Drill, Corner, Slit or Slot with Manually Operated Drill Head Fast Setup Adjustable stops on the backgauge allow you to easily set any hole pattern. For even quicker setup, purchase our optional fixed gauges with pre-set stops for standard hole patterns. Easy to Adjust Thumb screws easily lock the backgauge to the drill table. To adjust your margins, simply loosen the screws and line up the gauge with the dual scales located on the drill table. Corner, Slit, and Slot Optional attachments make your Challenge single-spindle drills even more productive. Round cornering attachments can corner lifts in 1/8", 1/4", 7/16", or make straight diagonal cuts. For slitting, slotting, or V-slotting drilled holes, use our special 1/2" lift capacity slit/slot attachment. Automatic Chip Disposal Paper chips travel up through the drill bit and drop into a removable waste bin. Your jobs keep moving and clean-up time is kept to a minimum. 2" Lift Capacity Large two-inch drilling capacity is available with Challenge 1/4" to 1/2" diameter drill bits. Smaller drill bits will handle lifts from 5/8" to 1 5/8", depending on the bit size. Features:
