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.
Batteries
-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
-Pull by the plug when unplugging the charger.
-Never connect two battery chargers together.
Drilling
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.
