K327-3TM Internal Thread Boring Bar — 20 mm shank, internal coolant, for 16 IR inserts (Teknik Makina)

The K327-3TM is a compact internal threading tool designed for precision internal threads using IR indexable inserts, offering internal coolant for controlled chip evacuation in confined bores

• Internal coolant for efficient chip removal
• For 16 IR indexable inserts
• 20 mm shank diameter, 170 mm overall length
• Torx clamping screw M3.5x11, key T8

Faster, cleaner internal threading through built-in coolant

The combination of an integrated internal coolant channel and a rigid construction delivers measurable process advantages: consistent lubrication and chip flushing reduce tool wear and prevent built-up edge, while stable cutting conditions improve dimensional precision. Built for indexable-insert threading, the bar ensures effective chip control in blind and through bores, helping to maintain surface quality and reduce secondary cleaning operations. Where higher throughput is required, the tool body’s coolant feed supports longer uninterrupted cycles and more predictable tool-life behaviour.

Reliable clamping and repeatable set-up for workshop efficiency

Clamping is secured by a Torx M3.5x11 screw and tightened with a T8 key, offering a fast, repeatable insert change procedure that supports short set-up times. The 20 mm shank diameter and a 170 mm overall length provide a balance of accessibility and rigidity for common internal threading tasks. Compatibility with 16 IR indexable inserts simplifies inventory and stocking decisions, since standard insert geometries can be used across multiple operations. The straightforward mechanical interface reduces set-up variability and contributes directly to improved first-pass yield.

Easy integration into production and low-maintenance operation

Designed for straightforward workshop integration, the tool accepts industry-standard IR inserts and requires only simple periodic checks: insert condition, clamping torque and coolant passage clearance. The compact design minimises interference in crowded fixtures while the internal coolant reduces the need for external flushing arrangements. For procurement and long-term planning, the tool is an economical option that supports predictive maintenance strategies and reduces operator handling time, aligning with quality-focused production routines.

FAQ

What insert type does this tool accept?
The K327-3TM accepts 16 IR indexable inserts designed for internal threading operations.

Does the bar supply coolant to the cutting edge?
Yes — the tool features an internal coolant channel that delivers lubrication directly to the cutting zone to aid chip evacuation.

What are the key dimensions to check for machine compatibility?
Check the 20 mm shank diameter and 170 mm overall length to ensure proper clearance and fit-up in existing toolholders.

How is the insert secured and which fastening tools are required?
The insert is clamped with a Torx M3.5x11 screw tightened with a T8 key for reliable, repeatable clamping.
