Carboloy MTGNL-12-3 Carbide Lathe Turning Tool Holder

Carboloy MTGNL-12-3 Carbide Lathe Turning Tool Holder with a 3/4" square shank and a 4-1/2" overall length is designed for external turning on a lathe. It accepts TNMG inserts (TNMG 33 geometry), providing an insert-ready platform for carbide tooling. The MTGNL-12-3 designation identifies the tool holder style and insert compatibility, ensuring proper seating and alignment of carbide inserts during turning operations. The 3/4" square shank delivers rigidity for typical turning setups, while the 4.5" reach supports common small-to-mid-size machine configurations. This holder is intended for use with standard TNMG carbide inserts to perform roughing and finishing passes on workpieces, with performance dependent on insert grade and coating. The compact form factor and standard insert interface help maintain consistent cutting geometry and predictable results across routine turning tasks. For shops sourcing insert-ready tooling, MTGNL-12-3 offers a straightforward solution that pairs Carboloy’s holder design with TNMG insert versatility.
