SGS Tool Co. offers its Z-Carb High Performance Rougher (HPR) line of cutting tools including Imperial and metric sizes, multiple corner radius options, and the company’s Ti-Namite-M coating. These cutters are designed to maximize tool life in hard-to-machine materials.

The line’s five-flute roughing end mills achieve high metal removal rates and a finish of 80 RMS or better on most materials, according to the company. The five-flute design delivers increased productivity compared to three- and four-flute end mills, and the variable indexing geometry is said to contribute to better chatter suppression than symmetrical designs. Providing high wear resistance, reduced friction and preventing cutting edge buildup, the Ti-Namite-M coating is engineered Shoulder Milling Inserts to support metal removal and Carbide Milling Inserts tool life for high-performance operations with difficult materials like titanium.
