Problem: Drilling and tapping operations typically require the use of different tools throughout the job.
Solution: A do-it-all cap screw drill and tapping tool combination saves time and effort by completing both operations with a single pass.

Produce Clearance Holes In A Single Pass- For Cap Screws Or For Taps

Benefits

For Cap Screws
  • Drills cap screw clearance holes.
  • Does 2 jobs in a single pass.
  • Can be sharpened repeatedly.
  • Modified for any special length-of-step.
For Taps
  • Drills 45° chamfered holes to be tapped (to produce approximate 70% thread).

Applications

  • Designed for drilling mounting holes for socket-head cap screws.
  • The dual cutting diameters produce holes properly sized for each size screw.
  • The two styles available permit the holes to be drilled for both through holes and tapped holes. The through hole style produces holes with a body diameter slightly larger than the major diameter of the screw. The tapped hole type drills holes with the diameter needed for tapping the holes to approximately 70% thread. Both types also produce a counterbored area correctly sized for the screw head.
  • Suitable for a range of ferrous and non-ferrous metals and alloys, and non-metallic materials.
  • The cutting lengths are sufficient to permit repeated sharpenings.
  • For optimal performance and the best tool life, suitable lubricating/cutting oils or the appropriate coolant fluids are recommended.

Features

  • Right hand (clockwise rotation) cutting direction.
  • Standard two flute design.
  • Standard spiral, helical flutes.
  • Cuts both body and counterbore diameters in a single pass.
  • Straight shanks that corresponds to the drill diameter.

Technical Data

  • Ground from the solid.
  • Cylindrically ground.
  • Permits repeated sharpenings.
  • Bright finish.
