Industrial sectors such as machinery, automobiles, ships, chemical industry, craft carving, etc.


Burr Application:

- Deburring
- Contouring
- Edge chamfering/rounding
- Milling out in prepareation for build-up-welding
- Prepareation of weld seams/weld dressing
- Cleanning cast material
- Modification of workpiece geometry
- Extremly high stock removal performance on all austenitic ,rust-and acid-resistant steel, stainless steel
- Substantially reduced vibration and less noise


Burr Shapes:

- Cone Radius End




1. It can be used to finish Various metal mold cavities;

2. Clean up burrs, burrs and welds of castings, forgings and weldments;

3. Finishing the inner hole surface of mechanical parts;

4. It can be used into various metal and non-metal craft carving etc.
