Countersinks

Countersinks belong to the standard products in the tool industry. Almost no drilling takes place without sinking. Countersinking is used for secondary machining of the materials and provides them with the final surface finish. That is why Karnasch relies on the highest quality and the latest tool technologies for countersinking. Karnasch countersinks are available in different designs for every application. The special BLUE-TEC tool coating makes the countersinks by Karnasch additionally unique.

Karnasch countersinks for the machining of steel, cast iron, non-ferrous and light metals, stainless and acid-resistant steels and titanium alloys on CNC machines

Countersinks belong to the standard products in the tool industry. Almost no drilling takes place without sinking. Countersinking is used for secondary machining of the materials and provides them with the final surface finish. That is why Karnasch relies on the highest quality and the latest tool technologies for countersinking. Karnasch countersinks are available in different designs for every application. The special BLUE-TEC tool coating makes the countersinks by Karnasch additionally unique.

Karnasch Professional Tools countersinks are available in HSS-XE, ASP powder steel, solid carbide- and carbide-tipped types, with diameters from 4.3 mm to 80 mm. The special BLUE-TEC tool coating significantly increases surface hardness and tool life. CBN deep-ground flutes enables nearly burr- and chatter-free countersinking.

Due to the wide range of countersinks, nearly all steels that are difficult to process (such as stainless and acid-resistant steels), titanium and titanium alloys, light metals and other types of steel, can be machined. The cutting edge geometry of the countersinks has been optimized especially for automatic and rapid feed, enabling up to 30% faster countersinking and up to 40% longer tool life (RAPID-CUT version).

3 SURFACE SHANK
3 surface shank results in excellent torque transmission. No slipping in the chuck. Significantly higher cutting performance.
DIAMETER RELIEF ANGLE
Every diameter is given a clearance angle at its circumference. The largest cutting diameter is thus always the highest point.
AXIAL CBN RELIEF GRINDING
Clear cut with low heat generation.
CBN RELIEF GRINDING
Radially adapted CBN relief grinding according to the diameter. The cutting edge is always the highest point in the diameter.
CBN DEEP-GROUND FLUTES
CBN deep-ground flutes result in considerably higher burr clearance and sharpness compared to milled flutes. This results in a significantly higher cutting performance and tool life.
