Description

Conical countersinks from PFERD TOOLS are characterized by their particularly sharp right-hand flutes that are able to achieve very good results, even at low cutting speeds. In addition, conical countersinks with a HICOAT coating provide good high-temperature hardness and resistance to oxidation. They can therefore also be used on hard materials without the addition of coolants.

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. To ensure reliable torque transmission, conical countersinks have a three-surface shaft from a countersink diameter of 28 mm. Thanks to the HICOAT coating HC-FEP, they have high hardness and wear resistance. They are very temperature resistant and have a particularly long tool life. They can also be used in a higher cutting speed range and without coolants and lubricants.

Recommendations for use

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.
