Tungaloy Expands Y-Pro Series with 25° Corner Angle Inserts for High-Precision Profiling and Undercutting!
Tungaloy Corporation has expanded its Y-Pro Series with the introduction of precision-ground YCGT inserts featuring a 25° corner angle, addressing the growing demand for accuracy, stability, and surface quality in small-part machining. The new inserts are specifically developed to support complex turning operations such as profiling, taper machining, undercutting, and V-groove machining, where tight tolerances and repeatable performance are critical.
In industries focused on high-precision components—such as medical devices, automatic lathe production, and shaft manufacturing—machining accuracy and surface consistency are becoming increasingly important. Applications like medical implants, miniature fittings, and precision shafts require flawless geometry and smooth finishes to meet stringent functional and regulatory requirements. According to Tungaloy, demand for inserts with a 25° corner angle has been rising in these segments, as this geometry allows access to intricate features while maintaining excellent dimensional control.
Despite this demand, manufacturers have faced challenges due to the limited availability of ground inserts optimized for such applications. Conventional solutions often struggle to deliver stable machining and consistent quality, especially during fine profiling or taper cutting on small components. The newly added YCGT inserts are designed to overcome these limitations, providing a reliable and purpose-built solution for today’s precision machining needs.
The Y-Pro Series is engineered as a versatile tool line for advanced turning operations. Its distinctive 25° corner angle enables high-precision machining while minimizing the risk of tool interference with the workpiece. This makes the inserts particularly suitable for intricate geometries and confined cutting areas. In addition, the Y-Pro Series is compatible with multi-tasking machines and automatic lathes, supporting efficient integration into modern, high-productivity manufacturing environments.
One of the key strengths of the new YCGT inserts lies in their precision-ground construction. Tungaloy states that these inserts deliver dimensional accuracy and cutting edge quality comparable to grinding processes. This high level of precision ensures stable machining with minimal dimensional variation, even during demanding finishing operations. The 25° corner angle further enhances the ability to machine complex shapes and fine features with confidence, supporting manufacturers aiming for consistent, high-quality results.
Chip control is another critical aspect addressed by the Y-Pro Series. The inserts are equipped with Tungaloy’s JS breaker, which features a unique three-dimensional geometry designed to optimize chip breaking and evacuation. This design performs effectively across a wide range of cutting conditions, from light finishing to deeper cuts. Improved chip control reduces the risk of chip entanglement and interference with the workpiece, enhancing both productivity and operator safety while maintaining process stability.
The inserts are also offered in Tungaloy’s SH7025 grade, which is engineered to provide an optimal balance between wear resistance and toughness. This grade supports stable tool life during extended continuous machining and helps maintain consistent performance over long production runs. Additionally, SH7025 contributes to excellent surface finish quality, producing smooth, glossy surfaces that often reduce or eliminate the need for secondary finishing operations.
With the expansion of the Y-Pro Series to include 25° corner angle YCGT inserts, Tungaloy offers manufacturers a refined solution for precision turning applications. The combination of precise geometry, effective chip control, and durable grade technology positions the Y-Pro Series as a strong choice for achieving high accuracy, superior surface quality, and reliable performance in small-part and complex machining environments.
