Diablo Diamond Grit Hole Saw DHS0188DG 3/16 Inch (Integrated Wax Lubricant Snap Lock Plus Mandrel Porcelain Tile Granite Glass Drilling)

Diablo DHS0188DG 3/16-Inch Diamond Grit Hole Saw with Integrated Wax Lubricant

The Diablo DHS0188DG is a 3/16-inch diameter diamond grit hole saw engineered with a continuous rim cutting edge and built-in wax cooling lubricant for dry drilling delicate porcelain tile, glass, granite, and marble. Manufactured in Italy, this 0.05-pound specialized hole cutter connects directly to Diablo Snap-Lock Plus mandrel systems and requires a minimum 1/4-inch drill chuck. Built for tile installers, plumbers, and glass fabricators using handheld rotary drills, its self-cooling core eliminates external water rigs while suppressing edge chipping during plumbing fixture mounting and anchor hole installations.
