We can make any sizes as your requirement
Material	100% Cemented carbide substrate and Diamond layer
Application	PDC (polycrystalline Diamond Compact) drill bit is a new product after the hot-pressed and electroplated drill bit in recent years. With special high-frequency welding techniques, PDC of high wear resistant is welded to the body as cutting edges. PDC bit is mainly used for geological prospecting coal exploration, water conservancy and power engineering, etc.And mechanical industry,oil well drilling,coal mining or quarrying.
Characters	PCD bits uses PCD as main cutting components, with the excellent wear-resisting and impact toughness of the PCD.It has a long useful life, high-efficiency, and good cost performance.
Productive technology	Surface  treatment			Sinter
	“Mirror” polishing			High temperature high pressure sintering
Abrasive ratio	>185
	OEM /ODM			Sample
	Yes			available

FAQ

Q:What is cemented carbide ?

A: Cemented carbide is a hard material used in machining tough materials such as carbon steel or stainless.

Carbide tools can also withstand higher temperatures .

 

Q: Which grades are useful in metal forming applications?

A:  Grades employed for metal forming applications are typically based on coarse grain sizes (3 to 8 mm) and

high binder contents (15 to 30 wt. %).

 

Q: Which grades are useful in earth drilling or boring applications?

A: The best compromise is usually arrived at by using grades that are based on coarse grain sizes (3 to 8 mm) 

and relatively low Co levels (6 to 16 wt. %).
