Screwdriver impact bit Irwin PH2 x 89 mm, single piece

Irwin PH2 x 89 mm impact screwdriver bit is a single-piece driver bit designed for use with impact drivers and hammer drills. The PH2 Pozidriv/Phillips tip and 89 mm overall length provide a compact replacement bit for tightening and loosening screws in wood, metal and common construction materials. The bit is intended for professional and DIY fastening tasks where an impact-rated tip is required.

Advantages

This single-piece Irwin bit offers a hardened tip for improved wear resistance and consistent engagement with PH2 screws. Its 89 mm length balances reach and control, allowing access to recessed fasteners while remaining compact enough for confined spaces. The impact rating ensures the bit withstands repeated blows from impact drivers without premature fracturing, offering reliable performance for repetitive fastening operations.

Suitable for

• Driving PH2 Pozidriv/Phillips screws in wood and timber assemblies
• Fastening metal sheets and light-gauge metal components with PH2 screws
• General construction and repair tasks using impact drivers or hammer drills
• DIY projects and professional trade work where a single, durable PH2 bit is needed

When it may not be suitable

The bit is a standard PH2 profile and may not fit non-standard screw heads, tamper-proof fasteners, or larger-sized Phillips/Pozidriv screws. For precision electronics work or very small screws this 89 mm impact bit is oversized and not appropriate. Extremely high-torque industrial applications that require specialised alloy or longer custom bits may require a different bit type.

Key specifications

• Tip type: PH2 (Pozidriv/Phillips compatible)
• Length: 89 mm overall
• Construction: single-piece impact-rated bit
• Intended use: impact drivers and hammer drills
• Suitable materials: wood, metal, common construction materials

How to use

Insert the hex shank end securely into the chuck or bit holder of an impact driver or hammer drill. Align the PH2 tip with the screw head and apply steady axial pressure while operating the driver at appropriate speed and torque settings for the material. Use short bursts when starting screws in hard materials to avoid cam-out. Replace the bit when signs of rounding, chipping, or excessive wear appear to maintain safe and efficient fastening.

What to consider before purchase

• Confirm screw head compatibility with PH2 profile
• Check that 89 mm length meets reach and clearance requirements
• Ensure your tool accepts standard hex-shank impact bits

Usage recommendations

Use with a suitably rated impact driver and appropriate torque settings. Store the bit in a holder or pouch to protect the tip and inspect regularly for wear; replacing worn bits improves screw retention and reduces risk of damage to screw heads and workpieces.
