Description

High-performance flat countersinks made from HSS according to DIN 373 for countersinking cylinder head and hexagon screws as well as nuts. Flat countersinks have a cylindrical design. The cylindrical pin in the relevant quality grades of fine, medium or tapping hole ensures coaxial alignment of the countersink to the bore.

High performance countersink tools with guide pins for the tapping hole (GKL).

Advantages

Very high stock removal rate.
Optimum chip removal.
Burr-free results.
Long tool life.
Smooth operation.
Good surface quality.

Recommendations for use

Please observe the recommended rotational speeds.
Flat countersinks for the tapping hole are suitable for producing flat countersinks at core holes for female threads.
