Corner cutter head T578-1TM — 50 mm diameter, internal coolant (for R390 11 indexable inserts)

The Corner cutter head for R390 11 indexable inserts is designed for precise corner and shoulder machining in turning and milling setups, with a compact overall length for close‑quarter operations

• 50 mm diameter for stable cutting
• Internal coolant for better chip evacuation
• Compatible with Sandvik R390 11 inserts
• 90° cutting angle for corner machining
• 40 mm overall length, compact design

Maximise process stability with targeted coolant delivery

The combination of a 50 mm diameter body and internal coolant creates a reliable interface between tool and workpiece, reducing thermal growth and improving repeatability in serial production. Internal coolant channels actively direct cutting fluid to the insert rake face, which supports controlled chip formation and extends insert life. For workshops seeking measurable uptime gains, the application of targeted coolant contributes directly to more consistent component tolerances and fewer unscheduled tool changes.

Robust mounting and indexable insert economy

Mounting is achieved for R390 11 indexable inserts, a common Sandvik configuration that simplifies supply and inventory. The tool uses a M2.5x7 Torx screw tightened with a T8 Torx key to secure each insert; this proven clamping reduces micro‑movement and maintains cutting geometry under load. With six cutting edges available on the indexable parts and an incorporated 90° cutting angle, the head supports efficient corner engagement and quick insert indexing, which lowers per‑component tooling cost and shortens downtime during maintenance.

Compact dimensions for tight applications and machine compatibility

The head’s 40 mm overall length and low mass (0.355 kg) make it suitable where access is limited or where minimal overhang is required for rigidity. That compact footprint helps maintain cutting parameters closer to design values and reduces vibration in medium‑duty turning and milling tasks. Delivered as a ready‑to‑mount unit from Teknik Makina, the assembly is aimed at production environments that demand both repeatable performance and straightforward serviceability.
