New widths for Kennametal A4 groove and turn insert range

Kennametal’s A4 groove and turn inserts are now available in narrow groove widths of 1.5, 2.0, and 2.5 mm, bringing the complete range of A4 sizes from 1.5 to 10 mm. “The narrower widths along with the proven carbide grades and chipbreaker geometries can save customers material and money,” says Latanyua Robinson, Kennametal product manager, grooving, North America. “Separate tools for turning, grooving, and cutoff can be eliminated.” Kennametal’s A4 inserts feature a unique double-ended design available in full radius and rectangular types as well as precision-ground and moulded utility styles. The A4 insert features a distinct guide rail on the top and a 120° v-prism on the bottom that seat it more securely in the toolholder. This provides improved rigidity for the entire system resulting in improved performance, particularly in side turning, says the company.
