Countersink set DIN 335 Type C 90° HSS - 17 pcs.

Because of the CBN deep-ground flutes the cutting edges are extremely sharp. Ideal for burr- and chatter-free deburring and countersinking. Best results at low cutting speeds. 17-piece set of taper and deburring countersinkers DIN 335 type C 90° Ø 4,3 - 5,0 - 6,0 - 6,3 - 7,0 - 8,0 - 8,3 - 10,0 - 10,4 - 11,5 - 12,4 - 15,0 - 16,5 - 19,0 - 20,5 - 23,0 - 25,0 mm

• Circular, burr-free recesses with a uniform surface.

• Over 30% lower feed force for comfortable working.*

• Over 50% shorter machining time with an average countersinking time of 8 seconds.*

• Up to 60% longer tool life.*

*The performance figures given are based on comparative tests with standard countersinks under identical conditions in the company’s own testing and experimental facilities. Test conditions: S235JR structural steel, material thickness 10 mm, countersink diameter 20.5 mm. Results may vary depending on the machine, material, tool dimensions and machining parameters.
