Heavy duty geometry for drilling tougher materials by hand or machine. Shorter flutes and overall length provide superior rigidity to minimize deflection when using heavy feed rates. Manufactured from premium cobalt high-speed steel. 135° split point is self-centering for reduced thrust and easier penetration, sizes under .0625 do not have split. TiAlN (Titanium Aluminum Nitride) coating combines the ability to work in high temperatures, with added hardness to increase drill life. For drilling in alloy and carbon steel, stainless, cast iron and tool steel. Made In USA. Pack Of 6. 30 Day W
