Milwaukee Tool 49-56-0518 Diamond Hole Saw 1-1/8 Inch

Product Description

The MILWAUKEE TOOL 49-56-0518 is a diamond-tipped hole saw designed for cutting through hard surface materials including porcelain, tile, and natural stone. It carries a 1-1/8 inch cutting diameter and a 1-1/2 inch cutting depth, making it suitable for through-cuts in standard tile and stone installations. The continuous diamond cutting edge distributes load evenly around the rim, reducing chipping and cracking at the cut perimeter. This hole saw is arbored and compatible with power drills, allowing licensed plumbers, tile setters, and mechanical contractors to cut clean, precise holes for pipe penetrations, fixture outlets, and drain installations in hard surface substrates.

This hole saw is used in residential and light commercial applications wherever tile or stone must be penetrated. Common install scenarios include bathroom and kitchen tile work requiring openings for supply lines, drain flanges, and escutcheon cutouts. It is also applicable in pool and spa deck tile work where plumbing penetrations through ceramic, porcelain, or natural stone are required. The arbored design allows direct chuck mounting to a standard power drill without a separate arbor adapter in most configurations.

Compatibility

Designed for use with power drills. Suitable for cutting porcelain, tile, and stone materials. Consult the tool manufacturer for chuck size and arbor fitment confirmation before use.

Installation Notes

Installation should be performed by a qualified tile setter, plumber, or mechanical contractor familiar with hard surface cutting procedures. Use water cooling at the cut point to extend diamond life and reduce heat buildup in the substrate. Secure the workpiece firmly before drilling and start at a low angle to establish a pilot groove before drilling straight through. Always wear appropriate eye and hand protection when cutting tile or stone.
