Countersink 6.3 mm, 90° – 3 flutes

Countersink 6.3 mm (90°) is an ideal choice for precise finishing work in metal, plastic, and wood. The three flutes ensure a smooth cut, reduce vibration, and create clean, aesthetic countersinks for countersunk head screws.

Thanks to its optimized geometry, it provides fast, clean deburring and edge chamfering without tearing the material. Suitable for workshops, on-site assembly, and home use where high precision and a fine surface finish are required.

• Clean countersinking for countersunk screws – a professional-looking joint
• 3 flutes for smooth engagement and long service life
• 90° angle – the standard for most countersunk heads
• 6.3 mm diameter – compact and versatile for common applications
