Feature

●Taper and deburring countersink 90° with cyl. Shaft, HSS TiN-coated
●Design: Axial and radial ground as well as CBN deep-ground. Also equipped with chip and clearance angles for the most common materials.
●Application: for universal, chatter and burr-free countersink, countersink and deburring work for countersunk screws DIN 963, DIN 964, DIN 965 and DIN 966 in one go.
●The excellent cutting properties and the problem-free chip drain result from the conical back grinding on the sheath and chip angle. The countersink achieves the best results with a large feed and low cutting speed.
●Note: Sufficient coolant supply is essential for the uncoated versions.


Description

Taper and deburring countersink 90° with cyl. Shaft, HSS TiN-coated.

Design: Axial and radial ground as well as CBN deep-ground. Also equipped with chip and clearance angles for the most common materials.

Application: for universal, chatter and burr-free countersink, countersink and deburring work for countersunk screws DIN 963, DIN 964, DIN 965 and DIN 966 in one go.
The excellent cutting properties and the problem-free chip drain result from the conical back grinding on the sheath and chip angle. The countersink achieves the best results with a large feed and low cutting speed.

Note: Sufficient coolant supply is essential for the uncoated versions.
