Milwaukee Tool 49-57-8649 Hole Saw 4-1/2 in Carbide Tipped

Product Description

The MILWAUKEE TOOL 49-57-8649 is a carbide-tipped hole saw designed for cutting through metal, steel, and aluminum. It features a 4-1/2 inch saw diameter and a 3/16 inch cutting depth, making it suited for sheet metal work, conduit knockouts, and panel penetrations. The toothed cutting edge delivers clean, repeatable cuts in demanding trade applications. This hole saw is built for electricians, HVAC techs, plumbers, and other trade professionals who require consistent performance when cutting through ferrous and non-ferrous materials on the job.

The 49-57-8649 is intended for use in metal fabrication and field installation scenarios where a precise, large-diameter hole is needed in sheet metal, steel enclosures, aluminum panels, or similar materials. It is a practical fit for electrical knockout work, HVAC duct penetrations, and plumbing rough-in applications where clean hole geometry matters. The carbide-tipped construction supports repeated use across multiple cuts without the rapid dulling seen with standard bi-metal saws.

Key Features

• 4-1/2 inch saw diameter for large-format hole cutting in metal applications
• 3/16 inch cutting depth suited for sheet metal, panels, and thin stock
• Carbide-tipped construction for extended cutting life versus bi-metal alternatives
• Toothed cutting edge delivers controlled, clean cuts through metal, steel, and aluminum
• Compatible with standard arbor setups used in trade drill configurations

Compatibility

Designed as an OEM-style replacement hole saw for use with standard hole saw arbors in professional trade drilling applications involving metal, steel, and aluminum substrates.

Installation Notes

Installation and use of this hole saw should be performed by a qualified trade professional familiar with rotary cutting tools and applicable safety codes. Secure the workpiece firmly before cutting and ensure the arbor is properly seated and tightened before operation. Use appropriate cutting fluid or lubricant when cutting steel to extend blade life and reduce heat buildup. Always wear appropriate PPE including eye protection and gloves when operating hole saws in metal applications.
