100mm Corner Tool Head for AP-- 1604 Indexable Inserts L52mm With Internal Coolant, 90° - Teknik Makina

Take advantage of a rigid 100 mm cutting head with internal coolant and a precise 90° cutting angle to maintain stable cycle times and extend insert life; order the component directly via Metav Werkzeuge or consult our experts for application-specific advice.

Corner turning head — 100 mm diameter, internal coolant (Teknik Makina)

The Corner turning head for AP-- 1604 indexable inserts is designed for square-shoulder turning and external profiling on lathes, offering coolant-through capability for improved chip control and tool life.

• 100 mm diameter head
• Internal coolant supply
• 90° cutting angle for square shoulders
• Compatible with AP-- 1604 inserts (Korloy)

Improve process stability with a rigid 100 mm design

A larger tool head diameter increases stiffness and reduces deflection during heavy cuts, which leads to more consistent part tolerances and fewer reworks. The 100 mm dimension is engineered to stabilise cutting forces and to support repeatable programme times; this contributes to predictable throughput in production environments. By choosing a robust head, downtime from chatter-related quality issues is reduced and cycle reliability is enhanced.

Coolant-through routing that extends insert life

The built-in internal coolant channel delivers cutting fluid directly to the cutting edge, improving cooling and chip evacuation. This targeted supply reduces temperature peaks at the cutting edge, which slows wear and maintains edge geometry over longer tool life. For materials prone to thermal softening or difficult-to-manage chips, the coolant-through feature supports higher metal removal rates while protecting the insert grade and substrate.

Purposeful geometry for accurate shoulder turning

With a 90° cutting angle, the head is optimised for square-shoulder operations and facing tasks where perpendicular contact is required. The geometry enables clean transitions between faces and shoulders, reducing burr formation and minimising secondary finishing. The head accepts AP-- 1604 indexable inserts, a common insert family that balances economy and cutting performance for a wide range of steel and non-ferrous applications.

Fewer tool variants through broad compatibility

Compatibility with Korloy AP-- 1604 inserts and a standard fastening system simplifies inventory management. The head accommodates multiple cutting edges and is secured with an M4x10 Torx screw using a T15 key, making assembly and insert changes straightforward for trained shop staff. Consolidating holders around this interface helps reduce the number of different tool bodies required across turning applications.

Practical dimensions and handling for workshop use

The compact overall length of 52 mm and a mass of 1.532 kg make the head easy to mount while providing the mass necessary for damping vibrations. The unit features a multi-insert arrangement supporting up to 8 engagement positions, useful for operations requiring distributed cutting forces or sequential indexing. The design balances accessibility for maintenance with the rigidity demanded in production turning.
