Product Description

Product Description

Threading inserts

Our tungsten carbide threading inserts are high-precision indexable cutting tools specially designed for CNC lathe thread turning, widely used in mechanical manufacturing, automobile parts, pipeline fittings and hardware processing industries. Manufactured with premium ultra-fine grain tungsten carbide substrate, these threading tools combine high surface hardness, excellent structural toughness and outstanding wear resistance, effectively solving common machining problems such as tool chipping, thread burrs and rapid tool wear during continuous and intermittent threading processes.
We supply a complete series of standard threading insert models, covering mainstream specifications including 11ER, 11IR, 16ER, 16IR, 22ER and 22IR. ER inserts are applied for external threading, while IR inserts are dedicated to internal threading, meeting diverse internal and external thread machining demands. All inserts comply with international ISO standards with precise dimensional tolerance, ensuring perfect compatibility with standard threading tool holders and stable repeatability during mass production.
These carbide threading inserts support full-range international thread standards, including Metric, UNC, UNF, NPT, BSPT and Whitworth threads, with optional pitches ranging from 0.5mm to 6.0mm. Equipped with professional CVD and PVD coating technologies, different graded inserts adapt to various workpiece materials. Thick-layer CVD coated inserts are suitable for high-efficiency mass processing of carbon steel and alloy steel. Advanced PVD coated grades feature low friction and anti-adhesion performance, perfectly solving built-up edge issues in stainless steel and heat-resistant steel threading, delivering smooth and high-precision thread surface quality.
Optimized tooth profile design and exclusive chip breaker structure enable smooth and stable chip removal, reducing cutting vibration and thread deformation. Strict precision grinding technology guarantees accurate tooth shape and pitch, greatly improving thread machining accuracy and qualification rate. Compared with traditional solid threading tools, our indexable threading inserts significantly lower production costs and improve machining efficiency.
