80mm Corner Tool Head For APMT 11T3 Indexable Inserts, 90° Cut Angle, 8 Cutting Edges, 27mm Shank Diameter - Teknik Makina

High rigidity from a 27 mm shank and a true 90° cutting angle ensures precise, repeatable corner cuts; compatibility with APMT 11T3 indexable inserts keeps tooling costs predictable — order the T256TM Corner Turning Head directly via Metav Werkzeuge or ask our consultants if needed.

T256TM Corner Turning Head — Angle Tool Head for APMT 11T3 Inserts, 90° Cutting Angle (Teknik Makina)

The T256TM Corner Turning Head is an angle tool head engineered for orthogonal turning operations using APMT 11T3 indexable inserts, providing a compact mounting solution for medium‑duty CNC turning applications.

• 90° cutting angle for orthogonal turning
• 27 mm shank diameter for rigid mounting
• Compatible with APMT 11T3 indexable inserts
• Torx screw M2.5 x 5.5, key size T8

Consistent edge engagement for accurate shoulders and faces

The compact head geometry and 90° cutting angle are designed to deliver straight, repeatable shoulder and face cuts under typical shop conditions. A rigid 27 mm shank minimises deflection during cutting, which reduces rework and improves first‑pass accuracy. For users converting from brazed or brazed‑tip tooling, this holder allows faster tool changes and predictable cutting performance when fitted with the correct APMT 11T3 indexable inserts.

Quick set‑up and clear compatibility for reduced downtime

Installation and indexing are straightforward thanks to the defined clamping interface and the specified Torx fastener dimensions. The head accepts standard APMT 11T3 format inserts (Korloy listed as compatible), enabling easy sourcing from common carbide vendors and simplifying inventory. The Torx fastening specification (M2.5 x 5.5) and required key size (T8) are stated to help preparation of the correct workshop tools and avoid delays during tool changes.

Designed for dependable workshop performance

With a compact overall length and a Ø 80 mm head, the unit provides a space‑efficient solution where clearance is limited. The specified eight cutting edges and balanced mass (approx. 1.115 kg) support stable running at moderate spindle speeds, while the solid construction contributes to a long service life under normal operating conditions. The result is predictable cycle times and a stable surface finish on turned parts, reinforcing efficient production planning.

FAQ

Which inserts fit this tool head?
The T256TM accepts APMT 11T3 format indexable inserts; Korloy is listed as a compatible insert manufacturer for this holder.

What is the shank diameter and how does it affect rigidity?
The shank diameter is 27 mm; a larger shank increases rigidity and reduces deflection during orthogonal turning operations.

What is the cutting geometry of the head?
The head provides a 90° cutting angle, optimised for straight shoulder and face turning where a square approach is required.

Which Torx specification is required for the clamping screw?
The clamping screw specification is M2.5 x 5.5 and the Torx key size indicated is T8, which should be used for proper tightening.

Is the head suitable for compact assemblies with limited clearance?
Yes; the Ø 80 mm head and 50 mm overall length make the unit suitable where space is restricted while still offering a stable cutting platform.
