8mm Coated Countersink
3-Flute Radially Relieved Tool for Optimized Finishing
Precision Countersinking Performance
This 8mm countersink is designed for precision finishing. Featuring three cutting edges that are radially relieved, it provides smooth, chatter-free operation. The flutes are ground from solid material for structural integrity, while the specialized coating offers improved performance and extended tool life compared to uncoated alternatives.
Key Technical Highlights
- • Design: 3 radially relieved cutting edges.
- • Manufacturing: Flutes ground from solid.
- • Compatibility: Optimized for M4 countersunk screws (ISO 2009, 2010, 7046, 7047).
- • Versatility: Suitable for holes starting from 2 mm.
- • Efficiency: Coated for superior performance in steel.
| External Ø | 8 mm |
| Shank Ø (Ds) | 6 mm |
| Shank Tolerance | h9 |
| Feed Rate (Steel < 500 N/mm²) | 0.09 mm/rev |
Understanding Countersinking
Countersinking is the process of creating a conical hole to allow a countersunk screw head to sit flush with or below the surface of the material. To learn more about how different cutting geometries affect the finish of your workpiece, consider the following:
