The Dent Fix Spot Annihilator Kit, No. DF-15DX, includes the company's Spitznagel Spot Weld Drill, which applies the cutting pressure pneumatically. There is no need to push on the drill bit because a patented valved cylinder applies gentle pressure toward the panel, and when the drill bit starts to turn, more pressure is applied. The 1,000-rpm motor prevents bits from burning up prematurely. The DF-1690 specialized Tungsten Carbide drill bit is needed to drill through Boron steels. The spot weld drill offers and adjustment ring that allows the user to set the depth and it includes a large, 3" C-clamp. The kit also includes an 8mm HSCO bit, two 8mm titanium-coated HSCO spot weld drill bits, a titanium-coated HSCO spot weld drill bit, one bottle of pneumatic tool oil, an in-line oiler and a storage case.
