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