The Original Spitznagel DF-15DX 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. The DF-15DX is our 1000-rpm depth adjustable drill with large 3 inch tall C-clamp (DF-SPD48L). It will arrive with one 8.0 mm HSCO drill bit, two 8.0 mm Titanium Coated HSCO bits, one 10.0 mm Titanium coated HSCO bit, one-year warranty and our guarantee that this will be one of your most used and beloved tools. DF-15DX Kit includes: (1) 1000 RPM Spitznagel Spot Weld Drill (1) DF-1480 8mm HSCO Bit (2) DF-1680T 8mm Titanium Coated HSCO Spot Weld Drill Bit (1) DF-1610T 10mm Titanium Coated HSCO Spot Weld Drill Bit (1) Bottle of Pneumatic Tool Oil (1) DF-15INOIL In-line Oiler (1) Deluxe Storage Case 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. The drill weighs 5.1 lbs with C-Clamp and bit.
Use DentFix or Spitznagel drill bits only. The tool is sensitive to the length of the bit. Non-OEM bits void warranties. This depth adjustable spot weld drill applies the cutting pressure for you. It is important to release the trigger when the drill bit has stopped cutting. It is important in the operation of this tool that you have the Drill Bit sitting on the spot weld before you pull the trigger. Once it is on the spot weld pull the trigger and let the C-Clamp tighten up to the work. DO NOT let the drill bit slam into the weld. Doing that will cause the pilot tip to break making the drill bit ineffective.
1) Depth adjustment is accomplished by turning the blue adjustment ring. Check the drilling depth by pulling back the prongs at the front of the drill. The amount of drill bit above the prong indicates the drilling depth. 2) When used in conjunction with the C-clamp (arm) the drill will apply the cutting pressure against the spot weld. A) Hook the clamp around the back of the panel. B) Pull the trigger half way to move the drill bit into position against the spot weld. C) Pull the trigger completely back to start the drill bit turning and to apply maximum pressure. 3) The C-clamp is removable for applications on areas where the rear of the spot weld is inaccessible. A. ) When the C-clamp is removed it is important that the technician pulls the trigger half way first and fully extends the pneumatic head. B) Place your opposite hand under the belly of the drill, then use the thumb and fore finger of that hand on the prong to stabilize the drill. This will help prevent movement of the drill point. C) Pull the trigger completely to start drilling. 4) Air pressure greater than l00 psi will create too much pressure on the bit and prevent it from turning. Recommended is 90 psi.
Consumables 5) The cup and screw at the end of the C-clamp are designed to be replaced. Part# DF-SPD66 6) A 3-inch (DF-SPD48L) and 6 inch (DF-SPD48M) C-clamps are available. 7) Replacement drill bits 8.0 mm HSCO / DF-1480, 8.0 mm titanium coated/ DF-1680T, 10.0mm / DF-1610, 10.0mm titanium coated/ DF-1610T, 6.5 mm / DF- 1465.
