Description

Conical countersinks from PFERD TOOLS are characterized by their particularly sharp flutes 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 particularly tough and hard materials such as alloyed and high-strength steel and stainless steel (INOX). Long tool life and temperature-resistant version due to Co content.

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.
