The roller- cone bits are used to drill all kinds of formations, from soft to hard. The softer formations use steel-tooth bits, and the harder use tungsten carbide.

The biggest advantage the tricone bits have over any other drill bit is the test of time. They have been proven time and time again, and they're the best at controlling the trickier situations. Tricones' ability to handle both soft and hard formations gives them the flexibility that other drill bits do not have.

SUZHOU SAIL is a high-tech corporation that is specialize research, development and production of resinoid, vitrified and eletroplated diamond & CBN Wheels , resinoid and metal bonded ultra thin and precision diamond/CBN blades.

Diamond Grinding Wheels Available Material:
1. Diamond
2. Metal-bond diamond (hold the grits strongly, good wear resistance&shape maintenance)
3. Resin-bond diamond (the elastic resin bond makes the surface improved, super sharp)
4. CBN (mainly used for high-hardness materials grooving and cutting, like tool steel, mould steel, heat-resistant steel, stainless steel, casting iron etc.)

Can be used for grinding and polishing :
1. Semiconductor Materials 
2. Oxide ceramic materials
3. Magnetic materials
4. Crystal, glass, quartz, carbide...etc.

Our Grinding Gear Grinding Tool's Grind Ability is very better.
