Milwaukee Elec Tool 48-32-4572 Square Power Bit 3.5 in No. 2

Product Description

The MILWAUKEE ELEC TOOL 48-32-4572 is a 3.5-inch No. 2 Square power bit designed for fastening and impact fastening applications in trade and production environments. Sold in a 3-pack, it is built from Custom Alloy76, a proprietary steel formulation with a heat treatment process matched to the specific tip type. The Shockzone geometry is optimized for each tip type and length to absorb peak torque and reduce breakage risk during high-stress driving. The Wear Guard Tip extends service life by protecting the drive fit from wear over repeated use cycles. Licensed electricians, plumbers, and general contractors commonly run this bit in impact drivers on rough-in and fixture work.

This bit is suited for residential and commercial construction and service work where No. 2 square drive fasteners are specified. The 3.5-inch length provides added reach in tight framing bays, electrical panels, and cabinet installations. The 3-pack quantity supports ongoing production use where bit wear is a routine consumable cost. It is an appropriate choice for trades using impact drivers on wood screws, subpanel covers, and similar square-drive hardware.

Key Features

• Custom Alloy76 construction with proprietary heat treatment matched to tip geometry for maximum strength
• Shockzone optimized per tip type and length to absorb peak torque and reduce breakage
• Wear Guard Tip protects drive fit geometry over extended use cycles
• Forged tip design for maximum grip on No. 2 square drive fasteners
• 3.5-inch length for extended reach in confined installation areas
• Sold as a 3-pack for continuous production or service use

Compatibility

Designed as an OEM-style replacement and standard-use bit compatible with impact drivers and drills accepting standard 0.25-inch hex shank power bits requiring a No. 2 square drive tip.

Installation Notes

This bit is installed and used by electricians, plumbers, carpenters, and other trades operating impact drivers or drill drivers. Inspect the drive tip before each use and replace if the fit geometry shows visible wear to avoid cam-out damage to fastener heads. Do not apply lateral force to the bit during driving, as side-loading accelerates tip wear and increases breakage risk. Follow the tool manufacturer guidelines for maximum RPM and torque settings appropriate for the fastener and substrate.
