Parting tool holder D879TM — left-hand parting holder, 5 mm cut, Teknik Makina

The Parting tool holder D879TM is engineered for left-hand cut-off operations and integrates into standard boring-bar systems for clean, repeatable parting with indexable inserts

• Left-hand cutting orientation
• 5 mm maximum cutting width
• 25 mm clamping height and width
• Compatible with Sandvik indexable inserts

Stable clamping for cleaner cuts and less vibration

The holder’s rigid 25 mm clamping dimensions and compact 150 mm overall length combine to reduce deflection during parting, producing more consistent component faces and longer insert life. The relatively low weight of 0.725 kg supports rapid spindle acceleration without compromising stability. By pairing a narrow 5 mm cutting width with a robust clamping geometry, the system minimises chatter and supports reliable repeatability in series production or workshop batches.

Seamless integration with existing tool systems

Designed to accept standard indexable parts, the tool holder carries an ISO 2525 designation and is specified as compatible with Sandvik inserts and the 5C-123 SDV-L boring-bar format. This compatibility reduces setup time and inventory complexity: existing inserts and holders can be adopted quickly, so changeovers are faster and machine uptime improves. The left-hand orientation matches lathe programmes and fixture arrangements where cuts progress from the component’s right side towards the chuck.

Productivity through controlled plunge depth and geometry

With a maximum plunge depth of 18 mm, the holder is suitable for many common parting operations without unnecessary step changes in tooling. The controlled geometry supports efficient chip control when used with appropriate inserts and cutting parameters, helping to reduce secondary operations. The holder’s measured proportions enable confident feed and speed selection — prioritising throughput while maintaining surface quality and extending insert life.

Practical service and supply reliability from Metav

Metav’s workshop focus ensures the holder is supported by practical advice and dependable European distribution. The combination of a proven tool geometry and Metav’s logistics reduces procurement friction for precision shops and production facilities alike. For complex applications, Metav’s consultants can advise on insert selection and mounting to match material, machine power and cycle targets, helping to achieve measurable productivity gains.
