The indexable single-edged TB-REAM is a high-speed reaming system with internal coolant holes and two cutting edges with four lead angles and three rake angle options. The standard TB-REAM line covers reaming applications from 8-32mm diameters. The blades with high wear resistant carbide or cermet pads provides a combination of economical and high precision results on a range of materials. The TB-REAM has been designed to achieve tight hole tolerances of H6 with a high surface finish quality. This exceptional level of accuracy eliminates additional operations such as honing or grinding processes reducing production times considerably. When large batch numbers are involved, the indexable insert with the double cutting corner provides high productivity and a very economical solution.
