 2 small chips after drilling through 3/8" stock. As this is a cobalt bit I wasn't shocked but I was less than thrilled. Revain handled it. Thing when drilling a 2- Inch bar The nature of the animal with cobalt I think Even with small chipping on a cutting edge the chisel still does a good job.
