3/8” (10mm) VSR Electric Drill
APPLICATION
WARNING: Always check the direction of rotation before operating the tool. When drilling,
the tool must be set for forward or clockwise rotation only. Failure to obey this caution may
cause property damage.
DRILLING IN WOOD, COMPOSITE MATERIALS AND PLASTICS
Although most “twist” drill bits are designed for drilling into metal, they are the most common
bit used for boring holes in wood, wood composites and plastics. There are many types of drill
bits available that may be more appropriate or designed specifically for boring the type of hole
you desire. Additional drill bits to choose from include: spade bits, brad bits, self-feed bits,
hole saws, circle cutters, multispur bits and forstner bits, to name just a few! Woodworking
publications and tool supply store personnel are good sources to help you select the drill bit that
best satisfies your needs.
With the tool unplugged from its power source
1. Install the appropriate bit into the chuck and tighten the chuck.
2. Place the forward/reverse switch in the forward position.
3. Mark the location(s) on the workpiece where the holes are to be drilled.
4. Secure the workpiece with clamps or other means.
5. Wear safety goggles or safety glasses with side shields. Wear a dust mask or
respirator to prevent inhalation of wood dust.
To drill the hole
1. Plug the tool into the power source.
2. Place tip of the drill bit on the workpiece where the hole is being drilled.
3. Apply downward pressure and slowly depress the switch trigger.
4. When using a twist drill, withdraw the bit from the hole frequently to clear built up
wood chips from the flutes. Clearing the flutes avoids overheating the bit and burning
the wood.
5. When drilling plastics, use slower speeds to avoid melting the material.
6. Reduce pressure on the drill just before the bit breaks through the workpiece to avoid
splintering the wood. (Note: Clamping a backing block to the workpiece will keep the
back of the wood from splintering. If not using a backing block when using spade bits
and hole saws, reduce pressure as soon as the bit point breaks through the workpiece
and complete drilling the hole from the opposite side.)
DRILLING IN METAL
Important Note: Use good quality high-speed steel twist drill bits.
1. With the drill unplugged, install the bit and perform the pre-drilling checks as stated in
the preceding wood drilling section.
2. To make starting the hole easier and keep the bit from “walking” on the workpiece,
use a center punch to make a small impression in the metal. Place the drill bit tip into
the impression and start the drill by slowly depressing the switch trigger. Apply only
enough pressure to keep the bit cutting into the metal.
WARNING: DO NOT FORCE the tool. Too much pressure may cause bits to break, resulting
in bodily injury. Excessive pressure will cause bits to overheat, damaging the drill bit. Too
little pressure keeps the bit from cutting, dulling the bit edges due to excessive friction.
