7. Selecting the appropriate drill bit:
When boring concrete or stone
Use the drill bits specified in the Optional Accessories.
When boring metal or plastic
Use an ordinary metalworking drill bit.
Sizes range from a minimum of 1/16" (2mm) to chuck maximam capacity.
When boring wood
Use an ordinary woodworking drill bit.
However, when drilling 1/4" (6.5 mm) or smaller holes, use a metalworking drill bit.
8. Mounting and dismounting of the bit
For keyless chuck
(1) Mounting the bit
After inserting a driver bit, etc. into the keyless drill chuck, firmly grasp the ring and
tighten the sleeve by turning it toward the right (in the clockwise direction as viewed
from the front). (See Fig. 2)
If the sleeve becomes loose during operation, tighten it further. The tightening force
becomes stronger when the sleeve is tightened.
(2) Dismounting the bit
Firmly grasp the ring and loosen the sleeve by turning it toward the left (in the
counterclockwise direction as viewed from the front). (See Fig. 2)
NOTE:
When the sleeve does not become loose any further, fix the side handle to the sleeve.
Then, strike the grip of the side handle to the left in order to loosen the sleeve, while
holding the ring by hand. (Fig. 3)

CAUTION:
Do not fix the side handle to the ring of the keyless chuck because of a risk that doing
so may damage the ring.

chuck wrench to secure it, tightening the
chuck by each of the three holes in turn.
