Description

Conical countersinks from PFERD are characterized by their particularly sharp blades that are able to achieve very good results, even at low cutting speeds.

High-performance countersink tools with a countersink angle of 90° for countersinking 90° screws for all common materials such as steel, cast steel and non-ferrous metals.

Advantages
  • Very high stock removal rate and optimum chip removal.
  • Burr-free results even at low cutting speeds.
  • Long tool life.
  • High workpiece surface quality.
Recommendations for use
  • Use cutting oil or compressed air as a coolant/lubricant.
  • Particularly well suited for producing countersinks for 90° screws.
