YG8 Tungsten Carbide Cemented Tips Cone Burr Set
YG8-grade cemented-tip cone burrs – the tough grade for impact-prone fettling and foundry work.
Design and Construction
Cone heads with cemented YG8 tips braised onto steel shanks: YG8 is the coarse-grain, high-toughness grade that survives interrupted cuts and casting knock where finer grades chip.
How It Works
The coarse YG8 grain absorbs impact while the cone profile concentrates cut at the point – fettling feed pads and parting lines without edge collapse.
Applications
Foundry fettling, forging flash removal, heavy repair, impact-prone cleanup.
Field Cases
- Iron foundry: YG8 tips survived gate knocking where a finer grade chipped on day one.
- Forge shop: flash removed on hot-worked blanks – interrupted cut after interrupted cut.
- Heavy repair: tapered pads dressed on 20 mm plate fixtures.
