S520TM Shank Milling Cutter – 25 mm shank, for R390‑1704 indexable inserts (Teknik Makina)

The S520TM shank milling cutter is a shank-mounted milling body designed for use with R390‑1704 indexable inserts, providing a compact, serviceable solution for workshops and production cells where fast insert changes and consistent results are essential

• Compatible with R390‑1704 Sandvik inserts
• 25 mm shank diameter for robust clamping
• Two cutting edges with 90° cutting angle
• Torx screw M3.5x8.5, Torx key T15

Stability and machining accuracy for repeatable results

A robust 25 mm shank and a balanced overall construction deliver improved stability during milling, which reduces chatter and supports consistent surface finish. With an overall length of 150 mm and a mass of 0.536 kg, the tool body is designed to keep rotational inertia moderate while providing sufficient reach for typical milling operations. These design choices translate into predictable cutting behaviour, reduced rework and longer life for both the cutting body and the inserts.

Efficient indexable-insert system that lowers operating costs

The holder is configured specifically for R390‑1704 indexable inserts and is compatible with Sandvik plate geometries, enabling rapid re-indexing and minimal downtime. The cutter provides two cutting edges and a 90° cutting angle, delivering a reliable cutting geometry for slotting and peripheral milling tasks. A 55 mm cutting length allows a useful engagement range while keeping the insert support rigid, which benefits tool life and cost per part through straightforward insert replacement rather than full-bodied regrinding.

Fast insert changes and secure fastening to reduce downtime

Insert clamping and replacement are simplified by the use of a Torx M3.5x8.5 fastening screw and a T15 key interface, which standardises the maintenance procedure and speeds up changeovers. This clear mechanical specification ensures service technicians and operators can perform insert changes quickly and repeatably, lowering machine idle time and improving net productive hours on the shop floor.

Practical advantages for procurement and workshop logistics

Standardisation on a holder that accepts widely used inserts reduces the number of special spare parts required and simplifies stock management without compromising process capability. The S520TM’s compatibility with established insert formats means fewer unique tool bodies to order and an easier spare-parts strategy. For purchasing and production planning, this translates into a leaner tool inventory and faster response to varying production demands.
