Product Description

The SANDVIK COROMANT 5756998 is an indexable cutoff blade tool block designed for parting and grooving operations on CNC lathes and turning centers. Part of the T-Max Q-Cut series, it accepts neutral-cutting indexable inserts and provides a rigid, repeatable mounting platform for blade-style cutoff tooling. The block measures 3.1496 inches in overall length and 1.7902 inches in overall height, with a 0.75-inch shank height and a 1.25-inch shank width. This tool block is installed by machinists and CNC turning specialists in production and job-shop environments requiring consistent part-off performance.
