25mm Drill Bar S20Q SD-CR Right-Hand, 62.5° Cutting Angle, 35mm Insert Height - Teknik Makina

Take advantage of the combination of a compact Ø25 mm body, secure 20 mm shank clamping and fast insert changes with DC-- 11T3 indexable tips for stable, repeatable internal machining; order via Metav Werkzeuge or request technical guidance from the Metav specialists if specification matching is required.

S20Q SD-CR Boring Bar — Ø25 mm · Right-hand · Teknik Makina

The S20Q SD-CR boring bar is a right-hand internal turning tool designed for use with DC-- 11T3 indexable inserts, offering reach and rigidity for precision internal machining tasks.

• Ø25 mm body diameter
• Compatible with DC-- 11T3 inserts
• 180 mm overall length
• Right-hand cutting direction

Consistent bore quality through stable geometry

The tool’s Ø25 mm body diameter combined with a 20 mm shank ensures a balance of reach and rigidity that reduces chatter and stabilises tool engagement. This geometry, specified by the ISO designation S20Q SD-CR, supports consistent bore profiles and surface finish. The indexable insert system with DC-- 11T3 inserts permits rapid insert replacement; this reduces downtime compared with brazed or solid tooling and keeps production run-times predictable. The stated 62.5° cutting angle contributes to controlled chip flow and predictable cutting forces.

Improved process reliability and reach for internal turning

With an overall length of 180 mm and a designed cutting height of 35 mm, the bar provides sufficient reach for moderate-depth internal operations while maintaining clamping stability via its 20 mm shank. Right-hand cutting orientation offers standard compatibility with common lathe setups and CNC boring heads. The modest mass (approx. 0.443 kg) keeps inertial forces low, aiding rapid acceleration and deceleration in automated cycles; this supports higher throughput without sacrificing positional control. The ISO-style shank ensures straightforward integration into existing toolholders.

Easy integration into indexable-insert workflows

Designed specifically for indexable inserts, the bar accepts the DC-- 11T3 family, simplifying stock management and spare-part logistics. The SD-CR geometry focuses on reproducible clamping and repeatable cutting-edge position, which is beneficial when switching between batches or when quick reconditioning is required. For procurement and maintenance planning, the compact design reduces storage footprint and the insert-based concept lowers per-cutting-edge replacement cost compared with solid tools, while preserving the quality demanded in precision internal machining.

FAQ

What insert type fits this boring bar?
The S20Q SD-CR boring bar is designed for DC-- 11T3 indexable inserts and is compatible with standard holders for that insert family.

What are the key dimensions to check for toolholder compatibility?
Check the 25 mm body diameter, 20 mm shank diameter and 180 mm overall length when matching the S20Q SD-CR (Teknik Makina, SKU K174TM) to a toolholder or boring head.

Is the cutting direction specified for this bar?
Yes, the bar has a right-hand cutting direction suitable for conventional right-hand internal turning operations.

How does the SD-CR geometry affect machining performance?
The SD-CR geometry provides reproducible clamping and a defined cutting edge position, which helps to maintain consistent bore quality and simplifies insert indexing during series production.

What is the declared cutting angle and why is it relevant?
The declared cutting angle is 62.5°; this influences chip formation and cutting forces, contributing to controlled chip evacuation and surface finish.
