Made of special hi-molybdenum tool steel
Heat treated at 2185 degrees Fahrenheit and then nitro-carburized at -950 degrees
Measurably harder than standard high-speed steel
Feature a 135 degrees split point for faster penetration and accurate starting without a center punch
The body and clearance of this bit are “gold surface" treated for maximum lubricity
Designed for drilling in harder steels such as stainless
Less brittle than a cobalt bit, so you will not have the problem of chipping
They have tri-flat ½” shanks (which can be used in a ½” keyed chuck drill)
The shanks are flatted to prevent slipping
