Angle tool head T423-1TM – 50 mm with internal coolant for R390 18 indexable inserts by Teknik Makina

The Angle tool head T423-1TM is a compact turning and facing holder designed for use with R390 18 indexable inserts, delivering secure clamping and coolant-fed cutting for short overhang operations on production lathes.

• 50 mm compact tool head
• Internal coolant for chip control
• Fits Sandvik R390 18 inserts
• Secure Torx T15 clamping system

Enhanced rigidity and consistent cutting results

The compact 50 mm body and modest overall length of 45 mm reduce overhang for improved stiffness, which directly improves dimensional stability during turning and shoulder work. With four cutting edges, the holder allows rapid index changes to maintain productivity and reduce downtime. The 90° cutting angle makes this head particularly suited to facing and shoulder operations, where a square cutting geometry simplifies setup and programming. These characteristics contribute to predictable tool behaviour and repeatable component quality.

Coolant-fed design for longer tool life

Internal coolant channels ensure directed lubrication and chip evacuation at the cutting edge, lowering temperatures and helping to prevent built-up edge on the insert. The presence of internal coolant supports higher sustained cutting performance and can reduce thermal distortion of the workpiece. Coupled with the compact design, the coolant-fed feed promotes consistent surface finish and longer insert life, making the holder suitable for series production where process stability is essential.

Robust clamping and straightforward maintenance

The head uses a Torx T15 drive and an M4x10 Torx screw for secure insert clamping, which simplifies replacement and minimises setup time. A secure Torx T15 clamping system offers repeatable seating and tight mechanical connection to the insert seat, reducing the likelihood of movement under load. The accessible screw type and standardised fastening make routine maintenance and insert changes efficient, supporting continuous operation in busy workshops.

Application focus and workshop integration

Designed for cooperation with Sandvik R390 18 indexable inserts, the holder adapts readily to common turning tasks such as external profiling, facing and shoulder machining when fitted with the appropriate insert geometry and grade. The modest mass of 0.303 kg and the compact form support dynamic balancing and low inertial loads on small to medium-sized lathes. Manufactured by Teknik Makina, the component is intended as a reliable tool-room element that integrates into existing toolholding systems without extensive adaptation.
