Corner turning head T404-1TM – 50 mm diameter, internal coolant (Teknik Makina)

The Corner turning head T404-1TM is a compact indexable head for corner turning, engineered for coolant-through performance and reliable use with R390 17 inserts in demanding workshop applications

• 50 mm diameter for compact turning
• Internal coolant for improved chip evacuation
• Compatible with R390 17 Sandvik inserts
• 22 mm shank and 45 mm overall length

Predictable results through coolant-through chip control

The toolhead provides internal coolant directly to the cutting zone, which supports consistent chip evacuation and reduces built-up edge during interrupted cuts. With a true 90° cutting angle and support for R390 17 indexable inserts, the head secures repeatable corner geometry and surface quality. Engineers will value the combination of coolant routing and rigid seating, which together reduce rework and help maintain cycle-time stability in series production.

Fast insert changes and system compatibility

Designed for quick maintenance, the head uses a T15 Torx interface and M3.5x8.5 fixing screws for secure insert clamping and predictable torque values. The 22 mm connection diameter and 45 mm overall length enable straightforward integration into common modular toolholders, shortening setup time on the shop floor. At 0.591 kg the component is easy to handle while remaining robust enough for daily use, aiding efficient changeovers and minimising downtime.

Built for reliable workshop performance and wide compatibility

Manufactured by Teknik Makina, the T404-1TM indexable head pairs with Sandvik R390 17 inserts to cover a broad range of corner-turning tasks where stability and finish matter. The compact form factor and straightforward fixing system reduce spindle overhang, improving rigidity and tool life. Specified components and familiar interfaces simplify procurement and spare-parts planning, supporting predictable production runs and easier maintenance planning.
