Walter 7031694 Indexable Turning Toolholder Ddjn

Product Description

The WALTER 7031694 is an indexable turning toolholder designed for external turning operations on CNC lathes and manual turning centers. Built in the DDJN-ISO-AUSSEN-INCH-P series, it accepts DDJN-style inserts held in place by a clamp-style insert holding method. The toolholder features a left-hand cutting direction and a negative rake angle of -6 degrees, making it well suited for machining where chip control and tool rigidity are priorities. The shank measures 0.75 inches wide by 0.75 inches tall, with an overall length of 4.5 inches. The steel construction provides the rigidity required for consistent, repeatable cuts in production environments.

This toolholder is intended for external turning applications in both job shop and production machining environments. It is a single-purpose tool configured for left-hand cutting passes. The 93-degree lead angle geometry influences chip flow and cutting forces, making setup planning straightforward for experienced machinists and CNC programmers. The head length of 1.969 inches and a back-of-bar to cutting edge distance of 50.00 mm support proper tool projection planning when setting up a lathe turret or tool post.

Key Features

• DDJN toolholder style with clamp-style insert retention for secure, repeatable insert seating
• Left-hand cutting direction with a -6 degree negative rake angle for stable, controlled cuts
• 93-degree lead angle geometry for predictable chip flow and reduced radial cutting forces
• 0.75 inch square shank (19.05 mm x 19.05 mm) for standard lathe tool post and turret compatibility
• Steel toolholder body provides rigidity and durability in continuous turning applications
• Compliant with ANSI and ISO standards for dimensional consistency

Compatibility

Designed to accept DDJN-P series indexable inserts. Intended for use in standard lathe tool posts and turret stations that accommodate a 0.75 inch square shank. Verify insert size code and cutting direction requirements before installation.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered down and in a locked-out, tagged-out state before any toolholder or insert change. Ensure the shank is fully seated in the tool post or turret pocket and that clamping hardware is tightened to the machine manufacturer's specified torque. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert. Confirm cutting direction and tool offset values in the machine controller before resuming operation.
