Trapezoidal T-Threaded Insert GER2.0TR 3.0 4.0-B 5.0 6.0-D KM15H
This GER series 30° metric trapezoidal T-threading insert covers 2.0TR, 3.0TR-B, 4.0TR, 5.0TR and 6.0TR-D pitch specifications, paired with premium KM15H coated carbide grade. It is specially designed for small-bore internal trapezoidal thread machining on carbon steel and alloy steel via CNC lathes.
The KM15H grade combines high-toughness carbide substrate with wear-resistant CVD coating, delivering outstanding edge stability and durability under continuous threading loads. Precision-ground 30° TR profile ensures strict dimensional accuracy and smooth flank finish, with optimized chip geometry ensuring reliable chip evacuation.
Fully compatible with standard GER series threading tool holders, these inserts enable quick indexing to minimize machine downtime. They are widely applied in lifting machinery, power transmission, automotive and hydraulic industries, providing a cost-effective solution for mass trapezoidal thread production.
