Corner turning head with internal coolant — compatible with R390 18 indexable inserts (Teknik Makina)

Corner turning head for R390 18 indexable inserts — a compact tool head engineered for precision turning and facing operations on CNC lathes, offering internal coolant and secure Torx clamping for reliable production use.

• 63 mm diameter for stable cutting
• Internal coolant for improved chip evacuation
• Compatible with R390 18 Sandvik inserts
• 45 mm overall length with 90° cutting angle

Higher throughput through rigid, coolant-fed cutting

The robust design of this tool head prioritises cutting stability and consistent cycle times. With a 63 mm diameter and a 90° cutting angle, the head provides a secure platform for heavy shoulder cuts and facing passes, reducing vibration and improving surface finish. The presence of internal coolant directs cutting fluid precisely to the cutting zone, which helps to lengthen insert life and maintain cutting forces within expected limits. This combination of rigidity and targeted cooling enables higher feeds and longer uninterrupted runs, supporting measurable productivity gains in batch production.

Proven compatibility and quick, repeatable set-ups

Fitting directly to the popular insert family R390 18, the head accepts Sandvik-specified inserts, simplifying tooling procurement and inventory. The compact 45 mm overall length and a 22 mm shank interface allow straightforward integration into existing tool posts. Fixing employs a Torx T15 engagement and an M4x10 screw for repeatable, secure clamping of the insert seat; this reduces setup times and minimises the risk of incorrect torque during changeovers. The standardised interface therefore supports rapid changeovers and predictable process parameters.

Precision engineering that benefits the workshop

Engineered for balance and ease of handling, the unit weighs approximately 0.49 kg, keeping inertial loads low for better spindle and carriage response. The head incorporates five cutting edges, arranged to deliver consistent engagement and distribution of cutting forces where applicable. For less experienced operators, internal coolant and a positive clamping system translate directly into fewer interruptions for manual cooling or adjustments. The compact form factor and clear mounting scheme help maintain machine ergonomics and lower the barrier to implementing high-precision operations in diverse shop-floor environments.

Practical advantages across turning applications

Whether used for facing, profiling or shoulder turning on CNC lathes, the tool head delivers predictable behaviour and straightforward maintenance routines. The SKU T424-1TM identifies the specific configuration, which is manufactured by Teknik Makina and designed for reliable interchangeability with Sandvik insert systems. Reduced downtime from quicker insert swaps, combined with improved chip control from the internal coolant, means less interruption to production and fewer consumable changes per shift—advantages that contribute directly to lower unit costs and steadier throughput.

FAQ

What insert family does this tool head accept?
The head accepts the R390 18 family of indexable inserts, making it compatible with widely available Sandvik inserts for straightforward tooling selection.

How does internal coolant improve machining with this head?
Internal coolant delivers cutting fluid directly to the cutting edge, which the corner turning head uses to reduce heat, improve chip evacuation and extend insert life.

Is the mounting compatible with standard tool posts?
The head uses a 22 mm shank interface and a compact 45 mm overall length designed for easy integration into common CNC lathe tool posts.

Which fixing system secures the insert in place?
Insert clamping is achieved with a Torx T15 engagement and an M4x10 fixing screw, offering reliable and repeatable clamping torque.

Can the head be identified for reordering or stock management?
Yes — the specific configuration is listed under SKU T424-1TM for accurate reordering and inventory control.
