Threading boring bar K327-2TM — Internal-thread holder for 12 IR indexable inserts, Ø16 mm | Teknik Makina

The threading boring bar K327-2TM is a specialised internal-thread holder engineered for reliable machining of internal threads with IR-style indexable inserts in confined bores and CNC turning centres.

• Internal coolant for improved chip evacuation
• Compatible with 12 IR indexable inserts
• Ø16 mm shank, overall length 150 mm
• Torx fastening M3.5x11 with T8 key

Precise chip control for repeatable thread quality

The holder integrates internal coolant, which directs the coolant and air through the bar to the cutting edge; this improves chip evacuation and reduces thermal load during continuous operation. By keeping the cutting zone clear, the system promotes consistent thread form and extends insert life. For workshops aiming to reduce rework and ensure repeatable results, the coolant-fed configuration is an effective measure to maintain cycle-time stability and surface integrity.

Stable clamping and secure insert fixation for reduced vibration

A rigid fastening system with a Torx M3.5x11 screw and matching T8 key secures the indexable insert reliably in the pocket, minimising micro-movement during cutting. The robust clamping reduces chatter and supports a stable cutting geometry, which directly benefits thread tolerance and surface finish. The compact overall length and engineered shank contribute to controlled overhang and improved dynamic performance on lathes and machining centres.

Compatibility designed for quick changeover and consistent performance

Optimised for 12 IR indexable inserts, the toolholder allows fast insert replacement and repeatable positioning, cutting downtime in tool-changing routines. The combination of a standard insert format and a clear clamping interface simplifies stock management and reduces the range of consumables required. For production environments where uptime and predictable tool behaviour matter, this approach delivers a measurable efficiency gain and easier process control.

Compact dimensions that suit tight bores and industrial workflows

With a Ø16 mm shank and an overall length of 150 mm, the bar is intended for applications where space is limited yet thread accuracy cannot be compromised. The geometry supports confined bores without sacrificing access to the cutting edge, making it suitable for small-to-medium internal-threading tasks in serial production. The design balances reach and stiffness, offering a practical compromise between tool access and machining stability.
