Magnum drill bits use special Hi-Molybdenum tool steel and feature a 135° split point for fast penetration and accurate starting without a center punch. They withstand substantially higher drilling temperatures while maintaining sharpness. Body and clearance are gold surface treated for maximum lubricity. These rill bits are heat treated at 2185° F and then nitrocarburized at 950° to be measurably harder than high-speed steel.

I'm NOT doing each individual drill bit. I've ordered from you for several years. I've been very pleased with the quality and service. On this order I placed, I used an account. NEVER did figure out how to log out. Pretty frustrating. Tell Les I said hi.
