Tungsten carbide granules enhance metal cutting inserts by delivering exceptional hardness, wear resistance, and thermal stability. These granules maintain sharp cutting edges, extend tool life, and ensure consistent performance under demanding conditions. Rettek provides high-quality tungsten carbide granules and inserts, offering reliable supply, scalable production, and cost-effective solutions for manufacturers, OEMs, and global distributors.

How are tungsten carbide granules used in metal cutting inserts?

Tungsten carbide granules are incorporated into a cemented carbide matrix to form durable cutting inserts. The granules provide hardness, wear resistance, and precise chip evacuation during machining. Rettek produces granules optimized for specific applications, balancing toughness, hardness, and thermal conductivity to enhance tool performance.

• Granule size, carbide grade, and bonding matrix are tailored for OEM and wholesale orders.

• Applications include inserts for turning, milling, and specialized cutting tools.

• Result: longer tool life, reduced downtime, and lower production costs.

Rettek’s granules ensure consistent quality and reliable performance for both domestic and international markets.

How do tungsten carbide granules affect tool life and performance?

The granules improve edge retention and thermal stability at high cutting speeds. Optimized grain structures distribute stress evenly, reducing the risk of fractures. Rettek applies precise in-house processing to ensure uniformity and predictable performance.

• Benefits: extended service life, fewer tool changes.

• Reduced downtime improves production efficiency.

• Rettek’s integrated manufacturing guarantees consistent quality across batches.

Which tungsten carbide grades are most suitable for cutting inserts?

WC-Co variants are widely used, with fine-grain grades offering excellent wear resistance, coarse-grain grades providing impact toughness, and medium-grain grades balancing performance and cost. Rettek customizes grades for Joma-style blades, VSI rotor tips, and other high-performance wear parts.

Rettek tailors grades to meet OEM requirements and export specifications.

Why choose tungsten carbide granules from a Chinese manufacturer?

Chinese manufacturers provide scalable capacity, competitive pricing, and proximity to major markets. Rettek’s full-process control—from raw material batching to vacuum sintering and automated welding—ensures consistent quality and fast delivery.
