Cutting edge of tungsten carbide particles bonded to alloy steel back cuts extremely hard abrasive materials. High heat and abrasion resistance; no teeth to dull or chip; resists snagging; smooth cutting; greater wear resistance. Used in applications such as laminates, fiberglass, ceramic tile, marble and slate, cast iron or composites; 1/4" Quick Change shank.

For use with ARTU hole saws 02805, 02810, 02820, 02830 02840, 02850, 02860, 02870 and 02890 (sku nos 322.1645, 322.1652, 322.1660, 322.1686, 322.1694, 322.1702, 322.1710 and 322.1744).

No arbor required. Split point pilot bit for faster penetration and less walking. Oversized slot in hole saw for easy plug removal with low torque, little pressure required for fast, easy cutting. Continuous, brazed edge lasts longer in tile and stone.

Welded diamond tip for durability. Provides a quick, clean way to precisely drill through the densest, most abrasive tiles, including glazed ceramic and rock hard porcelain (both solid body and glazed). Reverse spiral threads permit continuous water cooling, so you can run the bits at higher speeds without fear of overheating. Core-ejection slot removes a plug of waste material, which is ideal for repetitive hole boring jobs.

Tungsten carbide abrasive hole saw. Self-sharpening particles, so when a particle chips, a new surface is created in its place. Comes with arbor and pilot. For use with any variable speed hand drill. Cuts ceramic tile, concrete block, cement board, brick, fiberglass, plexiglas, PVC, wood with nails, cultured marble and drywall.
