and torque to the planned operation.
• Select forward or reverse rotation.
• Use sharp drill bits only.
• Be sure the material to be drilled is anchored or clamped rmly. If drilling thin
material, use a "back-up" block to pr- event damage to the material.
• Always apply pressure in a straight line with the bit. Use enough pressure to keep
the drill bit biting, but do not push hard enough to stall the motor or deed the bit.
• Hold tool rmly to control the twisting action of the drill.
• If DRILL STALLS, it Is usually because it is being overlo- aded. RELEASE TRIGGER
IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO NOT
CLICK TRIGGER OFF AND ON IN AN ATTEMPT TO START A STALLED DRILL- THIS CAN
DAMAGE THE DRILL.
• To minimize stalling as you are breaking through the material, reduce pressure on
drill and ease the bit through the last fractional part of the hole.
• Keep the motor running when pulling the bit back out of a drill hole. This will help
prevent jamming.
• With variable speed drills there is no need to center punch the point to be drilled.
Use a slow speed to start the hole and accelerate by squeezing the trigger harder
when the hole is deep enough to drill without the bit skipping out. Operate at full on
after starting the bit.
• Use twist drill bits, spade bits, power auger bits or hole saws.
• Start drilling with slow speed and increase to full power while applying rm pressure
to the tool
• Holes in wood can be made with the same twist drills used for metal. These bits
may overheat unless pulled out frequently to clear chips from the utes.
• For larger holes, use low speed wood bits.
• Work that is likely to splinter should be backed up with a block of wood.
• Use high speed steel twist drill bits or hole saws.
• Start drilling with slow speed and increase to full power while applying rm pressure
to the tool. A smooth even ow of metal chips indicates the proper drilling rate.
• Use a cutting lubricant when drilling metals. The excep- tions are cast iron and
brass which should be drilled dry.
• NOTE: Large holes 6-10mm in steel can be made easier if a pilot hole or 2mm to
6mm is drilled rst.

DRILLING IN WOOD

DRILLING IN MASONRY (TOOL WITHOUT A HAMMER FEATURE)
• Use carbide tipped bits rated for percussion drilling and be certain that the bit Is
sharp.
• Use a constant and rm force on the tool to drill most effectively. A smooth, even
ow of dust indicates the proper drilling rate.
