Milwaukee Impact Driver Bit 48-32-4601 1 Inch Number 2 Phillips (1/4 Hex Shank PH2 Custom Alloy76 Steel Heavy Duty Fastening 5 Pack)

Milwaukee 48-32-4601 SHOCKWAVE Impact Duty 1-Inch #2 Phillips Insert Bit 5-Pack

The Milwaukee 48-32-4601 is a 5-piece set of 1-inch #2 Phillips insert driver bits engineered with a 1/4-inch hex shank for high-torque fastening into wood, sheet metal, and plastic substrates. Constructed from proprietary Custom Alloy76 steel and subjected to a customized heat treatment process, this Impact Duty driver bit set delivers up to 50 times extended wear life compared to standard competitive impact bits. Featuring an optimized Shockzone geometry that flexes to absorb peak rotational torque shock alongside a Wear Guard Tip profile that prevents fastener head cam-out, these 1-inch bits provide solid shank stability for commercial contractors driving framing screws and timber fasteners with cordless impact drivers.

Best Used For:

• Commercial Wood Framing & Sheathing: Driving high-torque structural wood screws and framing fasteners into timber studs without rounding screw recesses.
• Sheet Metal & Mechanical Fastening: Fastening self-drilling sheet metal screws into HVAC ductwork and steel framing studs using cordless impact drivers.
• Electrical & Interior Fixture Mounting: Securing junction boxes, switch plates, and interior architectural hardware using #2 Phillips wood and machine screws.

Key Performance & Safety Features

• 50X Extended Life Custom Alloy76 Steel: Proprietary heat-treated alloy steel construction resists severe impact loads and outlasts standard driver bits by 50 times.
• Torque-Absorbing Optimized Shockzone: Tailored shank flex geometry absorbs rotational torque spikes to redirect stress away from the tip and prevent head snapping.
• Wear Guard Tip Precision Fitment: Precision-milled tip profile protects fastener recess fit over the full working life of the bit to eliminate cam-out and stripping.
• Laser-Etched Size Identification: High-contrast permanent size markings allow instant bit size verification in storage rails, pouches, and tool bags.
• Universal 1/4-Inch Hex Shank Base: Standardized 1/4-inch hex base fits securely into magnetic bit extension holders, quick-change adapters, and drill chucks.
• High-Torque Impact Driver Rating: Engineered specifically to withstand the aggressive pulse frequency of corded and cordless high-rpm impact drivers.

What's Included

• (5) Milwaukee SHOCKWAVE Impact Duty 1" #2 Phillips (PH2) Insert Bits (48-32-4601)

Technical Specifications

Pro-Tip: Seat the 1-inch insert bit fully inside a magnetic bit holder before driving to ensure the #2 Phillips Wear Guard tip aligns squarely in screw head recesses and prevents off-axis slippage.
