tungsten carbide bits for water and geothermal drilling
Carbide drag-bit inserts come in various sizes & grades, the common types are always in stock, we can recommend grade for different applications, we can also manufacture the products according to clients' drawings or samples.
Consider the following necessary information when requesting a quotation or placing
an order for your specific application:
1. Physical dimensions, and related tolerance ( if you have)
2. Grade, or chemical composition (WC: Wt% + Co: Wt% + Others : Wt%) , and properties
(Hardness, Density, coercive force, and WC grain size), and associated tolerances, etc.
3. Operation condition and special requirement.
4. Surface condition: sintered blank, fine grinding.
5. Quantity needed.
Only in this way, we can judge and quote exactly on time.
Advantage:
1. High toughness and wear resistance
2. High weldability.
3. Made with Virgin Raw Materials.
4. All products go through in-process and final inspection.
5. Dimensionally accurate, durable and reliable performance
6. Excellent quality and competitive price
