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 for through holes with the quality grade medium (M) according to ISO 273.

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 with the quality grade "medium" are suitable for producing flat countersinks at through holes or blind holes in the tolerance range "medium" with extended mounting accuracy.
