Screwdriver Bit MILWAUKEE PH1 90 mm Shockwave — single piece

The MILWAUKEE Shockwave PH1 screwdriver bit, 90 mm length, single piece is designed for Phillips PH1 fastening tasks. Manufactured for use with impact drivers and cordless screwdrivers, this bit delivers the correct PH1 geometry for reliable engagement with cross-head screws in wood, metal and composite materials. Its 90 mm overall length provides extra reach in recessed or hard-to-access screw positions while the Shockwave design improves durability under high-torque and impact conditions.

Advantages

The Shockwave profile and heat-treated steel construction enhance resistance to wear and reduce cam-out during driving. A single-piece format ensures consistent torque transfer and minimizes breakage points compared with multi-component adapters. At 90 mm length the bit offers improved access for deeper countersinks or tight assemblies without sacrificing control or fit in common 1/4" hex chucks.

Suitable for

• Driving Phillips PH1 screws in woodworking projects
• Fastening hardware in metal sheet and light-gauge applications
• Assembly and repair tasks on cabinets, furniture and fixtures
• Use with cordless impact drivers and screwdrivers for professional and DIY jobs

Key specifications

• Tip type: Phillips PH1
• Overall length: 90 mm
• Design: Shockwave impact-rated bit geometry
• Material: Heat-treated tool steel for enhanced toughness
• Drive connection: 1/4" hex shank compatible with standard chucks and quick-change holders
• Packaging: single piece

How to use

Insert the 1/4" hex shank into the driver or quick-change holder until it locks. Select the appropriate speed or torque setting on your impact driver or cordless screwdriver for the screw and material being used. Position the PH1 tip in the screw recess, apply steady axial pressure and drive the screw at controlled speed. For deep or recessed screws, the 90 mm length allows you to reach the fastener without extensions. Inspect the bit regularly for wear and replace it if the tip becomes rounded or damaged to maintain secure engagement and avoid screw head damage.

Usage recommendations

Use the bit with impact-rated drivers when applying high torque and avoid excessive side-loading. For optimal life, match the bit size precisely to the screw head and replace the bit when signs of wear appear.
