Product Details
This heavy-duty drill bit set is designed for drilling in tougher materials and is manufactured from high-speed steel. Featuring a 135° P3 split point, the bits are self-centering, which reduces thrust and eases penetration, although sizes smaller than .0625" do not have a split point. The black oxide surface finish enhances wear resistance and adds lubricity, promoting improved chip flow. This set is suitable for drilling in stainless steel, tool steel, alloy steel, and cast iron. Made in the USA, it comes in a pack of 12 and is backed by a 30-day warranty.
