BASIC IMPACT DRILL OPERATIONS

9.3 DRILLING WOOD AND PLASTIC

– FIG.9

To prevent splitting around the drill holes on the

reverse side, clamp a piece of scrap timber

under the material to be drilled.

9.4 DRILLING METAL – FIG.10

Metals such as mild steel, aluminium and

brass may be drilled.

– Mark the point to be drilled with a centre

punch

to help the drill bit tip to locate.

– A drop of oil

on the drilled area will aid

cutting and help prolong the life of the bit.

Start drilling at a low speed to prevent the drill

bit from wandering. Once penetration is

achieved, fully depress the trigger to achieve

maximum speed and hammer power.

A correctly fitted dust mask, suitable for the activity

and in accordance to the relevant standard must

be worn.

Swarf produced by metal drilling is extremely sharp.

Take precautions when clearing swarf. The burr left

on the hole is also sharp and should be removed

with a suitable tool.

Always wear safety goggles.

Warning! Drill bit will be hot after use.

Warning! Before drilling check that there are no hidden hazards such as electrical cables, water or

gas pipes running below the surface – use a metal/voltage detector.

Do not expose the drill to either rain or water.
