Screwdriver bit set Irwin impact PH2 x 89 mm, 2 pieces

Irwin impact PH2 x 89 mm screwdriver bits, set of 2, are designed for use with impact drivers and powered screwdrivers. Each bit features a PH2 (Phillips) tip with standardized geometry and an 89 mm shaft length that reaches deeper or recessed fasteners while maintaining torsional strength required for impact applications. The set offers two identical bits for replacement during prolonged jobs or for use in multiple tools.

Advantages

The bits are manufactured to deliver consistent fit in Phillips cross-head screws and resist cam-out under impact loads. The 89 mm shaft provides extended reach without sacrificing control, and the impact-rated material and heat treatment improve durability under repeated high-torque cycles. Supplied as a pair, the set reduces downtime by providing a spare bit when one becomes worn.

Suitable for

• Installation of Phillips-head screws in wood, drywall, and metal fixtures
• Assembly work in construction and joinery where recessed screws are used
• Maintenance and repair tasks requiring impact-rated screwdriver bits

Key specifications

• Tip type: PH2 (Phillips)
• Shaft length: 89 mm
• Quantity: 2 pieces
• Compatibility: impact drivers and power screwdrivers with standard bit holder
• Material/finish: impact-rated steel with heat-treated tip (manufacturer standard)

How to use

Insert the bit securely into the driver’s quick-change chuck or magnetic bit holder until it locks. Select a suitable torque setting on the impact driver for the screw and material to avoid overdriving. Position the PH2 tip squarely in the screw head before applying power, and use steady, controlled bursts with an impact driver. Replace bits when the tip shows signs of wear or rounding to maintain proper engagement and avoid screw damage.

Usage recommendations

For best results, use these Irwin PH2 x 89 mm impact bits with appropriately sized Phillips screws and matched torque settings on the impact driver. Store spare bits in a tool case to avoid tip damage and inspect tips regularly when performing heavy-duty or repetitive fastening tasks.
