Main hazards

• Cuts when handling sharp tips and cutting edges.
• Projection of fragments, chips and dust when drilling; possible drill bit breakage due to wear or misuse.
• Overheating of the bit and workpiece, with risk of burns and premature bit failure.
• Binding that can cause sudden drill kickback and loss of control.
• Entanglement of loose clothing, loose gloves or hair with the rotating bit.
• Damage to hidden cables, pipes or other services when drilling walls or floors.
• Sparks when working metal near flammable materials.

Safe use

• Choose a drill bit suitable for the material and compatible with the chuck; do not use one type of bit on a material it is not designed for.
• Inspect before use: discard bits that are bent, chipped, cracked or with a worn shank.
• Insert the bit fully into the chuck and tighten securely; remove the chuck key before starting.
• Secure the workpiece with a vice or clamps and clear the drilling area.
• Wear eye protection; use a dust mask when drilling materials that generate fine dust (e.g. brick, concrete or tile), and hearing protection where appropriate.
• Maintain a stable stance and hold the drill firmly; avoid applying lateral force to the bit.
• Work at moderate speed and pressure; let the bit cut. Take breaks to cool and, when drilling metals, use lubrication where recommended.
• Do not touch the bit immediately after use; it may be very hot.
• Use the hammer function only with suitable masonry bits.
• Before drilling, check for cables, pipes or other hidden services in the area.

Storage and maintenance

• Clean the bits after use, remove chips and dust, and dry them thoroughly.
• Protect them against corrosion with a light film of oil where appropriate.
• Store them in their case or rack to prevent them knocking against each other and to protect tips and cutting edges.
• Allow them to cool completely before storing.
• Check periodically for wear and damage; replace dull, bent or cracked bits.
• Sharpen only if you know the procedure; otherwise replace them or use a sharpening service to avoid damage.
• Keep the storage area dry and away from moisture and corrosive agents.

Restrictions of use

• Keep out of reach of children; not a toy.
• Do not use while wearing loose clothing, dangling jewellery or loose gloves during drilling; tie back long hair.
• Do not use on materials or diameters for which the bit is not designed; do not force it or use it as a lever.
• Do not modify, weld or grind the shank or cutting edges.
• Do not use drill bits as punches, chisels or other impact tools.
• Do not work near flammable gases, liquids or dust when sparks may be produced.
• Avoid use if you are fatigued or under the influence of alcohol or substances that reduce alertness.
