Product Details
This heavy-duty drill bit kit is designed for drilling in tougher materials and is manufactured from high-speed steel. It features a 135° P3 split point that is self-centering, which helps reduce thrust and allows for easier penetration, although sizes smaller than .0625" do not have a split point. The shanks of sizes 3/16" and larger come with three flats for tighter chucking. The black and gold oxide surface finish enhances wear resistance and adds lubricity, thereby improving chip flow. This kit is suitable for drilling in stainless steel, tool steel, alloy steel, and cast iron. It is made in the USA and comes in a pack of 12, backed by a 30-day warranty.
