Drilling
•Use sharp drill bits only.
•Support and secure work properly, as instructed in the Safety Instructions.
•Use appropriate and required safety equipment, as instructed in the Safety Instructions.
•Secure and maintain work area, as instructed in the Safety Instructions.
•Run the drill very slowly, using light pressure, until the hole is started enough to keep the drill bit from slipping out of it.
•Apply pressure in a straight line with the bit. Use enough pressure to keep the bit biting but not so much as to stall the motor or deflect the bit.
•Hold the drill firmly with one hand on the grip and the other hand on the bottom of the battery pack to control its twisting action.
•DO NOT CLICK THE TRIGGER OF A STALLED DRILL OFF AND ON IN AN ATTEMPT TO START IT. DAMAGE TO THE DRILL CAN RESULT.
•Minimize stalling on breakthrough by reducing pressure and slowly drilling through the last part of the hole.
•Keep the motor running while pulling the bit out of a drilled hole. This will help reduce jamming.
•Make sure switch turns drill on and off.
Drilling in Wood
Holes in wood can be made with the same twist drill bits used for metal or with spade bits. These bits should be sharp and should be pulled out frequently when drilling to clear chips from the flutes.
Drilling in Metal
Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which should be drilled dry. The cutting lubricants that work best are sulfurized cutting oil or lard oil.
Drilling in Masonry
Use carbide tipped masonry bits. Refer to Drilling section. Keep even force on the drill but not so much that you crack the brittle material. A smooth, even flow of dust indicates the proper drilling rate.
