OPERATION
Operational Guidelines
The working materials should be within: “wood, metal, plastic, resin board, concrete”.
• When drilling hard, smooth surfaces, use a center punch to mark the desired hole
location. This will prevent the drill from slipping off center as the hole is started.
• The working material should be secured in a device or with clamps to keep it from
moving as the drill bit rotates.
Drilling Wood or Plastic
It is recommended to start the drill slowly and gradually increase the speed as you drill
into wood or plastics. Use low speeds for plastics with a low melting point. If backup
material is not used, ease up on the pressure just before the bit breaks through the wood
to avoid splintering. Finish the hole from the opposite side after the point breaks through.
If it binds, reverse the drilling operation to help remove the bit from the work.
Drilling Metal
It is recommended to use high speed steel (HSS) carbide tipped drill bits on metal. Use
low speed for very hard metals and high speed for softer metals. Make a center punch in
the metal to be drilled for easier starting. Use just enough pressure to keep the bit cutting.
Lubricate the tip of the bit occasionally with light oil for easier metal drilling. If it binds,
reverse the drilling operation to help remove the bit from the work.
Drilling Masonry
Use carbide-tipped masonry bits for cinder blocks, mortar, common brick, soft stone and
other materials. The amount of pressure to be used is dependent upon the type of
material being drilled. Less pressure is needed for soft materials and more pressure for
harder materials.
Stalling
If the drill bit has a tendency to bind or stall during an operation, maintain a firm grip and
reduce the tool pressure slightly to allow the drill bit to regain speed. If the tool does stall,
release the trigger immediately. Change the rotational direction of the drill bit using the
Fwd/Rev switch and remove the bit from the workpiece and start again.
