Open or close the keyless chuck (1) to a point where the opening is slightly
larger than the drill bit you intend to use.

does not touch the screw inside the keyless chuck (1).
•
Tighten the keyless chuck (1) onto the drill bit as described above.

General Hints for Drilling in all Materials
•
Always use sharp drill bits.
•
Mark the place where you would like the hole to be drilled.
•
Commence with a slow rotation speed to start the hole.
•
Reduce your pressure on the drill when the drill bit is about to break through
the material.
Metal Drilling
•
Support thin material with a wooden plate.
•
Use a punch to mark the position of the hole.
•
If drilling a large hole, use a small drill first to establish a pilot hole then use the
required large size drill bit.
•
Use only HSS (high speed steel) drill bits or those recommended for metal use.
•
When drilling into iron or steel, use a cooling lubricant such as thin oil. With
aluminium, use turpentine or paraffin. With brass, copper and cast iron, use no
lubricant but withdraw the drill regularly to assist cooling.
Wood Drilling
•
Mark the place where you want to drill with a punch or a nail.
•
To avoid splintering on breakthrough either clamp a piece of scrap wood to the
back of the wood or continue the hole from the back of the wood when the
drill bit first breaks through.
