THE ONLY HIGH-TORQUE DRILL WITH LOW SPEED FOR ULTRA HIGH STRENGTH STEELS.The “Original Spitznagel” Spot Weld Drill that applies the cutting pressure pneumatically. You do not have to push on the drill bit. Our patented valved cylinder applies gentle pressure toward the panel. When the drill bit starts to turn even more pressure is applied. This “Smart” pressure valve helps prevent breakage of bits and applies correct consistent pressure from the first to the last spot weld, ensuring the long life of your bits by preventing breakage. The 1000-rpm motor makes sure you do not burn up bits prematurely and is perfect for Higher Strength (HSS) and Boron Steels (UHSS). The DF-1690 specialized Tungsten Carbide drill bit is needed to drill through Boron steels.The ultimate spot weld drill lets you set the depth. Using the large blue adjustment ring you may set your drilling depth. Drill through only the top panel and leave the underlying panel clean and ready for the replacement. No plugs to grind off and no pilot drill holes to fill.This tool can drill through UHSS or Boron Steel when used with the DF-1690 Tungsten Carbide Bits. We have lowered the RPM on all our Spot Weld Drills so that our new bits for Boron cut more efficiently.Ultra High Strength (UHSS) also known as Boron Steel is used by many vehicle manufacturers to lighten the vehicles weight and increase gas mileage while increasing structural strength. Boron steel is about 3 times stronger than regular High Strength Steel. Thus you can form it half as thick yet increase crash worthiness. Volvo is an early adopter and heavy user. Typical locations are in structurally significant locations. Intrusion beams, inner core of the B-Pillar, bumper and cabin reinforcements are all likely places that contain this Ultra High Strength Steel.
