Corner tool head T430TM — indexable insert holder, 125 mm diameter, 90° cutting angle (Teknik Makina)

Corner tool head T430TM is an indexable insert holder engineered for turning and face operations, intended for use with R390-1806 indexable inserts in demanding production environments.

• 125 mm diameter for wide-reaching cuts
• 90° cutting angle for precise shoulder cuts
• 40 mm shank diameter for secure clamping
• Compatible with Sandvik R390-1806 inserts

High rigidity for consistent, high-quality cuts

The design delivers a predictable cutting geometry based on a 90° cutting angle, which helps maintain dimensional consistency when forming shoulders or square features. The large 125 mm head diameter and the distribution of eight cutting edges increase stability and reduce vibration during interrupted cuts. Such geometry is especially useful in batch production where repeatability matters; users benefit from fewer reworks and improved cycle-time stability thanks to the holder's mechanical stiffness and balanced load distribution.

Straightforward mounting and secure clamping for quick tool changes

Installation relies on standard fastenings and a robust clamping interface: the holder uses a M4x11 Torx screw tightened with a T15 key, and presents a 40 mm shank diameter for firm seating in common tool posts or turrets. This configuration permits fast, reproducible set-ups and reduces downtime during insert changes or re-indexing. The straightforward fixing method is compatible with common workshop workflows, enabling maintenance teams to swap inserts and resume machining with minimal adjustment effort.

Engineered compatibility and dependable weight-to-rigidity ratio

Designed specifically for R390-1806 indexable inserts from Sandvik, the tool head integrates with established insert geometries to exploit chip control and edge life. The component's mass of 3.558 kg and compact overall length of 62 mm contribute to a favourable rigidity-to-overhang balance, supporting heavier cuts without excessive deflection. Specified tolerances and the selection of fastening hardware provide a basis for long-term reliability in series production or demanding single-part manufacture.

FAQ

Which inserts are compatible with this holder?
The corner tool head T430TM is designed for use with R390-1806 indexable inserts and is listed as compatible with Sandvik insert geometries.

What fastening hardware is required for mounting?
Mounting uses an M4x11 Torx screw and requires a T15 key; these specifications are standard for the T430TM and ensure secure clamping.

What shank diameter is required in the tool post?
The T430TM has a 40 mm shank diameter, which should be matched by the machine's tool holder or adapter to achieve correct seating and rigidity.

How many cutting edges does the head provide and what is the benefit?
The holder features eight cutting edges; this distribution enhances stability and aids in even wear distribution during shoulder machining.

What are the dimensional attributes to consider for fixture planning?
Key dimensions for planning are the 125 mm head diameter, overall length of 62 mm and the 40 mm shank diameter of the T430TM; these values guide clearance and overhang calculations.
