Description
The DentFix 1667 6.7mm Tungsten Carbide STC Bit is the ultra-hard drill bit engineered for penetrating spot welds in ultra-high-strength Usibor and Boron steel panels—common in critical areas like intrusion beams, rocker rails, and A/B-pillars. At 6.7mm x 80mm, this tungsten carbide bit slices through without breaking, spreading cutting forces across three fluted edges for longer life and cleaner holes. Pair it with low-RPM drills (1000-1800 RPM) for flawless UHSS repairs that meet OEM standards, saving time on structural replacements.

- Tungsten carbide construction – ultra-hard for Usibor/Boron
- 6.7mm x 80mm size – precise spot weld penetration
