Prop 65 Warning

Many metalworking products do contain metals that are included in the latest Prop 65 warning. Exposure to the elements can be harmful. May cause cancer and reproductive harm.

Details
Suited for tougher materials such as alloys, stainless & manganese steels, etc.

Applications

  • For most general purpose, heavy duty, drilling operations for tougher materials.
  • While cobalt drills generally offer a variety of benefits for drilling all materials, they are especially well suited for heavy duty operations in high tensile strength, low machinability, ferrous metals and alloys.
  • The 135° split point works for drilling alloy steels, manganese steels, harder stainless steels and a variety of tough ferrous alloys.
  • Split point design is self-centering and reduces the thrust requirements.
  • May be used with hand held manual drills and either portable or stationary machines.
  • Suitable lubricating/cutting oils or appropriate coolant fluids are recommended for most drilling operations to achieve optimal performance & extended tool life.

Features

  • Right hand (clockwise rotation) cutting direction.
  • Standard two flute design.
  • Standard spiral, helical flutes.
  • Straight shanks that corresponds to the drill diameter.
  • Jobbers length corresponds to the drill diameter. The jobbers length used for each of these drills is variable and determined by the specific drill diameter, offering the best balance between overall drill rigidity and depth capacity for each drill diameter.

Technical Data

  • Manufactured from cobalt steel.
  • Cylindrically ground from the solid.
  • Heavy duty, general purpose drills.
  • 135° point angle and a heavier web.
