Electric Drill

ELECTRIC DRILL

What this tool is primarily used for:

The Electric Drill is used for boring holes and driving screws into various materials. The main advantages of the Electric Drill over the Drill Press: there is almost no limit to where holes can be made in material and the Hand Drill is very portable. It should have a reversible motor, operated by a lever, speed control knob a torque setting control and a locking button to hold the switch in the on position.
Depending on the chuck size and drill bit shank, the largest bit used with this drill is generally 13mm. larger holes can be bored if using a hole saw, other accessories include: wire brushes, sanding discs, grinding stones and flap wheels which can be used for lighter work than an angle grinder.
   
SAFETY FOR THIS MACHINE:

ALWAYS BE AWARE of where your fingers are in relation to the drill bit
DO NOT USE bits that are dull, bent or damaged
MAKE SURE bit is centered in chuck and tightened before operating the drill
USE A CLAMP when drilling metal, this will help prevent the material from spinning into your body or hand
NEVER hold metal in your bare hand while drilling
AVOID awkward hand positions where a sudden slip could cause a hand to move into the drill bit or cutting tool
DO NOT ATTEMPT to drill material that does not have a flat surface, unless a suitable support is used
TO PREVENT ROTATION OF THE WORKPIECE, ALWAYS clamp your work securely to a table
DO NOT USE locking button unless the drill is mounted in a drill press stand or otherwise held stationary. The user may need to instantly release the on/off switch if the bit binds in the work piece
ALWAYS unplug the drill when attaching or changing bits or accessories

THINGS TO REMEMBER WHEN USING THIS MACHINE:
 
The electric drill can be started with the drill bit in contact with the work piece
To drill a through hole without splintering the bottom face, place the material on a scrap piece of wood. This also protects the point of the drill bit
to prevent rotation of the work piece, clamp the work secure to the table, either with a "C" clamp or the drill press clamp
when drilling into metal, a cutting lubricant should be used. Cast iron and brass/bronze should be drilled dry
Insert drill bits about 3/4" into the chuck and tighten securely by holding the rear half of the chuck and rotating the front portion in the clockwise direction
Do not insert drill bits so deeply that they cover the fluted portion of the bit
If the drill stalls, it is usually because it is being overloaded or improperly used. Release the trigger immediately, remove drill bit from work piece, and determine cause of stalling. DO NOT CLICK TRIGGER ON AND OFF IN AN ATTEMPT TO START A STALLED DRILL - THIS CAN DAMAGE THE DRILL
To minimize stalling or breaking though the material, reduce pressure on drill and ease the bit thorough the last fractional part of the hole
Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent jamming
