Deep hole drill with high heat resistance to drill non alloyed and alloyed steels as well as long chipping materials with tensile strength up to 1,300N/mm2. Because of the special point design with web thinning form S optimised chip breaking and reduced feed force and torque. Ample chip space enables drilling over five times diameter deep without pecking.
Features and Benefits
High speed steel and cobalt construction for increased tool toughness
High heat resistance for prolonged tool lifespan
Maximum material tensile strength 1,300 N/mm2
Steam tempered finish for increased wear resistance
