DRILLING WOOD (ROTARY DRILLING MODE)
(FIG. 12)
For maximum performance, use high-speed
steel or brad-point bits for wood drilling, and set
the mode selector to the rotary drilling mode .
a. Begin drilling at a very low speed to prevent
the bit from slipping off the starting point.
b. Increase speed as the drill bit bites into the
material.
c. When drilling “through” holes, place a block of
wood behind the workpiece to prevent ragged
or splintered edges on the back side of the
hole (Fig. 12).
NOTICE: Bits may overheat unless pulled out
frequently to clear chips from flutes.
DRILLING METAL
(ROTARY DRILLING MODE)
For maximum performance, use high-speed
steel bits for drilling metal or steel, and set the
mode selector to the rotary drilling mode .
a. When drilling metals, use light oil on the drill
bit to keep it from overheating. The oil will
prolong the life of the bit and increase the
drilling action.
b. Begin drilling at a very low speed to prevent
the bit from slipping off the starting point.
c. Maintain a speed and a pressure that allow
cutting without overheating the bit. Applying
too much pressure will:
–
Overheat the drill.
–
Wear the bearings.
–
Bend or burn bits.
–
Produce off-center or irregularly shaped holes.
DRILLING TILE (ROTARY DRILLING MODE)
For maximum performance, use high-speed
steel bits for drilling in tile, and set the mode
selector to the rotary drilling mode.
a. When drilling holes in tile, practice on a
scrap piece to determine the best speed and
pressure. Set the tool to rotary drilling mode.
b. Applying adhesive tape to the drilling site can
reduce slipping and cracking.
c. Begin drilling at a very low speed to prevent
the bit from slipping off the starting point.
