Main Risks

• Ejection of fragments or swarf due to bit tip breakage or slipping on the screw head.
• Cuts and knocks from tool slippage or loss of control.
• Overheating of the bit after repeated use, with a risk of burns.
• Damage to screws, workpiece or bit holder from using an incorrect size or profile, or excessive torque.
• Ejection of the bit if not properly secured in the bit holder or in the chuck.
• Attraction of metallic particles and possible interference with medical implants when using magnetised bits.
• Electrical hazard when working near live conductors with bits without specific insulation.

Safe Use

• Choose the exact profile and size for the screw head; an accurate match reduces slippage.
• Inspect the bit before use: discard it if you see rounding, cracks, nicks or deformation.
• Fully seat the bit in the bit holder and check it is locked; disconnect the tool or remove the battery when changing bits.
• Clamp or secure the workpiece and keep hands clear of the area of rotation.
• Work at appropriate speed and torque; use the clutch setting if available and apply constant axial pressure, avoiding side loads.
• For impact tools, use only impact-rated bits; do not use standard bits with impact wrenches or impact drivers.
• Wear safety glasses; close-fitting gloves can help prevent cuts, avoiding any loose material that could snag.
• Stop and let the bit cool if it overheats; do not touch it immediately after prolonged use.
• Keep the bit and magnet free of swarf and dust to improve grip and reduce slippage.

Storage and Maintenance

• Store bits clean and dry in their case to prevent corrosion and knocks.
• Clean after each use by removing metal filings and dirt; dry thoroughly if they have been exposed to moisture.
• Organise by type and size to avoid mix-ups and damage to the drive profiles.
• Do not sand, grind or modify the geometry of the bit; this can weaken it and increase the risk of breakage.
• Remove from service any bits with visible wear, chipped edges, or that do not seat firmly in the screw.
• Keep magnetised bits away from devices sensitive to magnetic fields and from objects that could be attracted inadvertently.

Restrictions of Use

• Do not use bits for prying, striking, drilling or as a punch; they are designed solely for driving screws.
• Do not work on energised circuits unless the bit and the tool are specifically insulated and rated for it.
• Keep bits and tools out of the reach of children and people unfamiliar with their use.
• When working at height, use bit and screw retention systems to prevent dropped objects.
• People with electronic implants should keep their distance from magnetised bits and bit holders and avoid placing them near the chest.
