Milwaukee Tool 49-66-4716 Insert Bit 1/4 in Drive

Product Description

The MILWAUKEE TOOL 49-66-4716 is a single-end insert bit designed for use with 1/4 inch hex drive power tools and manual bit holders. Machined from steel, this straight-style insert bit measures 1.5 inches in overall length and features a 7/16 inch hex shank for secure tool engagement. It is sold as an individual bit, making it a practical replacement or addition to an existing bit set. HVAC technicians, electricians, and general contractors reach for insert bits like this when working in tight spaces or switching frequently between fastener types on the job.

This insert bit suits a wide range of trade applications including electrical panel work, equipment assembly, and light fixture or device installation. The 1/4 inch drive sizing is compatible with standard quick-change bit holders, impact-rated extension bars, and most cordless screwdrivers and drill/drivers used in the field. Its compact 1.5 inch length keeps the tool profile low in confined work areas where a longer bit would interfere.

Installation Notes

Insert bits are installed and removed by hand from any compatible 1/4 inch quick-change holder or bit tip holder — no tools required for the bit swap itself. Ensure the fastener drive type matches the bit tip before applying torque to avoid cam-out or fastener damage. When using with an impact driver, verify the bit holder is rated for impact use. Inspect the bit for wear or rounding before each use and replace if the drive tip shows visible damage.
