Product Description
Proprietary Mach-Blue™ Armor Plating is a super hard surface plating that retains sharper cutting edges, and reduces heat build-up and cutting friction – resulting in faster cuts and exceptionally long drill life. Impact rated 1/4″ speed hex won’t slip in conventional 3-jaw chucks and ideal for use in quick change impacting power tools. Optimized 135° self-centering split point cutting geometry won’t walk or wander – even on pre-hardened or curved surfaces. Advanced M-Series alloy tool steel construction and proprietary heat treatment increase drill bit durability, rigidity and breakage resistance. Ideal for drilling stainless steel, mild steel, aluminum, stacked sheet materials and other tough-to-drill alloys.
3/16" To 7/8 " x 9 steps
