Diablo DHS0312DG Diamond Grit Hole Saw, 5/16 in Dia

Diablo's high-performance diamond grit hole saws deliver longer life and faster material removal when boring holes into tile, stone and glass. A continuous rim diamond grit edge delivers lasting durability and maximizes cut quality in masonry applications. An integrated wax lubricant cools the cutting edge and reduces friction and heat build-up while drilling holes. Diablo's hole saws are compatible with Diablo's SnapLock PLUS mandrel system, resulting in quick, easy and effortless cup changes.
