Screwdriver bit GRAPHITE 56H574 PZ3 1/4" drive, length 150 mm

Graphite 56H574 driver bit PZ3 x 6.35 x 150 mm (1/4") is a Pozidriv screwdriver bit designed for use with hammer drills and impact drivers. The 150 mm length and 1/4" shank make it compatible with standard 1/4" chucks and holders. Manufactured from S2 alloy steel, the bit resists deformation and is intended for repeated heavy-duty use in carpentry, furniture assembly and other applications that demand durability.

Advantages

The S2 alloy steel construction provides good resistance to wear and bending, extending service life during continuous shop work. A long 150 mm shaft gives better reach for deep or recessed fasteners while the standardized 1/4" shank ensures compatibility with most chucks and quick-change holders. The Pozidriv PZ3 tip offers reliable engagement with Pozidriv screws to reduce cam-out.

Suitable for

• Driving and removing Pozidriv (PZ3) screws in carpentry and furniture assembly
• Use with hammer drills, impact drivers and power screwdrivers that accept 1/4" bits
• Working with deeply recessed or hard-to-reach fasteners thanks to the 150 mm length

When it may not be suitable

This bit is specifically shaped for Pozidriv (PZ) screw heads and is not ideal for slotted, Phillips or Torx screws; using it on incompatible fasteners can damage both the screw and bit. It is a single-size tool (PZ3), so tasks requiring different drive sizes will need additional bits. Although made of S2 steel for heavy use, extreme misuse or overload can still cause wear or breakage.

Key specifications

• Drive type: Pozidriv (PZ3)
• Shank diameter: 6.35 mm (1/4")
• Overall length: 150 mm
• Material: S2 alloy steel
• Weight (approx.): 32 g
• Package type: Blister

How to use

Insert the 1/4" shank into a compatible chuck or quick-change holder and secure the bit. Engage the Pozidriv screw head with the PZ3 tip, apply steady pressure and operate the drill or driver at an appropriate speed for the fastener and material. For best results with impact drivers, use controlled bursts rather than continuous high speed. Inspect the tip periodically for wear and replace the bit if the tip becomes rounded.

What to consider before purchase

• Confirm that the screws you use are Pozidriv (PZ) and that PZ3 is the correct size
• Ensure your drill or driver accepts 1/4" (6.35 mm) bits
• Consider whether a set of multiple sizes would better suit varied tasks

Usage recommendations

Use the Graphite 56H574 PZ3 bit for repetitive Pozidriv fastening in wood and furniture work; store it dry and replace when tip wear affects engagement to maintain screw and bit integrity.
