For maximum performance, use high speed steel bits for wood or metal drilling. Select drilling mode. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.

Wood Drilling:

1. Increase the speed as the drill bit bites into the material.
2. When drilling through holes, place a block of wood behind the workpiece to prevent ragged or splintered edges on the back side of the hole.

Metal and Steel Drilling:

1. Use a light oil on the drill bit to keep it from overheating. The oil will prolong the life of the bit and increase the drilling action.
2. Maintain a speed and pressure which allows cutting without overheating the bit. Applying too much pressure will:
   • Overheat the drill
   • Wear the bearings
   • Bend or burn bits
   • Produce off-center or irregular-shaped holes
3. When drilling large holes in metal, start with a small bit, then finish with a larger bit.
