Walter 6687226 Indexable Cutoff Blade Tool Block

Product Description

The WALTER 6687226 is an indexable cutoff blade tool block designed for parting and grooving operations on CNC lathes and turning centers. Built to Series G2661-P-INCH specifications, it accepts a range of WALTER indexable cutoff blades and provides a rigid, repeatable clamping platform. The block measures 3.74 inches overall length with a 1.0 inch square shank height and 1.0 inch shank width, and weighs 1.825 pounds. It is installed by machinists and toolroom technicians working in production turning environments where consistent blade positioning and fast insert changeovers are required.

This tool block is suited for cut-off applications in both job shop and production turning environments. The 1.0 inch square shank fits standard machine tool holders and gang-style turrets commonly found on mid-size CNC lathes. The G2661-P-INCH series is sized for inch-dimension setups, making it a practical choice for shops running imperial tooling standards. Compatible blades span multiple WALTER G-series families, giving toolroom personnel flexibility when selecting blade geometry or width for a specific parting operation.
