Spyder 1/8”-1/2” & 3/16”-7/8” Step Bit Set

Up to 50x more holes than titanium or black oxide drill bits
Up to 2x faster than titanium or black oxide drill bits
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
Made in the USA
