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.

Safety notes

To ensure reliable torque transmission, conical countersinks have a three-surface shaft from a countersink diameter of 28 mm.
