Milwaukee 49-56-0183 Bi-metal Hole Saw 3-1/4 in

Product Description

The MILWAUKEE 49-56-0183 is a 3-1/4-inch bi-metal hole saw designed for general-purpose cutting in metal, wood, and composite materials. The saw runs a 3.5 TPI tooth geometry engineered to extend tooth life in metal applications. A thermoset coating reduces heat buildup during the cut, which is especially useful when running cordless tools where battery efficiency matters. ALL-ACCESS SLOTS are machined into the body to allow faster plug removal, reducing downtime between cuts on production jobs. This is a hand tool accessory installed by electricians, plumbers, HVAC technicians, and general contractors.

This hole saw is suited for residential and light commercial applications where 3-1/4-inch bored penetrations are required — conduit knockouts, pipe pass-throughs, HVAC duct penetrations, and structural framing rough-ins. The thermoset coating is optimized to deliver extended run time when paired with cordless platforms, making it a practical choice for field work where a compressor or corded tool is not available. Manufactured in the USA.

Key Features

• 3.5 TPI tooth design engineered for extended life in metal cutting applications
• ALL-ACCESS SLOTS allow faster plug removal and reduce downtime between holes
• Enlarged slot design improves pilot bit visibility for accurate hole placement
• Faster chip ejection keeps the cut zone cooler during extended use

Compatibility

Designed as an OEM-style general-purpose bi-metal hole saw for use with standard arbor systems compatible with 3-1/4-inch hole saw bodies.

Installation Notes

Hole saw installation and use should be performed by qualified tradespeople familiar with rotary cutting tools and applicable safety codes. Secure the workpiece before drilling and ensure the arbor and pilot bit are properly seated and locked before operation. Keep cutting speeds appropriate for the material being cut to avoid premature tooth wear or overheating. Disconnect power from the drill or driver before changing the hole saw or removing a plug.
