6-1/2" Spur Auger Bit set, 4 Piece

Milwaukee 48-13-4000 4-Piece 6-Inch Spur Auger Bit Set

The Milwaukee 48-13-4000 Spur Auger Bit Set is engineered for high-speed, clean hole drilling in wood applications commonly encountered in electrical, plumbing, and framing tasks. This 4-piece set includes bits sized 1/2", 3/4", 7/8", and 1", each designed for efficient chip ejection and reduced breakout.

Optimized for use with impact drivers and drill drivers, these auger bits feature double-wing spurs that provide accurate scribing and smooth bore entry. A non-stick coating minimizes friction during operation, helping to maintain consistent feed rates through dimensional lumber and engineered wood materials.

Application Suitability

Designed for wood boring in rough-in work, this bit set is applicable for conduit clearance holes, pipe runs, and general-purpose framing penetrations. Best used in cordless high-torque impact or drill drivers rated for wood drilling. Proper tool RPM and feed control are recommended to maintain optimal hole integrity and bit longevity.
