Counters.Bit 90° DIN 335C HSS, MULTI-TT

• Taper and deburring countersink bit with three blades and
optimised geometry for a longer service life and faster sinking Your Advantage / Benefit
• Optimised chip removal geometry provided by combined
axial/radial relief with larger relief angle 25 % longer service life
• Enlarged chip space 30 % faster sinking
• 3-sided shaft, cylindrical MULTI-TT coating (TiAlN / TiN Multilayer), with good wear
• Multi-TT coating (TiAIN/TiN Multilayer) behaviour and thermal stability for a longer service life
• Coating hardness: 3,100 HV Optimised chip removal geometry provided by combined
• Coating thickness: 2 µm axial/radial relief with larger relief angle for faster, vibration-free,
and scratch-free countersinking with low wear, no formation of
• Temperature resistance of coating: 650 °C built-up blades
• Made in Germany
Enlarged chip space for improved chip removal, even for long-
chipping materials
3-sided shaft for a force-fit connection and good torque
transmission, prevents slipping in the drill chuck
