Svasatore con perno RUKO FLS-DIN373-HSS-TiN-M-6x, M6, rivestito TiN

Creating precise counterbores for M6 screws in metal and plastic is challenging without the right tool. This RUKO counterbore with pilot, DIN 373, solves that by combining a pilot for accurate centering with a three-flute design for smooth chip removal. The TiN coating on high-speed steel extends tool life and reduces friction, making it suitable for steel, cast iron, non-ferrous metals, and plastics.

Who is it for

Machinists, metalworkers, and maintenance technicians who need to recess M6 socket head or cylinder head screws flush or below the surface in workpieces.

Main features

• Pilot diameter 6.4 mm ensures alignment with M6 clearance holes.
• Counterbore diameter 10.2 mm accommodates standard M6 screw heads.
• Three flutes optimize chip evacuation and reduce vibration.
• TiN coating provides high wear resistance and lower friction.
• HSS base material withstands high cutting temperatures.
• Cylindrical shank 6 mm fits standard drill chucks.

Tips

Use a cutting fluid when working with steel to prolong tool life. Ensure the pilot hole is drilled to the recommended size for M6 (typically 6.4 mm) before using the counterbore.
