Take advantage of a compact, rigid tool head that combines a 90° cutting angle with compatibility for standard APMT 11T3 indexable inserts to produce accurate perpendicular faces and reduced setup time — order directly via Metav Werkzeuge or consult our tooling advisers for integration into existing toolholders.

Corner milling head T250TM – 90° head for APMT 11T3 inserts (Teknik Makina)

The Corner milling head designed for precise 90° shoulder machining and reliable fit with standard APMT 11T3 indexable inserts, suitable for general CNC milling and finishing of perpendicular faces.

• Corner milling head for APMT 11T3 inserts
• 90° cutting angle for square shoulders
• 16 mm shank for secure toolholder fit
• Secured with M2.5x5.5 Torx screw

Accurate right‑angle faces with indexable inserts

The compact head provides a 90° cutting angle that ensures true square shoulders and consistent contact geometry on machined parts. Matched to the APMT 11T3 insert form, the head allows rapid replacement of cutting edges while keeping clamping repeatability high. For production environments where setup time and workpiece tolerances matter, this configuration reduces manual dressing and aligns with standard indexable tooling workflows to maintain throughput and part conformity.

Rigid design for stable machining and extended tool life

A firm connection via the 16 mm shank and a compact envelope of Ø 40 mm with an overall length of 40 mm gives the head the stiffness required for short‑overhang operations. The low mass (approx. 0.22 kg) helps reduce centrifugal effects and vibration at higher spindle speeds, resulting in improved surface finish and longer insert life. The construction supports repeatable runs on CNC lathes and milling centres where stability and micrometre‑level consistency translate directly into lower rework rates.

Straightforward clamping and quick servicing

Insert retention is provided by a M2.5x5.5 Torx screw, tightened with a T8 key, so insert changes are fast and tool maintenance is uncomplicated. The head is compatible with Korloy inserts in the APMT 11T3 format and can be stocked as a single, reliable component to reduce tooling inventory complexity. Supplied as a compact, ready‑to‑mount head, the unit is designed to integrate smoothly into existing toolholder systems and to minimise downtime during changeovers.
