Type 170-AG Magnum Super Premium: Special Hi-Molybdenum tool steel with 135[DEG] split points for fast penetration and accurate starting without a center punch. Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance.
135[DEG] split point provides fast penetration and accurate starting without a center punch
Withstands substantially higher drilling temperature while maintaining sharpness
Body and clearance are gold surface treated for maximum lubricity
Drills are heat treated at 2185[DEG]F and then nitro-carburize finished at 950[DEG]F to be measurably harder than high speed steel
Space age nitro-carburized steel withstands substantially higher drilling temperatures while maintaining sharpness
Recommended for use in work hardening grades of stainless steel and other hard metal drilling applications
