WARNING: TO REDUCE THE RISK OF PERSONAL
INJURY, ALWAYS ensure workpiece is anchored or
clamped firmly. If drilling thin material, use a wood
"back‑up" block to prevent damage to the material.

hole saws. For METAL, use high‑speed steel twist drill bits
or hole saws. Use a cutting lubricant when drilling metals.
The exceptions are cast iron and brass which should be
drilled dry.
2. Always apply pressure in a straight line with the bit. Use
enough pressure to keep the drill bit biting, but do not
push hard enough to stall the motor or deflect the bit.
3. Hold tool firmly with both hands to control the twisting
action of the drill.
