In recent years, achieving both higher productivity and energy efficiency has become a critical challenge in external turning operations. This is especially true in mass production settings for general machinery and automotive components, where reducing machining time is essential. The demand for high-efficiency cutting tools is growing rapidly, as shorter machining times not only improve operational efficiency but also help reduce machine operating hours, thereby lowering electricity consumption. This aspect is gaining attention from an environmental perspective as well. Against this backdrop, the market is increasingly seeking the introduction of higher-performance tools.




Product Overview
AddMultiTurn is a highly efficient tool capable of handling various turning operations—including external turning, facing, profiling, and high-feed turning—with a single tool. Its double-sided insert with six cutting edges enhances tool life and productivity, while also contributing to cost reduction through fewer tool changes.




Feature 1: Expanded Holder Variations to Accommodate Diverse Machine Specifications

• PSC types are available in three sizes: C4, C5, and C6.
• Square shank types will be released in 2025, offered in 20 mm and 25 mm, making them compatible with a wide range of machine tools.
• This broad compatibility allows more manufacturing sites to benefit from the high performance of AddMultiTurn.

Feature 2: Enhanced Machining Performance with Multi-Point Coolant Supply Near the Cutting Edge

• Coolant is supplied from a total of seven points: four from the top and three from the bottom.
• The design ensures direct coolant delivery to cutting edges for both forward and reverse turning, significantly improving cooling and chip evacuation.
• Suppresses cutting heat, reducing insert wear and greatly extending tool life.

Feature 3: High-Rigidity Internal Coolant Holder Supporting Multi-Directional Machining

• The newly expanded internal coolant holder lineup features a high-rigidity clamp with an optimized coolant path.
• Ensures high stability in multi-directional machining—such as forward turning, reverse turning, facing, and profiling—which is a hallmark of AddMultiTurn.
• Particularly in high-feed reverse turning, the synergy of tool rigidity and coolant delivery performance enables high-efficiency machining.
