Milwaukee 48-00-5221 Ship Auger Bit 9/16 in 18 in

Product Description

The MILWAUKEE 48-00-5221 is a ship auger bit designed for drilling deep, clean holes in wood and wood-based materials. With a 9/16-inch cutting diameter and an 18-inch overall length, this bit handles through-the-stud and rough-framing boring tasks that shorter spade or twist bits cannot reach. A 15-inch flute length clears chips efficiently during deep-bore operations, reducing bind-up and heat buildup. It is typically used by electricians, plumbers, and carpenters who need to run conduit, pipe, or wire through framing members in tight or deep-clearance situations.

This ship auger bit suits residential and light commercial rough-in work where long-reach boring through dimensional lumber, engineered wood, or stacked framing members is required. It is compatible with standard 7/16-inch hex-shank drill chucks and right-angle drills commonly used in trade applications. The 9/16-inch diameter is a common size for low-voltage wire runs and smaller conduit or pipe penetrations through wood framing.

Key Features

• 9/16-inch cutting diameter for low-voltage and small-diameter pipe or conduit penetrations
• 18-inch overall length provides extended reach through deep framing assemblies
• 15-inch flute length promotes aggressive chip evacuation during deep boring
• Designed for wood and wood-based materials including framing lumber
• Compatible with standard 7/16-inch hex-shank chuck systems used in trade drills

Compatibility

Designed as an OEM-style ship auger bit suitable for use with standard 7/16-inch hex-shank right-angle drills and corded drill drivers used in electrical, plumbing, and carpentry rough-in applications.

Installation Notes

Ship auger bits are installed by electricians, plumbers, and carpenters during rough-in phases before drywall. Always confirm the bore path is clear of energized wiring, gas lines, and structural fasteners before drilling. Use a right-angle drill or extended drill driver for confined framing bays. Allow the bit to clear chips by backing out periodically on deep passes to prevent binding and overheating.
