125mm SDHCL 2020 Turning Holder for DCMT 11T3, 107.5° left - Teknik Makina

Turning Holder — SDHC for DCMT Indexable Inserts by Teknik Makina

The Turning Holder is a robust SDHC clamping tool designed for left-hand turning with DCMT 11T3 indexable inserts, suitable for precision external turning in workshop and production environments.

• Compatible with DCMT 11T3 indexable inserts
• Overall length 125 mm for stable overhang
• ISO designation SDHCL 2020 for clear tool selection
• Left-hand cutting orientation for specific lathe setups
• Cutting head width 25 mm for rigid clamping

Consistent clamping for repeatable turning results

The clamping geometry of this holder is configured to secure DCMT 11T3 inserts with minimal runout, delivering consistent cutting conditions across batches. Thanks to the SDHCL 2020 designation, the tool can be matched quickly to setup sheets and CAM data. The 125 mm overall length balances accessibility and stiffness, reducing vibration and improving surface finish for external turning operations.

Rigidity and design reduce tool deflection

A compact cross-section with a 20 mm Width and 20 mm Height increases the holder's rigidity during cuts, ensuring stable chip formation and extended insert life. The 25 mm cutting-head width concentrates clamping force where it matters, which translates to improved dimensional accuracy. Left-hand cutting orientation is explicitly defined to avoid setup errors and to match specific lathe configurations.

Optimised for professional workshops and serial production

This SDHC Turning Holder is aimed at machinists and production engineers who require reliable toolholding for repeatable parts. The design supports frequent insert changes and precise indexation, making it suitable for medium to high-volume turning tasks. For shops that standardise on triangular indexable inserts, the holder simplifies tooling logistics and maintenance.

Quick orientation and practical notes for mounting

Install the insert so that the rake face and seating match the holder pocket geometry; the SDHC clamping system secures the DCMT 11T3 insert reliably while allowing correct indexation. The specified left-hand cutting direction must be observed when planning toolpaths or programming lathe cycles. For unfamiliar users: DCMT 11T3 denotes a triangular indexable insert (DCMT shape) with a 11T3 size, commonly used for external turning on a wide range of materials.
