Diamond Router Bits

Vacuum Brazed Diamond Router bits by Dymaxion are superior to tungsten carbide bits.
They are used to route shapes into masonry products, granite, marble, natural and synthetic stone, ceramics, carbon fibre, concrete and compressed fibre cement products.

These bits are for wet or dry use. The life of the bit is extended when water is used.
Only use water with power tools designed to deliver water to the job.
Always take care if using water near power tools. 

All are 12.7mm (1/2") shaft

Vacuum Brazed Diamond tools 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.

Remember to always use personal protection equipment (goggles, hearing protection etc), and use an RCD if using water near your power tools.
If cutting dry, be aware of silica dust. See more here.
