Boring bar S20Q SDQCR — SDQC for DC-- indexable inserts, Ø25 mm, shank Ø20 mm (Teknik Makina)

Boring bar S20Q SDQCR provides a right‑hand, indexable‑insert holder tailored for medium‑duty turning and finishing tasks where repeatable geometry and short setup times matter.

• Right-hand cutting direction
• Cutting diameter Ø25 mm
• Shank diameter Ø20 mm
• Compatible with DC-- 11T3 inserts

High stability for repeatable turning performance

The combination of a Ø25 mm cutting diameter and a Ø20 mm shank delivers a compact but rigid toolbody that reduces deflection during cuts. Reduced vibration improves tool life and helps to maintain tolerances across series production — a clear advantage where process stability is essential. The geometry supports controlled chip formation and contributes directly to consistent surface quality and fewer rework cycles.

Quick insert changes and secure clamping to keep cycles short

Designed for DC-- 11T3 indexable inserts and an SDQC‑style clamping arrangement, the holder enables fast, reliable insert replacement with minimal downtime. The 32 mm cutting height and the defined 107.5° cutting angle ensure correct seat and engagement for standard turning inserts, meaning insert seating is precise and repeatable. Faster changeovers translate into higher machine availability and lower per‑part tooling cost in production environments.

Engineered for productive machining routines

With an overall length of 180 mm and a mass of only 0.435 kg, the tool balances reach and handling, offering good access for internal and external operations while keeping inertia low. The right‑hand cutting orientation suits standard lathe setups and simplifies process planning. The ISO designation S20Q SDQCR denotes the shank class and holder style, helping maintenance and procurement teams to standardise tool sets and reduce inventory complexity.

Practical integration and workshop reliability

The holder’s compatibility with common indexable inserts reduces the number of specialised items in the tool cabinet, which eases logistics and shortens procurement lead times. The compact footprint and robust clamping support repeatable assembly and predictable cutting behaviour on the shop floor. For complex production needs or specific material requirements, technical documentation is available and additional application advice can be provided to ensure the tool matches the machining task.

FAQ

Which inserts fit this holder?
The S20Q SDQCR holder accepts DC-- 11T3 indexable inserts; the SDQC clamping style secures standard turning plates for reliable seating and chip control.

Is the tool suited to internal boring?
Yes — with an overall length of 180 mm and a compact shank, the holder is suitable for many internal turning operations while maintaining rigidity.

What is the shank diameter and why does it matter?
Shank diameter is 20 mm; a stiffer shank reduces deflection under load and improves repeatability, which is vital for close tolerance production.

What cutting direction is provided?
The tool is configured for right‑hand cutting, matching common lathe setups and standard toolpath strategies.

How does the clamping system affect productivity?
The SDQC clamping arrangement allows quick, repeatable insert changes, reducing machine downtime and supporting higher overall equipment effectiveness.
