Milwaukee Elec Tool 49-56-0233 Bi-metal Hole Saw 4-1/2 in

Product Description

The MILWAUKEE ELEC TOOL 49-56-0233 is a 4-1/2 inch bi-metal hole saw engineered for heavy-duty cutting through wood, metal, and plastic. The 3.5 TPI tooth geometry is designed to extend blade life in metal applications, where heat and wear typically shorten saw longevity. Bi-metal construction bonds a high-speed steel cutting edge to a flexible alloy steel body, resisting tooth breakage under load. The Thermoset Coating on the body reduces friction during the cut, allowing faster penetration and optimized performance when running on cordless platforms. This saw is manufactured in the USA and ships as a package of two units.

This hole saw is suited for residential and commercial trade work where repeated cuts through structural steel, conduit knockout applications, wood framing, and plastic enclosures are required. Electricians, plumbers, and HVAC technicians will find it appropriate for drilling clean, accurately sized holes in panels, junction boxes, and building materials. The ALL-ACCESS SLOTS cut into the cup body allow a flat tool to break the plug free without removing the saw from the drill, reducing downtime between holes. The open slot geometry also improves sightlines to the pilot bit for accurate placement on layout marks and speeds chip and debris ejection to keep the cut zone cooler.

Key Features

• 3.5 TPI tooth design extends service life in metal cutting applications
• Bi-metal construction bonds high-speed steel teeth to a flexible alloy body for break resistance
• ALL-ACCESS SLOTS simplify plug removal, improve pilot visibility, and accelerate chip ejection
• Thermoset Coating reduces friction and is optimized for cordless tool platforms, delivering up to 25 percent more holes per battery charge
• Lifetime Tooth Break Warranty covers tooth integrity for the life of the saw
• Made in the USA; package quantity of two saws per order

Compatibility

Designed as a general-purpose bi-metal hole saw compatible with standard 3/8 inch and 1/2 inch drill chucks via an arbor, suitable for use with corded or cordless drills and drill presses across residential and commercial applications.

Installation Notes

Installation is performed by electricians, plumbers, HVAC technicians, and general contractors using a compatible arbor and drill. Secure the workpiece before cutting and verify the pilot bit is tight in the arbor before starting. Always wear eye protection and appropriate PPE when cutting metal, as chips and heat are generated at the cut face. Disconnect power or lock out the tool before changing the saw or clearing a stuck plug.
