Inserting and removing bits
These drills have a keyless chuck, which means that a chuck key is not needed to secure a bit in the drill.
Open the chuck by holding the chuck collar and unscrewing the chuck in an anti-clockwise direction.
Do this sufficiently enough to allow the drill bit to enter the jaws of the chuck.
Ensure the bit is fully inserted, so that the chuck jaws grip the straight section of the bit.
While holding the chuck collar in place, rotate the chuck clock-wise until the jaws tighten on the bit. The chuck
needs to be tightened firmly to ensure the bit is held securely.
To remove the bit, hold the chuck collar while rotating the chuck sharply in an anti-clockwise direction,
sufficiently enough to allow the bit to be removed.
Drilling
Drilling metals
• Always clamp sheet metal.
• Support thin metal with a block of wood to avoid distorting it.
• Use a punch to mark the centre of the hole.
• Use a suitable lubricant for the material you are working on.
Use OIL when drilling into STEEL.
Use TURPENTINE or PARAFFIN when drilling into ALUMINIUM
Do not lubricate Brass, copper or cast iron
Drilling plastics and plastic coated chipboard
• Use high speed drill bits
• See drilling wood below
Drilling wood
• Clamp a piece of scrap wood to the back of your work to prevent splintering .
All drilling operations
• Mark off the centre of the hole using a centre punch or nail.
• Don't force the drill, let it work at its own pace
• Keep the drill bit sharp.
• Reduce pressure, as the drill is about to break through the item being drilled.
Chuck replacement
The chucks of reversible drills are always fixed by a screw with a left-hand thread. The screw, which is located in
the centre of the chuck, must be removed before the chuck can be removed. To remove the screw, turn it in a
clockwise direction. The chuck can now be removed by unscrewing it anti-clockwise. If you have trouble
removing the chuck take the drill to your nearest authorised tool service centre for chuck replacement.
CAUTION. Always ensure that the drill is switched off and the battery pack is removed before making any
adjustments.
