DDJNR for DN-- Indexable Inserts — left‑hand turning toolholder by Teknik Makina, 125 mm overall length, 20 mm height

The DDJNR for DN-- Indexable Inserts is a left‑hand turning toolholder engineered for conventional lathe operations, offering stable clamping for DN-- 1104 inserts in medium‑duty external turning and facing applications

• Left‑hand turning orientation
• Fits DN-- 1104 indexable inserts
• 125 mm overall length for compact set‑ups
• ISO designation DDJNL 2020 compatible

Precise left‑hand turning with controlled chip formation

The toolholder is configured for left‑hand cutting, which places the cutting forces and chip flow in a predictable direction and helps protect the machine spindle and fixtures. With a defined cutting angle 93° and support for indexable inserts, the geometry reduces radial loads while maintaining precision across repeated cuts. This results in consistent surface finish and reduced rework, making the component process more economical in medium‑batch production.

Compact, rigid dimensions for steady machining

A compact design with 125 mm overall length and a body height 20 mm provides a short overhang that enhances rigidity and reduces chatter. The holder’s cutting head width 25 mm and cutting height 30 mm are balanced to give reliable support to the insert while keeping mass low at 0.421 kg, which simplifies handling and tool changes. The reduced vibration improves tool life and allows slightly more aggressive feeds without sacrificing workpiece accuracy.

Fast insert changes and workshop compatibility

This clamping solution accepts DN-- 1104 inserts and follows the ISO DDJNL 2020 designation, so replacement inserts and compatible indexable grades are widely available. The shank reference K11 indicates the compatible boring‑bar or toolpost interface for secure mounting. Quick access to the clamping screw and a straightforward seating geometry shorten downtime during tool exchange, improving machine availability and overall process throughput. If further clarification on mounting or insert grades is required, technical advisers are available for tailored recommendations.
