Shank milling cutter S474TM — indexable-insert milling cutter, Ø21 mm, 3-flute (Teknik Makina)

The Shank milling cutter S474TM is an indexable-insert cutter designed for general milling operations with replaceable 4NKT06 inserts, offering long reach and stable clamping for industrial machining tasks

• Compatible with 4NKT06 Taegutec inserts
• Ø21 mm diameter, 3 cutting edges
• Shank Ø20 mm, 200 mm overall length
• Secured with M3x6.5 Torx screw (T8 key)

Reliable rigidity for repeatable results

The S474TM is built around a Ø21 mm cutting head and a Shank Ø20 mm, which together provide high rigidity and reduced deflection in axial and radial loads. The combination of a short 25 mm cutting length and a 200 mm overall length balances accessibility with stability; long-reach operations remain possible without excessive chatter. Using indexable inserts such as the 4NKT06 type means the cutting geometry can be restored instantly by rotating or replacing an insert, reducing downtime and lowering the ongoing cost per cut compared with solid-tool regrinding.

Fast changeover and secure clamping for production environments

Clamping is achieved with an M3x6.5 Torx screw tightened using a T8 key, providing a compact, repeatable fastening method that is straightforward to service on the shop floor. The cutter’s three-flute layout delivers a stable cutting sequence and smooth engagement, which is particularly useful when working with interrupted cuts or mixed-geometry components. With a mass of 0.524 kg the tool offers a reassuring mechanical feel during handling and set-up, while the compatibility with Taegutec indexable inserts ensures broad availability of chipbreakers and grades for a variety of workpiece materials.

Practical benefits for procurement and maintenance

Adopting this style of indexable-insert milling system supports predictable inventory and maintenance planning: spare inserts are low-cost and easy to stock, and the modular design reduces the number of complete cutters required. For purchasing teams the clear separation of cutter body and consumable inserts simplifies cost tracking and extends the service life of the holder. When mounted and set up correctly, the S474TM delivers consistent tool life and repeatable part quality, which in turn helps to optimise cycle times and reduce rework in batch production.

FAQ

How are the inserts secured in the S474TM? The inserts are retained in the cutter body and clamped by the indexable-insert pocket; the cutter itself is secured with an M3x6.5 Torx screw, tightened using a T8 key, ensuring repeatable seating.

Which insert type fits the cutter? The S474TM accepts 4NKT06 indexable inserts; the tool is compatible with Taegutec variants in that ISO designation.

Is the S474TM suitable for long-reach milling? With a 200 mm overall length and a 25 mm cutting length, the cutter provides extended reach while maintaining reasonable stiffness for typical shop-floor operations.

What are the advantages of using indexable inserts with this cutter? Indexable inserts restore cutting geometry quickly, reduce downtime, and lower per-cutting-edge costs compared with regrinding solid tools; the S474TM’s design supports rapid insert changes.

Can the cutter be used with different insert grades? Yes, the S474TM accepts standard 4NKT06 insert grades from manufacturers such as Taegutec, allowing selection of grades for wear resistance or toughness according to the workpiece material
