Threading Bar K327-6TM — Internal-coolant bar for inside threading with 22 IR indexable inserts (Teknik Makina)

The Threading Bar K327-6TM is a dedicated internal threading tool designed for secure insert clamping and efficient coolant delivery during internal thread machining in lathes and turret systems.

• Internal coolant for stable chip evacuation
• Suited for 22 IR indexable inserts
• 25 mm shank diameter, 200 mm overall length
• Supplied with M4x15 Torx screw (T15) and TA063 clamp

Consistent coolant flow for extended tool life

The integrated internal coolant channel ensures a continuous supply of coolant directly to the cutting zone, which lowers cutting temperatures and reduces built-up edge formation. This targeted cooling improves tool life and process stability, allowing longer uninterrupted runs and fewer insert changes. For shops aiming for repeatable internal-thread quality, the coolant-fed design reduces the risk of thermal distortion and supports consistent thread geometry on serial parts.

Fast, repeatable insert changes and secure clamping

Compatibility with 22 IR indexable inserts and the included fastening hardware — M4x15 Torx screw (drive size T15) and TA063 clamping plate — streamlines service routines. The clamping concept provides a reliable seat for each insert, reducing setup time and ensuring correct insert orientation every time. The presence of a BSP10 gauge reference assists in preset checking and alignment, so changeovers and quality checks become quicker and more reproducible on the shop floor.

Rigid dimensions for stable internal-threading performance

A 25 mm shank diameter combined with an overall length of 200 mm delivers the necessary stiffness for internal threading in small-to-medium bores, helping to minimise vibration and deflection under cut. The bar’s geometry supports accurate thread form and surface finish while offering compatibility with common turret and chuck arrangements. Supplied by Teknik Makina, the component is intended for industrial turning environments where predictable performance and mechanical robustness are required.
