Drill Bits
Always inspect drill bits for excessive wear. Use only bits that are sharp and in good condition.
Twist Bits: Available with straight and reduced shanks for wood and light-duty metal drilling.
High-speed bits cut faster and last longer on hard materials.
Carbide-Tipped Bits: Used for drilling stone, concrete, plaster, cement, and other unusually
hard nonmetal materials. Use continuous, heavy feed pressure when using carbide-tipped
bits.
Do not use the power of the drill while grasping chuck to loosen or
tighten the chuck jaws on the bit . Friction burn or hand injury is possible
Do not use bits with damaged shanks .
Use protective gloves when removing the bit from the tool, or first
allow the bit to cool down . The bit may be hot after prolonged use .
