Corner milling head T428-1TM for R390 18 indexable inserts — 100 mm diameter, internal coolant (Teknik Makina)

Corner milling head T428-1TM designed for face and shoulder machining with R390 18 indexable inserts, providing coolant-fed cutting and high rigidity in production environments.

• 100 mm diameter for stable cutting
• Internal coolant for improved chip evacuation
• Compatible with R390 18 Sandvik inserts
• 90° cutting angle for square shoulder machining

Stable, repeatable cutting for production environments

The corner milling head is engineered to deliver consistent results in batch and series production. With a 100 mm diameter and a compact overall length of 52 mm, the geometry provides increased stiffness and reduced vibration during heavy engagement cuts. Compatibility with R390 18 indexable inserts (Sandvik-compatible) allows the use of widely available grades and corner radii, simplifying process planning. The robust mass (1.595 kg) contributes to stable spindle loads and predictable cutting forces, which supports repeatable surface quality and machining tolerances.

Integrated coolant for longer tool life and reliable surface finish

Built-in internal coolant channels feed cutting fluid directly to the insert edge, improving chip control and reducing thermal load at the cutting zone. This targeted coolant delivery helps maintain cutting edge integrity, delays wear, and can extend indexable insert life under continuous operation. Better chip evacuation also lowers the risk of re-cutting, leading to more consistent part finishes and fewer unplanned interventions on the machine, which benefits cycle-time reliability across shifts.

Simple, secure clamping to speed up changeovers

The design focuses on straightforward assembly and secure fixing: fasten the insert with the specified Torx T15 key and M4x10 Torx screws for a firm seat and repeatable insert positioning. The 90° cutting angle is ideal for square shoulder operations, while the compact L52 mm overall length improves access in tighter tool turrets. Together, these features reduce set-up time and support efficient tool changes, helping to minimise downtime in mixed-production environments where flexibility and quick return to cutting are essential.
