Angle Tool Head for R390 18 Indexable Inserts — 80 mm, Internal Coolant (Teknik Makina)

The Angle Tool Head is a compact turning head engineered for square-shoulder and face-turning operations with R390 18 indexable inserts, offering a short overall length and integrated coolant supply for controlled machining.

• 80 mm diameter for stable machining
• Internal coolant for improved chip control
• Compatible with R390 18 Sandvik inserts
• 90° cutting angle for square-shoulder work

Increased rigidity for consistent shoulder quality

A substantial 80 mm diameter body combined with a 52 mm overall length reduces overhang and vibration during heavy shoulder cuts, delivering consistent surface finish and repeatable geometry. The component’s mass (approx. 1.081 kg) and compact design support higher process stability, which translates into fewer rejects and less rework. By reducing chatter and deflection, cycle times become more predictable and tool life for the indexable inserts is preserved, making the head suitable for demanding batch production environments.

Targeted cooling to protect inserts and process reliability

The integrated internal coolant directs lubricant and coolant precisely to the cutting zone, improving heat dissipation and chip evacuation. For indexable systems this means extended flank and crater life on the insert, reduced thermal deformation and more reliable tool performance over longer cycles. Explaining the term: internal coolant supplies fluid through the tool body to the insert seat, unlike external flushing which can miss the contact zone; this focused supply often enables higher stable cutting parameters and cleaner chips at the point of contact.

System compatibility and quick maintenance

Designed for the R390 18 insert format and specified to accept Sandvik supplier inserts, the head simplifies tooling inventory where common insert standards are used. Fast insert changes are supported by the supplied screw specification (M4x10) and the required Torx T15 key interface, enabling rapid service intervals and minimal downtime. The head accommodates six cutting edges in its system architecture and a 90° cutting angle, which is particularly effective for square shoulders and external chamfering tasks.

Workshop integration and production benefits

Manufactured by Teknik Makina, this turning head is intended for easy integration into existing turret and toolpost arrangements, providing a compact footprint and industry-standard interfaces. The combination of a short overall length and targeted coolant reduces the need for elaborate fixture changes while improving process repeatability. For procurement and operations managers the head represents a pragmatic choice where predictable performance, reduced cycle variability and simplified maintenance routines are priorities.

FAQ

Is this head compatible with all R390 18 insert variants? The Angle Tool Head accepts the R390 18 insert geometry; specific insert grades and chipformers from Sandvik should be checked against process requirements for best results.

Does the head provide internal coolant to every insert position? Yes, the internal coolant channel supplies fluid to the cutting zone, improving thermal control and chip evacuation for the insert seat on this Teknik Makina turning head.

What tool is required to change the insert screws? Insert retention uses an M4x10 screw with a Torx T15 interface; a T15 Torx key is specified for secure and quick insert replacement.

Can the head be used for square-shoulder machining on small lathes? The compact 52 mm overall length and 80 mm body are designed for reduced overhang; suitability for a particular turret or toolpost should be confirmed against machine envelope and clamping specifications.

Where is the product manufactured and how is it identified? The component is produced by Teknik Makina and is supplied under SKU T426-1TM for order and inventory tracking.
