Hints for optimum use
Drilling
Always apply a light pressure in a straight line with the drill
u
bit.
Just before the drill tip breaks through the other side of the
u
workpiece, decrease pressure on the tool.
Use a block of wood to back up workpieces that may
u
splinter.
Use spade bits when drilling large diameter holes in wood.
u
Use HSS drill bits when drilling in metal.
u
Use masonry bits when drilling in soft masonry.
u
Use a lubricant when drilling metals other than cast iron
u
and brass.
Make an indentation using a centre punch at the centre of
u
the hole to be drilled in order to improve accuracy.
Screwdriving
Always use the correct type and size of screwdriver bit.
u
If screws are difficult to tighten, try applying a small
u
amount of washing liquid or soap as a lubricant.
Always hold the tool and screwdriver bit in a straight line
u
with the screw.
