S20Q SDQCL Boring Bar (SDQC for DC-- indexable inserts) — Teknik Makina, left‑hand, Ø25 mm

A S20Q SDQCL boring bar engineered for precision internal turning with DC-- 11T3 indexable inserts, offering a compact 20 mm shank for secure clamping and a 25 mm cutting diameter for medium‑duty bores

• Left‑hand cutting direction for specific turning operations
• Compatible with DC-- 11T3 indexable inserts
• Ø 25 mm cutting diameter with 20 mm shank
• 107.5° cutting angle for stable machining

Precise internal turning with proven mechanical stability

The S20Q SDQCL holder brings measurable benefits to shops that require repeatable bore quality. The combination of a 20 mm shank diameter and 25 mm cutting diameter increases clamping stiffness, which reduces vibration during internal turning and contributes to more consistent bore tolerances. The specified cutting angle of 107.5° optimises the engagement geometry for stable cutting forces, so cycle times remain predictable and tool deflection is minimised. These technical attributes translate into fewer rejected parts and improved throughput on conventional and CNC lathes.

Flexible tooling and quick changeover for efficient production

Designed for the SDQC pocket, this boring bar accepts DC-- 11T3 indexable inserts, enabling rapid insert replacement without disturbing set‑up parameters. The standardised insert interface supports a range of carbide grades and coatings from established manufacturers, allowing the machining strategy to be adapted for different workpiece materials. Keeping insert compatibility as a focal point reduces inventory complexity and supports fast reaction to worn edges, which in turn maintains uptime and lowers process costs per part.

Application guidance and integration into workshop workflows

The left‑hand cutting orientation makes this holder particularly suitable for internal features where tool approach requires reverse cutting direction. The compact overall length of 180 mm and a modest mass of 0.435 kg simplify mounting and reduce unbalanced loads on the turret. When used within a correctly set‑up toolholder and appropriate clamping system, the holder’s geometry supports accurate axial and radial positioning. For process planners and operators, these attributes mean easier set‑up verification and more predictable finishing operations across serial production runs.

FAQ

What inserts fit this boring bar?
The boring bar accepts DC-- 11T3 indexable inserts; this compatibility allows selection of grades and geometries suitable for a range of workpiece materials.

Is the holder right‑ or left‑handed?
This tool is specified for left‑hand cutting direction, intended for turning applications that require reverse approach.

What are the key dimensions for setup?
Important setup values are Ø 25 mm cutting diameter, 20 mm shank diameter and 180 mm overall length; the cutting height is 32 mm.

Can this holder be used on CNC lathes?
Yes, the SDQC holder geometry and compact shank suit turret mounting on both conventional and CNC lathes when clamped correctly.

How does the 107.5° cutting angle benefit machining?
The 107.5° angle improves engagement stability and helps reduce deflection during internal turning, supporting consistent bore quality.
