Spyder step bits with Mach-Blue Coating that reduces heat and wear
Features:
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
