Milwaukee 48-32-4441 Ecx Insert Bit 1 Inch 2 Pack

Product Description

The MILWAUKEE 48-32-4441 is a SHOCKWAVE ECX insert bit designed for use with ECX-compatible fasteners in professional trade applications. Manufactured from heat-treated steel, this bit measures 1 inch in overall length and is sold in a 2-pack. The ECX drive type combines a Phillips and square recess profile, reducing cam-out during high-torque driving. Electricians, plumbers, and general contractors reach for insert bits like this when working with power drivers and impact-rated tool setups where bit longevity and drive security matter.

This bit is suited for light-gauge fastening tasks common in electrical, plumbing, and mechanical trade work. The 1-inch insert length fits standard bit holders and quick-change chucks used with drills and impact drivers. The 2-pack format supports continuous workflow on the job site without stopping to locate a replacement. ECX bits are particularly useful when working with fasteners found in electrical panels, enclosures, and equipment covers that use the combined Phillips-square recess profile.

Key Features

• ECX drive type combines Phillips and square recess profiles to reduce cam-out
• Heat-treated steel construction for durability under repeated impact loads
• 1-inch overall length fits standard quick-change bit holders
• SHOCKWAVE series rated for impact driver use
• 2-pack format reduces downtime from bit wear on the job

Compatibility

Installation Notes

Insert bits are installed and removed by hand or with a magnetic bit holder — no tools required for bit changes. Ensure the power driver is powered off or the battery is removed before swapping bits. Use only with fasteners that match the ECX Number 1 drive profile to avoid fastener or bit damage. Follow applicable trade codes when driving fasteners in electrical or mechanical assemblies.
