Small Hole Thread Cutter VNTR 030-11 Tungsten Steel Internal Thread Lathe MIR Alloy Small Diameter HSS Square Shape CNC Aluminum
This VNTR series small-bore internal threading insert features solid tungsten carbide construction with KT20 wear-resistant coating. Its modular replaceable design removes the need for full shank replacement, with full specs for CNC and Swiss-type lathe micro threading.
Precision-ground thread cutting edges with optimized anti-vibration geometry ensure stable chatter-free threading in narrow inner bores. The KT20 coating guarantees accurate thread profiles, superior surface finish and smooth chip evacuation for steel and stainless steel.
The insert-replaceable structure eliminates repeated tool presetting, greatly reducing setup and tool-change downtime. It significantly cuts overall tooling costs and effectively improves mass production efficiency of precision miniature threaded parts.
