Diablo DHS0250DG Diamond Grit Hole Saw 1/4 Inch

Product Description

The DIABLO DHS0250DG is a 1/4-inch diameter diamond grit hole saw engineered for cutting tile, stone, and glass without a pilot bit. A continuous rim diamond grit edge delivers fast material removal and lasting cut quality in hard masonry materials. An integrated wax lubricant cools the cutting edge during operation, reducing friction and heat buildup. The 1/4-inch hex shank allows direct use with standard hand-held drills. Licensed trade installers and finish tradespeople working with porcelain, ceramic, granite, marble, slate, or glass will find this saw suited to precision hole work in demanding field conditions.

This hole saw is designed for hand-held drill use in residential and commercial tile and stone applications. Typical install scenarios include setting fixture penetrations in tiled walls and floors, countertop cutouts in natural stone, and glass panel work. Starting the cut at a 45-degree angle or using a positioning jig eliminates the need for a pilot bit, reducing setup time on the job. Compatible with the DIABLO Snap-Lock Plus mandrel system for fast cup changes between cuts.

Installation Notes

Installation is performed by tile setters, stone fabricators, or general tradespeople using a standard hand-held drill. Before starting, secure the workpiece firmly to prevent movement during the cut. Begin drilling at a 45-degree angle to establish a seat, or use a hole-saw positioning jig to prevent walking on smooth surfaces. Keep steady, moderate pressure on the drill and allow the wax lubricant to work - do not force the saw through the material, as excess pressure can crack brittle substrates or shorten diamond grit life.
