Boring bar S32T MTUNR (MTUN for TNMG indexable inserts) — Teknik Makina, Ø40 × 300 mm

The Boring bar S32T MTUNR is a right‑hand turning tool designed to use TNMG 1604 indexable inserts, intended for general workshop and light production turning applications.

• Right-hand turning configuration
• For TNMG 1604 indexable inserts
• Shank Ø 32 mm, overall length 300 mm
• Robust construction, weight 1.835 kg

Consistent right‑hand cutting for predictable cycles

The right‑hand geometry and dedicated insert pocket make the tool a practical choice where cycle stability matters. By accepting TNMG 1604 indexable inserts, the bar enables quick insert changes and consistent contact geometry; this reduces downtime compared with brazed or solid tools and supports repeatable surface quality. The ISO designation S32T MTUNR reflects the standardised shank and pocket arrangement, which simplifies toolholder selection and replacement planning.

Shank and length tuned for stiffness and access

With a shank Ø32 mm and an overall length 300 mm, the design targets a balance between rigidity and reach. The Ø40 mm body and cutting height 60 mm contribute to reduced deflection when clamped in standard tool posts, improving dimensional accuracy over extended cuts. The mass of the assembly (approx. 1.835 kg) also helps damp vibration in interrupted cuts, translating into improved tool life for inserts and steadier cycle times on batch production runs.

Productivity gains from indexable‑insert tooling

The bar’s seating for TNMG inserts and the 93° cutting angle deliver controlled chip flow and predictable cutting forces. Using indexable inserts minimises secondary operations for regrinding and enables rapid changeover, which supports a favourable cost‑per‑part calculation in small to medium series. The configuration is particularly suitable where toolholders must be swapped quickly to maintain machine throughput while retaining geometrical accuracy.

Procurement advantages and workshop fit

Sourced under the Teknik Makina designation and supplied as a standard ISO shank variant, this turning bar integrates into established tooling systems with minimal retooling. Metav Werkzeuge’s distribution ensures access to spare inserts and complementary holders from stock, underlining the practical advantage of centralised procurement. The product supports a steady production flow by combining indexable inserts convenience with a robust shank geometry for everyday machining tasks.

FAQ

Which inserts fit the bar? The bar accepts TNMG 1604 indexable inserts; the S32T MTUNR configuration is designed to locate and secure those inserts reliably.

What are the key dimensions to check for toolholder compatibility? Check the shank Ø32 mm, the overall length 300 mm and the toolpost capacity; these determine clamping fit and overhang for the Teknik Makina S32T MTUNR (SKU K444TM).

Is the cutting direction right‑hand or left‑hand? This turning bar is configured for right‑hand cutting and is optimised for conventional right‑hand turning operations.

How does the 93° cutting angle affect machining? The 93° cutting angle gives controlled chip formation and stable cutting forces, aiding surface finish and repeatability when used with the recommended TNMG inserts.

Are inserts and clamping screws included? The product is specified to accept TNMG 1604 inserts; check the product listing for scope of delivery and whether inserts or fixing screws are supplied with the S32T MTUNR.
