Milwaukee 49-56-0505 Diamond Max Hole Saw Bit 1/4 Inch

Product Description

The Milwaukee Electric Tool Corp 49-56-0505 is a Diamond Max hole saw bit designed for cutting clean, precise holes in hard, brittle surfaces including glass, tile, and ceramic. Built with a diamond-coated cutting edge and a 1/4 inch cutting diameter, this bit delivers the abrasive cutting action required to work through materials that standard steel hole saws cannot handle. It is a compact, single-purpose tool used by tile setters, plumbers, and general contractors when penetrations through finished surfaces are needed without cracking or chipping the surrounding material.

This bit is suited for residential and light commercial applications where small-diameter holes are required through glazed ceramic tile, porcelain, glass, and similar hard surfaces. Common use cases include fixture installation, escutcheon plate fitting, and drain outlet penetrations through finished tile work. The 1/4 inch diameter makes it appropriate for small fastener clearance holes and similar precision penetrations.

Key Features

• Diamond-coated cutting edge for use on glass, tile, and ceramic
• 1/4 inch cutting diameter for small, precise penetrations
• Compact design suited for tight or finished-surface work
• Sold as a package of 3 units per order

Compatibility

Designed as an OEM-style replacement and consumable hole saw bit for use in standard rotary drills and drill drivers accepting compatible shank sizes for hard-surface drilling applications.

Installation Notes

Installation and use of this bit should be performed by qualified trade professionals familiar with hard-surface drilling techniques. Always power down and unplug the drill before changing bits. Use water or a compatible cutting fluid to cool the bit during operation and extend cutting life. Avoid applying excessive lateral pressure, which can cause bit deflection or surface cracking.
