Our Bad Dog Diamond Hole Saws use the same 46-grit diamond as our HDII Diamond Grinding Wheels and are backed by the same lifetime guarantee.
They’re made for drilling the hard stuff that regular hole saws struggle with. Porcelain tile, stone, concrete, and masonry cut cleanly, and they also work well on granite countertops, composites, carbon fiber, drywall, and older horsehair plaster.
Each hole saw threads straight onto an angle grinder with a 5/8-11 arbor. Running them on a grinder gives you more speed and torque than a hand drill, which makes cutting dense materials faster and easier to control.
When starting a hole, begin at about a 30-degree angle and rock the saw into the surface until it’s fully cutting. Taking a minute to mark the hole first helps keep everything lined up, especially on tile or stone.
Common uses include plumbing holes in tile and stone, running conduit through block walls, general construction work, and drilling stone for anchors or pins.
