Corner tool head T178-1TM – 63 mm diameter, internal coolant, for APKT 1003 indexable inserts

A corner tool head engineered for precise shoulder turning and finishing with APKT 1003 indexable inserts, offering internal coolant and a 90° cutting angle for reliable square-cut performance

• 63 mm diameter for stable setup
• Internal coolant for effective cooling
• For APKT 1003 indexable inserts
• Compatible with Korloy inserts

Reliable square-shoulder performance for production environments

The head is designed to deliver consistent 90° cutting angle results when machining shoulders and faces. The geometry supports accurate perpendicular cuts with minimal deflection, which improves first-pass quality and reduces secondary operations. The robust body geometry combined with a 63 mm tool diameter increases rigidity; this higher stiffness lowers vibration during machining and enhances repeatability across batches. For workshops seeking predictable tolerances on repetitive tasks, the unit’s combination of stiffness and defined cutting geometry translates into time savings and fewer rejected parts.

Effective cooling and chip control for longer insert life

Integrated internal coolant channels feed cutting fluid directly to the cutting edge, aiding heat dissipation and chip evacuation. By directing coolant to the tool–workpiece interface, the system reduces thermal softening of the insert and limits built-up edge formation, extending insert life and maintaining surface finish quality. In practical terms, this reduces tooling intervention and replacement frequency, improving uptime in medium-to-high volume turning tasks. The design supports efficient cooling without additional external fittings, simplifying setup for shops using centralised coolant supply.

Practical handling and service features that speed maintenance

The holder’s total length of 40 mm and the modest mass (0.543 kg) make it straightforward to mount and balance in standard toolposts. Fastener details are standardised: the clamp uses a Torx key T8 and Torx screw M2.5×5.5, which keeps routine insert changes quick and reproducible. The head accommodates multiple cutting edges—listed as seven cutting edges in the specification—delivering flexibility for indexable insert rotations and extended service intervals. These features reduce downtime during shift changes and make the head suitable for both jobbing and light-series production.

Compatibility and application scope explained

This tool head is made for APKT 1003 indexable inserts and is compatible with inserts from Korloy, allowing straightforward integration into existing tooling inventories. The configuration fits applications that require precise shoulder creation, profiling and finishing on cast and alloy steels. The compact design is especially advantageous where close-tool spacing or limited overhang occurs. For users upgrading from single-point tools, the indexable system provides consistent geometry and fast replacement, which benefits quality assurance processes in industrial workshops.

FAQ

What insert type does this head accept?
The corner tool head is designed for APKT 1003 indexable inserts and is compatible with Korloy-manufactured inserts.

Is the head cooled internally or externally?
The tooling features internal coolant, supplying lubricant and coolant directly to the cutting zone to improve insert life and surface finish.

What is the cutting angle and why does it matter?
The tool head has a 90° cutting angle, optimised for square shoulders and perpendicular facing operations where dimensional accuracy and finish are critical.

Which fasteners are required for insert changes?
Insert retention uses a Torx screw M2.5×5.5, serviceable with a T8 Torx key for quick, repeatable insert changes.

Can this head be used in compact toolpost arrangements?
Yes; with a total length of 40 mm and a balanced mass (0.543 kg), the head is suitable for confined setups and reduced overhang situations.
