DRILLING IN WOOD
For maximum performance, use high speed steel or brad point bits for wood drilling.
1. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
2. Increase speed as the drill bit bites into the material.
3. 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.
DRILLING IN METAL
For maximum performance, use high speed steel bits for metal or steel drilling.
1. When drilling metals, use 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. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
3. 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
DRILLING IN MASONRY
For maximum performance, use carbide-tipped masonry bits when drilling holes in brick, tile, concrete, etc.
1. Maintain a speed and pressure which allows cutting without overheating the bit or drill. Applying too much
pressure will:
• Overheat the drill.
• Wear the bearings.
• Bend or burn bits.
• Produce off-center or irregular-shaped holes.
2. Apply light pressure and medium speed for best results in brick.
3. Apply additional pressure for hard materials such as concrete.
4. When drilling holes in tile, practice on a scrap piece to determine the best speed and pressure.
5. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
WARNING! Always wear safety goggles or safety glasses with side shields during power tool operation
or when blowing dust. If operation is dusty, also wear a dust mask.
WARNING
technician a ! To ensure safety and reliability, all repairs should be performed by a qualified service
