Dent Fix DF-1690 Boron Killer Tungsten Carbide Spot Weld Drill Bit 8x45mm

The Dent Fix DF-1690 Boron Killer is a specialized tungsten carbide drill bit engineered specifically to cut spot welds in Ultra High Strength Steel (UHSS), commonly known as Boron Steel. This advanced material is approximately three times stronger than regular high-strength steel and is used extensively by automotive manufacturers in structurally critical areas including B-pillar inner cores, intrusion beams, bumper reinforcements, and cabin strengthening components.

Key Features:

• 8.0mm diameter tungsten carbide construction designed to drill through and survive Boron Steel
• 3-fluted design distributes cutting forces over a greater area to prevent premature breakage
• Multi-layered special coating eliminates the need for lubrication during operation
• 45mm overall length optimized for spot weld removal applications
• Compatible with Dent Fix DF-15DX Spot Annihilator drill with Predator Approach technology

Application Guidelines:

For optimal performance and bit longevity, use with the Dent Fix blue-ringed 1000 RPM drill (DF-15DX) or the original red-ringed 1800 RPM drill with restricted air flow to reduce speed to approximately 1000 RPM. The carbide construction requires proper drilling pressure and speed control—using incompatible drills or incorrect technique may result in immediate bit breakage. This is the only drill bit capable of effectively penetrating Boron Steel used by manufacturers like Volvo and other brands focused on lightweight, high-strength vehicle construction.
