DrillingSolidIndexableIndexableHead TypeInsert TypeReamersBrazedOthers Thrust (N) Drill for Heat-Resistant Alloys SGS Type ■ General Features SGS type drills for heat-resistant alloys employ a sharp cutting edge to reduce heat during drilling (reduce cutting force) and provide a long, stable tool life. J ■ Features and Applications ● Long tool life · Combination of optimised cutting edge design and dedicated grade significantly reduces wear. · Minute honing (edge treatment) amount and special thinning shape reduce cutting force. This reduces cutting edge breakage. · Perfect for drilling Ni-based heat-resistant alloys (Inconel/Waspaloy/Hastelloy). ■ Product Range Cat.
