Sumitomo U101710 Mtjn Turning Toolholder Tnmg 432 1x1 Shank

Product Description

The SUMITOMO U101710 is a right-hand MTJN-style indexable turning toolholder designed for negative-rake external turning operations. It accepts TNMG 432 inserts secured by a clamp-and-pin holding method, providing positive insert location and resistance to cutting forces. The shank measures 1 inch wide by 1 inch tall with an overall length of 6 inches and a head length of 1.25 inches. The back-of-bar to cutting edge distance is 1 inch. A -5-degree rake angle and -3-degree lead angle define the cutting geometry. This holder is intended for use by machinists and tooling technicians on CNC lathes and manual turning centers in production and job-shop environments.

The U101710 is suited for external longitudinal turning and facing applications where TNMG 432 inserts are the specified tooling standard. Its right-hand cutting direction makes it compatible with conventional front-tool-post setups on most CNC and manual turning machines. The 1-inch square shank fits standard turret pockets sized for 1-inch toolholders. This toolholder is part of the Sumitomo Multi-Option series, which is oriented toward general-purpose turning across a range of workpiece materials.
