Sutton H1160080 8mm (5/16") Diamond Core Bit - M14 Thread, 35mm Cutting Depth
Available
The Sutton H116 diamond core bits are M14 thread diamond segmented holesaws for angle grinders, in 10 sizes from 5 to 51 mm (13/64" to 2"), with a 35 mm cutting depth. They are designed for cutting ceramic and porcelain tiles, marble and granite, bricks, fibre cement and fibreglass.
The diamond segmented tooth design and cut-out slots are designed to reduce the temperature while cutting, which extends the life of the bit and allows it to make more holes before replacement.

Sutton H116 Diamond Core Bit M14 5mm to 51mm - 35mm Cutting Depth, for Angle Grinders: 8 mm
SKU: A0130932 | Model: H1160080
Diameter 8 mm. Sutton H116 Diamond Core Bit - M14
Sutton Tools Diamond core bits fit all M14 angle grinders and are suitable for superior dry cutting of tile, fibre glass, ceramics, porcelain, marble, granite, and brick up to 35mm thick.
The diamond coated tooth design and cut-out slots help to reduce the temperature while cutting and therefore extend the life of the blade which allows it to make more holes before replacement.
Note
It is important to only use the diamond core bit for cutting the materials specified.
If timber or tile underlays are present, do not attempt to cut through these materials using a diamond core bit as this will destroy the core bit.
Use an appropriate hole saw to finish cutting below the tile surface.
