Cordless Drill

drill safety

When drilling in forward, the bit will rotate in a clockwise direction.  If the bit binds in the hole, the bit will come to a sudden stop and drill will suddenly react in a counter-clockwise direction.

If the bit binds, the pipe handle or the motor housing braced against the stud will hold the drill in position.

To Reduce The Chance Of Bit Binding
-Use the proper bit for the job.  There are many types of bits designed for specific purposes.
-Avoid drilling warped, wet, knotty, and or pitchy material.
-Do not drill in material that contain nails or other things that may cause the bit to bind.

-Do Not Expose Battery Or Charger To Rain or Snow
Batteries – Never:

  • disassemble
  • incinerate
  • short-circuit
  • store in an area where the temperature may exceed 104 degrees
-Keep the battery away from direct sunlight.
-Pull by the plug when unplugging the charger.
-Never connect two battery chargers together.


Drilling in Wood, Composition Materials and Plastic

  • Start the drill slowly, gradually increasing speed.
  • When using twist drill bits, pull the bit out of the hole frequently to clear debris from the flutes.
  • Use low speeds for plastics with low melting point.
  • Before drilling, be sure the work piece is clamped securely
  • Use backing material to prevent damage to the work piece  during breakthrough

Drilling in Masonry

  • Use high speed carbide-tipped bits.
  • Soft masonry material (cinder block) requires little pressure.
  • Hard materials such as concrete require more pressure.
  • A smooth, even flow of dust indicates the proper drilling rate.
  • Do not let bits spin in the hole without cutting.  Do not use water to settle dust or to cool bit.  This damages the carbide.

Drilling in Metal

  • Use high speed steel twist drills or hole saws.
  • Slow speeds for hard metals and high speeds for softer metals.
  • Lubricate with cutting oil when drilling in iron or steel.
  • Use a coolant when drilling in nonferrous metals such as copper, brass or aluminum.
