Milwaukee 49-56-9255 Carbide Hole Cutter 4-1/4 in

Product Description

The Milwaukee Electric Tool Corp 49-56-9255 is a 4-1/4 inch carbide-tipped hole cutter designed for multi-material cutting in demanding trade applications. Part of the Big Hawg line, this cutter uses carbide teeth with an enlarged braze surface for a stronger bond and extended tool life. It is engineered to cut through nail-embedded wood, shingles, cement board, plaster, and other abrasive materials where standard bi-metal hole saws fail prematurely. The optimized slot design speeds plug removal, reducing downtime on the job. A thicker backer plate adds structural support during heavy-duty use. Licensed electricians, plumbers, and general contractors reach for this tool when cutting through mixed or layered materials.

This hole cutter is suited for residential and light commercial installation work where penetrations must pass through wood framing, subfloor assemblies, sheathing, or composite materials that may contain embedded fasteners. It performs in new construction as well as retrofit and remodel scenarios where existing nail patterns are unpredictable. The carbide multi-material pilot bit improves centerpoint accuracy and expands material versatility across a single tool setup.

Key Features

• Carbide-tipped teeth rated for up to 50 times longer life in nail-embedded wood and abrasive materials compared to standard bi-metal cutters
• Capable of cutting 1,000 or more nails without tooth failure under normal use conditions
• Cuts up to 5 times faster than standard hole saws in comparable materials
• Enlarged braze surface creates a stronger mechanical bond between carbide teeth and the cutter body
• Thicker backer plate designed for extreme durability in high-demand applications
• Optimized slot geometry for rapid plug ejection and reduced cutter binding
• Compatible with wood, nails, shingles, cement board, plaster, and similar multi-material substrates

Compatibility

Designed as an OEM-style replacement and standard hole cutter for use with compatible Milwaukee arbor systems and other standard hole cutter arbors accepting 4-1/4 inch carbide hole cutters.

Installation Notes

This tool is installed and operated by licensed electricians, plumbers, HVAC technicians, and general contractors performing penetration work. Ensure the drill or hole cutter arbor is rated for the cutter diameter and the material being cut before starting. Disengage power tools and allow the cutter to come to a complete stop before clearing plugs or inspecting teeth. Follow all applicable OSHA and site safety requirements when working near embedded fasteners or unknown material compositions.
