Milwaukee Tool 49-66-0533 Impact Nut Driver Bit Set 10pc

Product Description

The MILWAUKEE TOOL 49-66-0533 is a 10-piece SHOCKWAVE Impact Duty magnetic nut driver bit set designed for use with power impact drivers and drills in professional trade applications. Each bit features a 5/16 inch drive with a 1/4 inch hex shank and measures 2-9/16 inches in overall length. The magnetic tip securely retains fasteners during driving, reducing drop and fumbling in overhead or confined installations. This set is built to withstand the torsional stress generated by impact drivers, making it suitable for repetitive fastener-driving tasks in electrical, HVAC, plumbing, and general construction work.

These impact nut driver bits are used across residential and commercial jobsites wherever hex-head fasteners are driven at volume. Common applications include electrical panel installation, equipment mounting, ductwork assembly, and structural fastening. The 1/4 inch hex shank fits standard quick-change chucks on most impact drivers and drills. The 10-piece pack quantity supports crew-level deployments where multiple tools are in service simultaneously or where replacement bits are kept on hand to avoid jobsite downtime.

Installation Notes

Insert the 1/4 inch hex shank fully into the tool chuck before driving to ensure secure engagement.

Inspect bits for wear or deformation before use and replace any bit showing cracking or mushrooming at the shank. Follow all applicable jobsite safety requirements when operating power tools.
