  • These round shank tools have flats ground onto three sides to reduce slippage of the bit when used in drill chucks
  • Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools; performance is similar to uncoated tools
  • High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance
  • 21 screw machine length drill bits ranging in size from 1/16" to 1/4" in 1/64" increments and from 9/32" to 1/2" in 1/32" increments
  • When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging

  • 29 Drill Pal mechanics length drill bits ranging in size from 1/16" to 1/2" in 1/64" increments
  • When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
  • Round shanks allow use with a wide variety of toolholding systems
  • Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools; performance is similar to uncoated tools
  • High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance
  • It increases hardness for drilling stainless steel and other hard metals. It resists corrosion and increases the hardness of the drill bit for additional wear resistance
  • 3-Flat shank is made of high-speed steel that provides long durability when drilling hard materials
  • Self-centering 140-degree split point penetrates extra-hard material without a pilot hole and produces small chips to reduce clogging
  • Black and gold oxide finish resists corrosion and increases the hardness of the drill bit for additional wear resistance
  • Nitride surface treatment on high-speed steel provides hardness for wear resistance
  • Jobber length drill bit has a midrange drilling depth
  • Designed for drilling stainless steel and other hard metals
  • It increases hardness for drilling stainless steel and other hard metals. It resists corrosion and increases the hardness of the drill bit for additional wear resistance
