Product Details
The 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 reduces thrust and allows for easier penetration; however, sizes smaller than .0625" do not include a split point. The kit includes drill bits with three flats on the shanks for sizes 3/16" and larger, enhancing chucking tightness. The black and gold oxide surface finish improves wear resistance and adds lubricity, facilitating better chip flow. This kit is suitable for drilling in various materials, including stainless steel, tool steel, alloy steel, and cast iron. The product is made in the USA and comes in a pack of 12 with a 30-day warranty.
