Maintenance; Specifications - DeWalt DCD996 Instruction Manual

- To minimize stalling or breaking through the
material, reduce pressure on drill and ease the bit
through the last fractional part of the hole.
• Large holes (5/16" to 1/2" [7.9 mm to 12.7 mm]) in steel
can be made easier if a pilot hole (5/32" to 3/16" [4 mm
to 4.8 mm]) is drilled first.
• If drilling thin material or material that is prone to
splinter, use a wood "back-up" block to prevent damage
to the workpiece.
Hammerdrilling
IMPortANt: Use carbide-tipped or masonry bits rated for
percussion drilling only.
1. Select the desired speed/torque range using the speed
6
selector to match the speed and torque to the
planned operation. Turn the mode selection collar
the hammerdrill symbol.
2. Pull the trigger, applying just enough pressure on the
hammer to keep it from bouncing excessively or "rising"
off the bit.
recommendations for Hammerdrilling
• Too much force will cause slower drilling speeds,
overheating, and a lower drilling rate.
• A smooth even flow of material indicates the proper
drilling rate.
• Drill straight, keeping the bit at a right angle to the work.
Do not exert side pressure on the bit when drillling as
this will cause clogging of the bit flutes and a slower
drilling speed.
• When drilling deep holes, if the hammer speed starts to
drop off, pull the bit partially out of the hole with tool still
running to help clear debris from the hole.
