Diamond Router Bits
Vacuum brazed diamond router bits by Truacut are superior to tungsten carbide bits.
They are used to route shapes into masonry products, granite, marble, natural and synthetic stone, fibreglass, carbon fibre, concrete and compressed fibre cement products.
(May lead to chipping on ceramic and porcelain, so not recommended.)
These bits are for dry use. The bit life is extended when a little water is used, or regular air cooling (run out of the cut for a few seconds).
Only use water with power tools designed to deliver water to the job.
Always take care if using water near power tools eg use an RCD.
All these bits have a 12.7mm (1/2") shaft to suit a 1/2" router!
Routers with a 1/2" collet generally have much more power than the 1/4" routers. This power is needed when shaping hard surfaces.
These bits are also used on CNC machines.
Vacuum brazed diamond bits can run at high speed and dry (up to 10,000 RPM).
For best results, try to use a router with variable speed. Start at half speed.
Run backwards and forwards until desired depth and shape is achieved.
These bits will eventually wear out.
How long they last depends on many factors such as:
- Power of the tool you are using it on
- What material you are routing
- Skill of the operator
- How deep you are routing
- How much force they apply (don't force it)
- Regular air cooling will keep the bit cooler and lasting longer than a long constant cut
These bits are relatively inexpensive, so it maybe better to get an extra bit rather than wear it out mid job.
Remember to always use personal protection equipment (goggles, hearing protection etc).
Use an RCD if using water near your power tools.
Silica warning - see safety instructions here.
Do not allow to over heat - air cool regularly.

Note - When workers drill, saw, polish, cut, crush or grind products that contain silica, particles are created, which are one-hundredth of the size of a grain of sand. These can get stuck deep in the lungs. Ensure precautions to limit exposure to dust are in place. See our dust collection accessories here
Use a half face respirator or a PAPR (Powered air purifying respirator).
See the WA government's info on silica dust here.
