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