Shank milling cutter S538TM — 40 mm diameter, for R390-1704 indexable inserts by Teknik Makina

The Shank milling cutter S538TM is a purpose-built tool for indexable-insert milling operations, optimised for face and shoulder work with R390-1704 inserts

• Compatible with R390-1704 indexable inserts
• 40 mm cutting diameter for broad material removal
• 32 mm shank diameter for stable clamping
• Four cutting edges; 90° cutting angle

Stable setup for higher metal removal rates

This cutter combines a 32 mm shank with a 40 mm cutting diameter to deliver a rigid toolholder interface and predictable cutting behaviour. The heavy-duty shank diameter reduces vibration and runout, which in turn extends insert life and improves surface finish. With a 90° cutting angle, the geometry is suited to shoulder milling and heavy passes where a square cut is required. Engineers benefit from consistent chip load and reduced rework, while production planners see fewer stoppages caused by upset tooling.

Fast insert changes and secure fastening to cut downtime

Designed specifically for the Sandvik insert family, the cutter accepts R390-1704 indexable inserts and is secured with a Torx M3.5x8.5 screw tightened using a T15 key. This proven fastening method provides reliable clamping force and straightforward maintenance: replacing a worn insert is a quick operation that minimises machine downtime. The combination of indexed inserts and standard Torx hardware supports predictable uptime and easier inventory management for tooling departments.

Reach, balance and workshop practicality for daily use

With a 200 mm overall length and a 55 mm cutting length, the tool offers a good balance between reach and stiffness for many common milling setups. The cutter features four cutting edges, enabling efficient material removal while maintaining tool life through indexed regrinds or replacements. At 1.272 kg, the assembly is straightforward to handle during tool changes yet substantial enough to maintain momentum in heavy cuts. These characteristics make the tool an effective choice where repeatability, quick serviceability and integration into existing Sandvik-insert workflows are priorities.

FAQ

Which indexable inserts fit this cutter?
The cutter is specified for R390-1704 indexable inserts; Sandvik inserts of this designation are compatible with the S538TM.

What is the shank diameter and why does it matter?
The 32 mm shank diameter gives the tool a rigid connection to the holder, reducing vibration and improving both finish and insert life for the S538TM.

How many cutting edges does the tool have?
This shank milling cutter features four cutting edges, which balances material removal rate with stability during milling.

What fastening hardware is required for insert changes?
Insert clamping on the S538TM uses a Torx M3.5x8.5 screw and requires a T15 key for secure and repeatable tightening.

For which milling tasks is this tool recommended?
The 90° cutting angle and the tool’s dimensions make it particularly suitable for face and shoulder milling where square shoulders and efficient chip evacuation are needed.
