Screwdriver bit GRAPHITE 56H505, Pozidriv PZ3, 1/4" drive, 25 mm length

GRAPHITE impact bits type PZ3, total length 25 mm, are heavy-duty screwdriver bits intended for demanding fastening tasks with high torque using screwdrivers or impact drivers. Manufactured from high-quality S2 steel, the bit features a torsion zone that deforms under load to reduce peak forces transferred to the tip, increasing resistance to breakage and extending service life. The Pozidriv PZ3 working tip provides secure engagement with compatible screws.

Advantages

The S2 steel construction offers increased flexibility and improved mechanical damage resistance. The built‑in torsion zone absorbs shock and high torque peaks, lowering the risk of tip fracture and lengthening operational life. Precise PZ3 geometry ensures reliable fit and reduces cam‑out during driving.

Suitable for

• Furniture assembly and fitting
• Joinery and carpentry fastening
• General fastening with cordless or electric screwdrivers and impact drivers

Key specifications

• Tip type: Pozidriv PZ3
• Drive system: 1/4" hex shank
• Total length: 25 mm

How to use

Insert the 1/4" hex shank into a compatible bit holder or screwdriver chuck. Select the correct PZ3 bit size for the Pozidriv screws to ensure proper engagement. Apply steady pressure and drive at suitable speed; when using an impact driver, allow the torsion zone to absorb torque spikes. Inspect the tip for wear before reuse and replace if deformed or rounded.

Usage recommendations

The bit is intended for heavy duty fastening; use the correct PZ3 Pozidriv screws and avoid excessive side load. Store in a blister pack or bit organizer to protect the tip and extend service life.
