Diamond-Grit Cutting Edge
Clean Holes. Less Effort.
Make room for your next tile project with a diamond core bit designed for controlled hole cutting. The steel body, abrasive cutting rim and side slots bring practical features together in one compact tool.
One diameter: 1.57 in / 40 mm. Choose a single bit or a 2-pack with a spare.
A Diamond-Grit Edge for Tile Work
The diamond-grit rim provides the cutting surface, while the steel body supports the hollow core design. Use controlled pressure and a compatible tool setup for your material.
Side Slots Help Clear Cutting Debris
Openings along the body and cutting rim provide clearance for debris during drilling. The design supports dry drilling, but does not eliminate heat buildup. Follow the operating instructions and allow cooling breaks as directed.
Check the Connection Before You Buy
This version has an M10 female threaded connection. Match the spindle thread and pitch of your tool before ordering; it is not a universal fit for every angle grinder.
The bit does not mount directly into a standard drill chuck. Any adapter must be approved for the bit, tool and operating speed.
Choose One Bit or Keep a Spare
- 1 Bit — Single Tool: Includes one 40 mm diamond core bit.
- 2 Bits — Keep a Spare: Includes two identical 40 mm diamond core bits.
Both options have the same cutting diameter. The 2-pack is not a mixed-size set. Angle grinder and adapters are not included.
