Diamond Router Heads

Vacuum Brazed Diamond Router Heads are used on an angle grinder to produce a perfect profile on a wide variety of materials including masonry, granite, concrete, marble and stone.
Diamond outperforms standard tungsten carbide heads in durability and speed of cutting.

Vacuum Brazed Diamond tools can run at high speed and dry but try to use a grinder with variable speed (up to 10,000 RPM)
For best results– move the grinder back and forwards in a sawing action until the full depth & shape is achieved .
For polished Granite and Marble surfaces further polishing is required, so use various grit polishing pads.

Use WET or DRY and at any speed, as the diamonds are brazed on using our EXTRA strong bonding vacuum brazed technology. This bonding process allows 40% more exposure of the diamonds to do cutting than electroplated method. They also hold their shape during its life.

There are water holes in the heads if your grinder has water adaption as original manufacturer supply.
Life increases by 50% plus when water is used. But they can be used dry.
Only use water with power tools designed to deliver water to the job.
Always take care if using water near power tools. 

The larger hard rubber rimed bearing holds the top surface for safe and easy control of the profile head during grinding. The small bearing runs on the front face. Both ensures the profile shape is consistent as you move the grinder back and forth until the full depth and shape is completed, ready for the polishing process.

All are M14 thread (as used on most angle grinders in Australia)

Remember to always use personal protection equipment (goggles, hearing protection etc)
Silica warning - see safety instructions here
Do not allow to over heat - air cool regularly.
If cutting wet, only do so on equipment designed for wet cutting. Do not allow water to get into your electrical equipment.

Note - When workers cut, saw  crush, drill, polish 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. 
Use a half face respirator or a PAPR (Powered air purifying respirator).
