Milwaukee Tool 49-66-0707 Impact Nut Driver Bit Set 7mm

Product Description

The MILWAUKEE TOOL 49-66-0707 is a 10-piece SHOCKWAVE Impact Duty magnetic nut driver bit set designed for use with impact drivers and impact-rated power tools. Each bit drives a 7mm fastener and measures 2.5625 inches in overall length with a 1/4 inch hex shank. The magnetic tip retains nut fasteners during installation, reducing fumbling and drop time on the job. Built to SHOCKWAVE Impact Duty standards, these bits are engineered to handle the torsional stress of high-torque impact drivers. Licensed electricians, HVAC technicians, plumbers, and general trade contractors use this set for rapid fastener driving on panel work, equipment mounting, and structural assembly.

This set fits standard 1/4 inch hex quick-change chucks found on most cordless and corded impact drivers. The 7mm drive size suits metric fasteners common in electrical panel hardware, HVAC equipment enclosures, and imported mechanical assemblies. The 2.5625 inch bit length provides clearance in tight spaces while maintaining rigidity under impact load. Ten identical bits are included, allowing jobsite redundancy or distribution across a crew without purchasing multiple individual units.

Compatibility

Designed for use with 1/4 inch hex quick-change impact drivers. Fits any impact driver or drill accepting a standard 1/4 inch hex shank bit.

Installation Notes

Insert the 1/4 inch hex shank fully into the tool chuck before applying power. Confirm the bit is seated and locked before driving fasteners to prevent cam-out or bit ejection. Impact-rated bits should be used only with impact drivers or impact-rated drills; use in standard drill-drivers may result in premature wear. Inspect bits for cracking or deformation before each use and replace damaged bits immediately.
