Dapra’s high-performance Rhino-Carb Toroid insert line includes an octagonal geometry designed for general face milling. The insert features a 45-degree lead angle that increases feed capacity for face milling, profiling, helical interpolation and chamfering applications. Each of the insert’s eight edges is designed with an integral wiper flat for quality surface finishes.
The Rhino-Carb OPMH eight-sided inserts are offered in 1/2", 5/8" and 3/4" IC, with either a T-land or dished-face edge. T-land inserts feature a reinforced cutting edge for steels, irons and hard milling, while the dished-face option provides a high-positive cutting edge for stainless steels, high-temperature alloys and gummy materials.
Designed for aggressive metalcutting and long tool life, the insert line offers enhanced strength and heat absorption capabilities when compared to ground inserts, the company says. A positive top rake reduces cutting forces and torque, while a stronger cutting edge accommodates heavier chip loads and increases shock absorption. The inserts are also available in round/button, high-feed and square geometries with a variety of grades and coatings.
