KEUE CNC High Hardness MTL 5R0.2 L22 Tungsten Steel Internal Small Hole Counterbore Boring Tool 0.001in Precision for Ferrous
This MTL 5R0.2 L22 left-hand micro boring tool adopts solid tungsten carbide with high-hardness black coating. With 0.2mm nose radius, 5mm shank and 22mm cutting depth, it suits hardened steel, stainless steel and quenched parts for Swiss-type lathe small-bore boring.
The high-hardness black coating greatly enhances wear resistance and surface hardness for hardened material machining. Precision-lapped edges with anti-vibration structure ensure accurate bore dimensions, excellent surface finish and stable chatter-free performance in deep small-bore boring.
Its left-hand design fits reverse boring scenarios in tiny inner bores. The high-rigidity monolithic shank extends tool life, reduces tool-change frequency and downtime, effectively boosting mass production efficiency of precision micro-bored components.
