S512TM Insert Milling Cutter — 30 mm diameter, for R390‑1704 indexable inserts (Teknik Makina)

The S512TM is an indexable insert milling cutter designed for medium‑duty facing and slotting operations, compatible with the R390‑1704 insert system and intended for use where fast insert indexing and reliable clamping are required

• 30 mm cutting diameter
• 25 mm shank for rigid clamping
• Compatible with R390‑1704 Sandvik inserts
• Three cutting edges for balanced cutting

Stable insert system for predictable performance

The tool is built around the R390‑1704 insert interface, a widely used standard that simplifies stocking and index changes; the use of indexable inserts ensures constant cutting geometry without full regrinding. Fast securement is achieved with an M3.5x8.5 Torx screw and a T15 key interface, which keeps setup times low and repeatability high. These characteristics translate into fewer interruptions on the shop floor and predictable cycle times, supporting tighter production planning.

Rigidity and geometry tuned for consistent metal removal

A 25 mm shank paired with a 30 mm cutter body gives improved clamping stability and reduced chatter in many fixture arrangements. The cutter features three cutting edges and a 90° cutting angle, with a 45 mm effective cutting length and 120 mm overall length; the balanced geometry promotes even load distribution across inserts and a uniform surface finish. The assembly weight of approximately 0.461 kg contributes to controlled spindle load while maintaining sufficient mass for damping, making the tool suitable for stable milling operations where dimensional consistency matters.

Easy handling, controlled life‑cycle and workshop integration

Changeover is simplified by standardised insert geometry and the Torx fastening solution, lowering maintenance time and inventory complexity. The modular concept of indexable tooling encourages economical replenishment: only the worn inserts are replaced rather than the entire cutter body. Combined with Metav’s logistical reliability and broad product range, the cutter supports efficient workshop management and reduces supplier fragmentation, enabling longer production runs with consistent quality and less administrative overhead.

FAQ

Which inserts fit this cutter?
The cutter accepts R390‑1704 indexable inserts; replacement inserts from the R390‑1704 family match the pocket geometry and clamping method used on the S512TM.

How are the inserts secured?
Inserts are fastened with an M3.5x8.5 Torx screw; a T15 key is specified for secure tightening on the S512TM.

What clamping diameter is required?
A 25 mm shank is specified for the S512TM, so holders or collets that accept a 25 mm shank are required for proper mounting.

How many cutting edges are available on the tool body?
The S512TM is equipped with three cutting edges, providing a balance between material removal rate and surface finish.

Is the cutter suitable for rapid insert indexing?
Yes, the standard R390‑1704 interface and Torx fastening enable quick insert changes and straightforward indexing on the S512TM.
