Does my Cordless Drill support both wood and metal drilling? 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: Increase the speed as the drill bit bites into the material. 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: 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. 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 When drilling large holes in metal, start with a small bit, then finish with a larger bit.
