Why choose it

The TiAlN coating provides high hardness and thermal stability, allowing higher cutting speeds and longer intervals between regrinds. The three-flute design ensures smooth, chatter-free countersinking, while the cylindrical shank fits standard drill chucks and collet chucks.

Ideal use cases

• Countersinking holes for flat-head screws in machine construction
• Deburring drilled holes in steel and cast iron components
• Chamfering edges on non-ferrous metal parts
• Preparing plastic workpieces for assembly

Good to know

The countersink is manufactured to DIN 335 C, ensuring consistent geometry and compatibility with standard tooling. It is supplied as a single piece.
