Corner turning head — for R390 18 indexable inserts, 125 mm diameter, internal coolant (Teknik Makina)

Corner turning head designed for precision turning tasks in production and workshop environments, compatible with R390 18 indexable inserts and optimised for coolant-through operation

• 125 mm diameter for extended reach
• Internal coolant feed for reliable chip control
• Compatible with Sandvik R390 18 inserts
• Robust design, 8 effective cutting edges

Enhance machining stability and throughput with a rigid 125 mm solution

The corner turning head delivers consistent performance for shoulder and groove turning where rigidity matters. The 125 mm diameter increases the tool overhang capacity while maintaining stiffness, reducing chatter and allowing higher material removal rates. A 90° cutting angle provides straightforward geometry for right-angle operations, and the use of R390 18 indexable inserts simplifies tool maintenance: inserts are indexed or replaced without complex reclamping, cutting downtime and component handling. These characteristics translate into measurable productivity gains at the machine spindle and a predictable cycle time for batch production.

Simplified setup and coolant-assisted tool life

Integration into existing tool posts is fast thanks to the standard 40 mm shank and compact profile. The 40 mm shank and 62 mm overall length balance access and stability, keeping set-up adjustments to a minimum. Internal coolant feed is delivered directly to the cutting zone: internal coolant improves chip evacuation, reduces built-up edge and extends insert life, particularly on difficult-to-machine alloys. Fixing is straightforward with T15 Torx drive and M4x10 screws, ensuring repeatable clamp forces and secure insert retention. Compatibility with Sandvik insert geometry means familiar grades and edge forms can be used straight away, avoiding trial-and-error testing.

Designed for reliability and predictable production

A compact yet substantial mass contributes to vibration damping and positional stability during heavy cuts; the tool head’s balance and 3.558 kg mass support smoother cuts under load. With 8 cutting edges available from the installed inserts, maintenance intervals are extended and tool costs per part are reduced. The overall result is precision and repeatability across runs, making the holder suitable for serial turning applications and mixed-production shops that require consistent surface finish and dimensional control. The robust construction also supports quick index changes and straightforward tool reconditioning.
