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

• • 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.
  • 1/4" To 3/4" x 9 Steps
  • MADE IN USA
