The 30" extension tube MUST be used when attaching the 33° Angle
Drive. The extension tube can optionally be used with the Right Angle
Drive.
1.
Remove the chuck from the drill (see "Removing the Chuck From the
Drill").
2.
Slide extension tube over drill collar and tighten clamp securely.
3.
Slide auxiliary side handle onto 30" extension tube and secure.
4.
Insert drive shaft through 30" extension tube.
5.
Engage hex nut with hex drive on drill.

1.
Attach 33° angle drive by inserting hex drive into hex socket in

Selecting Bits
When selecting a bit, use the right type for your job. For best perfor-
mance, always use sharp bits.
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. Use low speeds for
plastics with a low melting point.
NOTE: Keep the speed low enough to prevent burning the bit.
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.

Double

sleeve
1.
Remove the chuck from the drill (see "Removing the Chuck From the
Drill"). Slip the double hex coupling over the hex on the drill spindle.
Loosen the clamping screws on the clamping sleeve and slip the
sleeve onto the drill collar.
2.
Slide the Right Angle Drive head 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.
NOTE: Attaching the drill chuck to the side marked "LOW" reduces
the speed by 1/3, or 33%. Attaching the drill chuck to the opposite
side increases the speed by 50%.
3.
When assembled, turn the Right Angle Drive head to the desired
position and tighten the clamping screws to secure the unit. Thread
the chuck onto the Right Angle Drive spindle. INSTALL CHUCK
LOCKING SCREW.
Attaching Right Angle Drive to 30" Extension Tube
1.
Attach right angle drive by inserting spindle hexagon into hex socket
in extension drive shaft. Secure with clamp.
2.
Thread the chuck onto the right angle drive spindle. INSTALL CHUCK
LOCKING SCREW.
Removing the Chuck From Angle Drive Units (Fig. 7)
The chuck can be removed from the angle drive unit in the same manner
it is removed from the drill; however, ALWAYS REMOVE 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 angle drive spindle before attempting to loosen the chuck.
APPLICATIONS
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. Do not
attempt to drill through steel reinforcing rods. Both actions will damage
the carbide.
