Description
The DentFix DF-1690 Tungsten Carbide Drill Bit is the ultimate boron killer for collision shops, engineered to penetrate ultra-high-strength steel (UHSS) spot welds in intrusion beams, B-pillars, rocker rails, and bumper reinforcements without breaking or burning out. This 8mm x 45mm, 3-fluted bit with special multi-layered coating survives the toughest boron steels up to 1500 MPa, delivering clean cuts at 900-1000 RPM on the DF-15DX Spot Annihilator. Not for off-brand drills—pair it with the original for maximum durability and zero contamination.
