Ring Clamp, Extension, and Side Handle for Right Angle Drive Unit
For D-handle drill with Right Angle Drive Unit:
A ring clamp, extension, and side handle are supplied with the Right
Angle Drive Unit. When using a right angle drive unit, attach the side
handle to the ring clamp. Do not use the extension when using the ring
clamp. The ring clamp with attached side handle clamps onto the right
angle drive unit and can swivel 360° and locked tight in any position.
For D-handle drill without Right Angle Drive Unit:
When using the D-handle drill without the right angle drive unit, remove
the ring clamp with attached side handle, then remove the side handle
from the ring clamp. Attach the side handle to the extension. The side
handle can be installed on either side of the tool for right or left handed
use. To install the extension with attached side handle, thread it into the
socket on the desired side of the tool (for right or left-handed use) and
tighten securely.
NOTE: If you have an extra ring clamp with attached side handle and
extension with attached side handle, do not use the extension with
attached side handle when using the right angle drive unit. Remove it
from the tool.

1. Remove the chuck from the drill following instructions (see "Removing
the Chuck from the Drill"). Slip the double hex coupling (1) over the
hex on the drill spindle.
Loosen the clamping screws on the clamping sleeve (2) and slip the
sleeve onto the drill collar.
2. Slide the right angle drill head (3) into the other side of the sleeve and
turn the drive head slightly in either direction so the hexagonal hole
in the coupling engages the hexagonal portion of the spindle.
Selecting Bits
When selecting a bit, use the right type for your job. For best perfor-
mance, always use sharp bits.
Drilling
1. Before drilling, be sure the workpiece is clamped securely. Use back-
ing material to prevent damage to the workpiece during breakthrough.
2. When starting a hole, place the drill bit on the work surface and
apply firm pressure. Begin drilling at a slow speed, gradually increas-
ing the speed as you drill.
3. Always apply pressure in line with the bit. Use enough pressure to
keep the drill biting, but do not push hard enough to stall the motor.
4. Reduce pressure and ease the bit through the last part of the hole.
While the tool is still running, pull the bit out of the hole to prevent
jamming.
Drilling in Wood, Composition Materials and Plastic
When drilling in wood, composition materials and plastic, start the drill
slowly, gradually increasing speed as you drill. When drilling into wood,
use wood augers or twist drill bits. Always use sharp bits. When using
twist drill bits, pull the bit out of the hole frequently to clear chips from the
bit flutes. To reduce the chance of splintering, back work with a piece of
scrap wood. Select low speeds for plastics with a low melting point.
NOTE: Attaching the drill chuck to the side designated "low" reduces
the speed by 1/3, or 33%. Attaching the drill chuck to the opposite
side of the right angle drill head increases the speed by 1/2, or 50%.
3. When assembled, turn the right angle head to the desired position
and tighten the clamping screws to secure the unit. Thread the
chuck onto the right angle drive spindle and install the chuck screw.
Removing the Chuck from the Right Angle Drive Unit (Fig. 3)
The chuck can be removed from the right angle drive unit in the same
manner it is removed from the drill; however, ALWAYS REMOVE RIGHT
ANGLE DRIVE FROM THE DRILL BEFORE ATTEMPTING TO LOOSEN THE
CHUCK. This will prevent damaging the drill's gearing. Use the open end
wrench provided to hold the right angle drive spindle before attempting
to loosen the chuck.
Removing the Chuck from the Drill (Fig. 4)

1. To remove the left-hand screw inside the chuck, remove the battery
pack from the tool and open the chuck jaws. Insert a T-handle hex
key into the screw inside the chuck. Turn the T-handle hex key and
remove the screw. Save the screw for installing your new chuck.
2. To remove chuck: Tighten a large hex key into the chuck. Place the
chuck on a workbench as shown. Strike the hex key with a soft-
headed mallet to loosen the chuck. Remove the chuck by hand.

APPLICATIONS

Drilling in Metal
When drilling in metal, use high speed steel twist drills or hole saws. Use
a center punch to start the hole. Lubricate drill bits with cutting oil when
drilling in iron or steel. Use a coolant when drilling in nonferrous metals
such as copper, brass or aluminum. Back the material to prevent binding
and distortion on breakthrough.
Drilling in Masonry
When drilling in masonry, use high speed carbide-tipped bits. Drilling soft
masonry materials such as cinder block requires little pressure. Hard
materials like concrete require more pressure. A smooth, even flow of
dust indicates the proper drilling rate. Do not let the bit spin in the hole
without cutting. Do not use water to settle dust or to cool bit. Both actions
will damage the carbide.
Driving Screws
When driving screws, use the proper screwdriver bit for your job. After
drilling pilot and shank holes, start the screw slowly and increase the
speed as driving progresses. Set the screw by slowing to a stop. Do not
run screws down at excessive speeds. To remove screws, reverse the
motor.
