Metal Drilling (Normal Drilling Mode)
For maximum performance, use high-speed steel bits for metal or steel drilling, and set the
tool to Normal 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.
–
Masonry Drilling
For maximum performance, use carbide-tipped masonry bits when drilling holes in brick,
concrete, etc and set the tool to Rotary Hammer Mode
a. Maintain a speed and a pressure that allow cutting without overheating the bit or Drill.
Applying too much pressure will:
Overheat the drill.
–
Wear the bearings.
–
Bend or burn bits.
–
Produce off-center or irregular-shaped holes.
–
b. Apply light pressure and medium speed for best results in brick.
c. Apply additional pressure for hard materials such as concrete.
d. When drilling holes in tile, practice on a scrap piece to determine the best speed and
pressure. Set the tool to Normal Drilling Mode.
e. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
