Indexable Insert Milling Cutter S256-1TM — 25 mm shank, internal coolant (Teknik Makina)

Indexable Insert Milling Cutter S256-1TM is a precision tool for CNC milling operations, designed to accept AP-- 1604 indexable inserts and to improve coolant delivery at the cutting zone

• 25 mm shank diameter
• Internal coolant for improved chip control
• Compatible with AP-- 1604 indexable inserts
• Secured by M4x10 Torx screw (T15)

High-performance milling with stable shank support

The cutter delivers a predictable, high-stability performance thanks to its 25 mm shank and compact 120 mm overall length, which reduce overhang and vibration in most machining set-ups. With two effective cutting edges the tool achieves reliable stock removal while maintaining a consistent surface finish. The combination of a solid shank diameter and compact geometry supports higher feed rates and decreases the need for frequent rework, improving throughput in batch and single-piece production.

Improved coolant delivery and maintenance benefits

Equipped with internal coolant the tool channels cutting fluid directly to the insert flank and the rake face, aiding chip evacuation and reducing heat build-up at the cutting edge. The insert pocket accepts AP-- 1604 indexable inserts (Korloy compatible), which simplifies tool service: worn inserts are replaced quickly rather than regrinding the body. The clamping system uses an M4x10 Torx screw and a T15 key interface for positive torque transmission and straightforward, repeatable insert changes, shortening maintenance cycles and lowering overall tooling costs.

Application-oriented design for modern CNC workflows

Designed for slotting, ramping and peripheral milling tasks, the cutter integrates easily with standard toolholders used in vertical and horizontal machining centres. The internal coolant capability supports operations that demand controlled thermal conditions and better chip flushing, particularly in continuous production environments. Manufactured by Teknik Makina with a focus on compatibility and serviceability, this milling cutter is suitable where quick insert exchange and process reliability are priorities.
