Corner tool head T404TM — 90° indexable insert holder, 22 mm shank (Teknik Makina)

A compact Corner tool head T404TM engineered for right-angle turning and shoulder work using R390-1704 indexable inserts, suitable for CNC lathes and turning centres

• 90° cutting angle for accurate shoulder machining
• Compatible with R390-1704 Sandvik inserts
• 22 mm shank for standard toolholder systems
• M3.5x8.5 Torx screw fixed, T15 key required

Consistent right-angle performance for repeatable parts

The holder’s 90° cutting angle provides a defined geometry for shoulder and profiling operations, ensuring consistent contact between insert and workpiece. With a 50 mm head diameter the assembly offers controlled stiffness that supports stable cutting forces and reduced chatter. This geometry simplifies cycle planning on turning centres and can improve first-pass yield when producing stepped shafts or grooves.

Quick insert changes and low-maintenance fastening

Designed for routine workshop handling, the head accepts R390-1704 indexable inserts and a M3.5x8.5 Torx screw, requiring a T15 key for secure clamping. The combination of standard screw format and common insert series reduces downtimes during regrinds or tool changes. The compact 45 mm overall length and 22 mm shank aid accessibility in tight tool posts while preserving a low system inertia for snappier tool changes.

Reliable fitment and balanced handling in the toolpost

Compatibility with Sandvik insert types and a practical mass of 0.591 kg make this head straightforward to integrate into established tool setups. The five cutting edges provide multiple index positions for prolonged service intervals. Supplied geometry supports predictable chip flow and repeatable set-up, which in turn lowers scrap rates and simplifies operator procedures on production lines.
