Milwaukee 48-13-6120 Ship Auger Bit 1-1/8 Inches

Product Description

The Milwaukee Electric Tool Corp 48-13-6120 is a ship auger bit designed for boring large-diameter holes through structural lumber, timbers, and framing members. At 1-1/8 inches in diameter and 18 inches in length, this bit handles deep-penetration drilling tasks that standard spade or brad-point bits cannot accommodate. It is built for use in a heavy-duty corded or cordless drill and is sized for applications where clearance holes for pipes, conduit, cables, and fasteners must pass through thick wood sections. Carpenters, electricians, plumbers, and HVAC technicians reach for ship auger bits when routing through floor joists, wall plates, and rim boards on both new construction and retrofit work.

This bit is suited to residential and light commercial construction and remodeling scenarios. Electricians use ship auger bits to bore through stacked plates and joists when running branch circuits or service cable. Plumbers use them for drain and supply runs through framing. HVAC technicians use them for refrigerant line sets and low-voltage control wiring. The 18-inch length provides the reach needed to clear deep framing sections without extension attachments in most standard applications.

Key Features

• 1-1/8 inch cutting diameter for large clearance holes in structural lumber
• 18-inch overall length provides deep-reach boring capability through thick framing
• Ship auger geometry with a lead screw tip for self-feeding and controlled entry
• Compatible with standard heavy-duty corded and cordless drill chucks
• Sold in a package of 8 units per case for job-site stocking

Compatibility

Designed as an OEM-style replacement and standard-use ship auger bit suitable for use with heavy-duty corded or cordless drills accepting standard hex or round shank auger bit shanks in construction and trade applications.

Installation Notes

Ship auger bits are installed and removed by hand into the drill chuck — ensure the chuck is fully tightened before drilling. Verify that the drill speed setting is appropriate for large-diameter boring in wood to avoid binding or overloading the tool motor. When boring near electrical wiring, plumbing, or structural fasteners, confirm the drilling path is clear before applying feed pressure. Follow applicable local codes, including NEC requirements for cable protection through framing where applicable.
