M35 tungsten-cobalt alloy drill bit, S2 industrial man treatment, not easy to break in the course of use
Carbide drills do not need to be punched in advance and can be used directly on iron without increasing the complexity of use.
M35 cobalt alloy, the use of special processing technology, not only more wear-resistant in the process of use, the hardness is also very good.

Steel Vision Cobalt drill bits are durable tools for most jobs. They are made from M35 alloy steel with a fully polished or honed finish to resist rust and corrosion. The heat-treated process gives the drill bits a significant hardness boost and makes them less likely to break. The stepped drill bit greatly increases the efficiency of labor, and when drilling holes in metal materials, the holes can be punched directly without having to do it in advance.

These drills will go they ANYTHING!Just go slow. No high speed drilling. They’ll go thru hardened steel like butter.

These worked better than I expected. They cut right through the steel trusses I was working on. I would definitely recommend these.

These bits dull very quickly and that's drilling aluminum.

This new drill bit set will really surprise you. With the stepped tips you don’t really need to center punch any more and I chose the hex shank for use in multiple drills and drivers

These drill bits work amazing! Drilled through 1/4” steel today and it was like slicing butter. Packaging was excellent and the seller even threw in a gift (61 pc screwdriver and security bit set) with a thank you letter. Highly recommend!

I've been using these for drilling into metal and I'm impressed. Less changing drill bit sizes to step up to larger holes, less worry about walking and wobbling than with standard bits. I still like to use a punch to get them started, particularly with a hand drill as opposed to a drill press, but these are great, especially in this, hard metals like stainless. I appreciate the cool old school metal case, which seems bombproof and looks cool. Price is reasonable for what you get.
