S251TM Shaft Milling Cutter by Teknik Makina – 40 mm Diameter · 32 mm Shank (for APMT 1604 Inserts)

The S251TM is a shaft milling cutter tailored for versatile face and slot milling using APMT 1604 indexable inserts, suited to industrial and workshop CNC applications.

• 40 mm cutter diameter for broad material removal
• 32 mm hardened shank for high rigidity
• Compatible with APMT 1604 indexable inserts
• Four cutting edges for balanced machining

Reliable performance for high‑productivity milling

The S251TM is engineered to deliver consistent results in series production and jobbing shops. With a 32 mm shank and a 40 mm diameter, the tool provides a stable cutting platform that reduces chatter and enables higher material removal rates. The four flutes guarantee even load distribution, which improves surface finish and tool life. Where cycle time and repeatability matter, this cutter contributes to predictable machining results through its rigid design and balanced geometry.

Economical indexable system and quick insert changes

Designed for APMT 1604 indexable inserts, the cutter offers an economical approach to tool management: insert replacement is faster and less costly than resharpening solid tools. The cutter retains inserts with an M4x10 Torx screw, tightened with a T15 key, ensuring reliable clamping and straightforward maintenance. Less downtime for tooling changes means increased uptime on the machine, and compatibility with Korloy inserts widens sourcing options for supplies and grades.

Application scope and machining advantages

This milling solution excels in general face milling and light slotting across common industrial alloys when correct cutting data are applied. The 90° cutting angle supports square shoulder operations and efficient side cutting. The tool’s attributes make it particularly suitable for work requiring a balance of material removal and surface quality; hard finishing or heavy roughing should be planned according to insert geometry and machine power to preserve tool life.

Practical design for workshop integration

Handling and mounting have been considered: the cutter’s 150 mm overall length and 55 mm cutting length allow comfortable reach while maintaining rigidity close to the spindle. At a weight of 1.294 kg, it is straightforward to fit and balance in standard toolholders. The combination of mechanical clamping via the Torx screw and proven insert form factors simplifies inventory and training requirements, supporting efficient production workflows.

FAQ

Which inserts fit this cutter?
The S251TM accepts APMT 1604 indexable inserts; Korloy grades are listed as compatible and common industry grades can be selected for application needs.

How is the insert secured?
Inserts are fixed with an M4x10 Torx screw, tightened using a T15 key, which provides reliable clamping suitable for standard milling forces.

What operations is this cutter best suited to?
The tool is designed for face milling and light slotting where a 90° cutting angle and four cutting edges provide balance between productivity and surface quality.

What are the key dimensions for toolholder selection?
Important dimensions: 32 mm shank diameter, 40 mm cutter diameter, 55 mm cutting length and 150 mm overall length — select a holder compatible with a 32 mm shank.

Is the cutter suitable for heavy roughing?
Heavy roughing demands consideration of insert grade, machine power and cutting parameters; the S251TM offers rigidity, but optimum performance for heavy cuts requires matching insert geometry and speed/feed settings.
