Who We Are
Zhuzhou Pute Carbide Tools Co., Ltd. is a professional manufacturer of carbide inserts, cutting tools, and tooling systems. Located in Zhuzhou, China — the capital of cemented carbide — we produce high-quality turning inserts, milling inserts, drilling inserts, and special tooling for CNC machining worldwide.
Our production covers in-house powder preparation, pressing, sintering, grinding and coating — every insert we ship is made in our own plant, not sourced from third parties.
From Powder to Precision — Inside the PUTE Factory
Every PUTE insert is produced in-house — from raw tungsten carbide powder to a finished, inspected cutting tool.
Raw Material Mixing
Tungsten carbide powder is weighed and blended to exact grade formulations.
Powder Granulation
Spray drying turns the mixture into free-flowing, uniform granules.
Powder Pressing — BERNEX
High-precision BERNEX presses form green compacts with tight tolerance.
Powder Pressing — Osterwalder
Osterwalder SP160 presses cover complex geometries and larger inserts.
Vacuum Sintering
Vacuum sintering at ~1,400 °C delivers full density and hardness.
Precision Machining
GF grinding machines finish edges, radii and tolerances to micron level.
Quality Inspection
Every batch is checked for geometry, hardness and surface integrity.
Automated Warehouse
Finished goods are stored and picked in an automated racking system.
