Gewindebohrstange K327-1TM — Internal thread boring bar, 16 mm diameter, internal coolant (Teknik Makina)

The Gewindebohrstange K327-1TM is an internal thread boring bar intended for use with IR indexable inserts, providing a compact 125 mm overall length and integrated cooling for improved surface finish and tool life

• Internal coolant for controlled cutting conditions
• Fits 11 IR indexable inserts
• 16 mm diameter, 125 mm overall length
• Secured with Torx screw M2.5x5.5 and T8 key

Deliver consistent internal threads with precise insert support

The K327-1TM is engineered to support 11 IR indexable inserts, enabling consistent pitch and flank accuracy across repetitive internal-thread cycles. The 16 mm diameter shaft contributes to reduced deflection, which in turn increases repeatability and reduces rework. For operations where reproducible thread form matters, the combination of a rigid tool body and standardised insert geometry helps maintain machining tolerances throughout production runs.

Reduced heat and improved insert life thanks to internal coolant and secure clamping

Integrated internal coolant directs lubricant and coolant towards the cutting zone, which lowers cutting temperatures and improves chip evacuation. This controlled cooling extends tool life and helps achieve cleaner thread surfaces. The insert is held with a Torx screw M2.5x5.5 (requires T8 key), a familiar fastening method that offers secure clamping and straightforward replacement, shortening downtime during insert changes.

Compact design for efficient workshop integration and predictable handling

With an overall length of 125 mm and a 16 mm diameter, this boring bar occupies little space in tight bores while still delivering the necessary stiffness for internal thread generation. The tool is suitable for standard indexable-insert workflows and is simple to stock alongside other insert tooling. Specified dimensions and familiar fastening make the component easy to document in tool lists and predictable in setup times, supporting faster changeovers and consistent cycle planning.

FAQ

What insert type does this boring bar accept?
The Gewindebohrstange K327-1TM is designed for 11 IR indexable inserts, allowing straightforward replacement and consistent thread geometry.

Is the coolant internal or external?
The tool provides internal coolant, which directs fluid to the cutting zone for improved cooling and chip control during internal threading.

What are the key dimensions to consider for setup?
Key dimensions are 16 mm diameter and 125 mm overall length; these determine rigidity and reach for bore preparation and threading.

How is the insert secured in the tool?
Insert clamping is achieved with a Torx screw M2.5x5.5, tightened or released using a T8 key for secure and repeatable fastening.

Can this tool improve cycle times in serial production?
Yes. The combination of a stiff 16 mm shaft, internal coolant and indexable inserts reduces interruptions and supports consistent thread quality, helping to streamline serial internal-thread machining.
