K327-4TM Threading bar — internal threads with internal coolant, compatible with 16 IR inserts

K327-4TM is a purpose-built threading bar for machining internal threads with IR indexable inserts, offering integrated coolant supply and standardised mounting for predictable workshop set-ups

• Internal coolant channel
• Designed for 16 IR indexable inserts
• Ø20 mm diameter, 170 mm overall length
• Torx screw M3.5x11, T15 key

Controlled coolant for cleaner threads and longer tool life

Integrated internal coolant directs cutting fluid precisely to the cutting edge, which improves chip evacuation and reduces built-up edge formation. This targeted cooling and lubrication results in more consistent thread profiles and contributes to extended tool life by lowering cutting temperatures and minimizing friction. For operations where chip control and surface finish matter, the central coolant feed offers a clear productivity advantage over external supply alone.

Secure clamping for fast insert changes and reliable repeatability

The bar is configured for 16 IR indexable inserts and uses a Torx fixing to ensure stable clamping during threading cycles. The Torx screw M3.5x11 and the matching T15 key provide straightforward, repeatable insert replacement with minimal downtime. The TA060 clamping plate design keeps insert seating consistent, which reduces setup variation and supports tight process tolerances when producing series or mixed-batch components.

Standardised dimensions for straightforward set-up and alignment

With a Ø20 mm shank and 170 mm overall length, the holder fits common turret and toolpost layouts while offering predictable overhang characteristics. The nominal dimensions simplify toolholder selection and make programme simulation and collision checks more reliable. The included pass shim BSP10 facilitates exact axial positioning during assembly, helping maintain thread concentricity and repeatable results across multiple machines.

Practical workshop integration and maintenance tips

The design focuses on ease of use in production environments: the combination of internal coolant and standardised fixing means fewer process interruptions and easier diagnostics when troubleshooting a thread quality issue. Spare Torx screws and the TA060 plate are simple to source, and routine checks of clamping torque on the Torx fixing maintain secure seating. For rigs that require modular tooling, this bar integrates cleanly into existing indexable-insert systems and tooling inventories.

FAQ

What type of inserts are compatible with this holder?
The holder is designed for 16 IR indexable inserts, ensuring correct seat geometry and secure clamping for internal thread machining.

Does the tool provide coolant to the cutting zone?
Yes, the K327-4TM features an internal coolant channel to deliver fluid directly to the insert cutting edge.

Which Torx fixing is used for the insert clamping?
Insert clamping uses a Torx screw M3.5x11 tightened with a T15 key for secure and repeatable clamping.

What are the key mounting dimensions to check before fitting?
Key dimensions are Ø20 mm shank diameter and 170 mm overall length; the pass shim BSP10 is provided for axial positioning.

Can the clamping plate be replaced with other designs?
The bar uses a TA060 clamping plate; replacements or compatible plates should match this specification to retain correct insert seating.
