TKB108TM Boring tool – for CCMT 09T3 inserts, Ø 28 mm (Teknik Makina)

The TKB108TM boring tool is a compact internal boring bar designed for precision internal turning with indexable inserts, ideal for integration into CNC lathe and boring operations.

• Solid indexable design for CCMT 09T3
• Ø 28 mm cutting capability
• 20 mm shank for high rigidity
• 105 mm effective cutting length

Precision bores with stable geometry

The TKB108TM is engineered to deliver repeatable bore accuracy by pairing a rigid tool body with standard indexable inserts. Compatibility with CCMT 09T3 inserts allows controlled cutting-edge replacement without full regrinding, reducing setup variability. The tool’s 20 mm shank and optimised mass distribution increase stiffness at the cutting edge, which helps to limit vibration and to preserve the intended bore diameter over longer runs. For manufacturers seeking predictable part-to-part consistency, this configuration translates into fewer reworked components and less inspection overhead.

More parts per shift through efficient tool life

Designed around replaceable inserts rather than solid tooling, this boring bar targets reduced cycle time and lower operating cost per part. Using indexable inserts means worn cutting edges are swapped quickly, minimising machine downtime. The 105 mm effective cutting length provides enough reach for many internal operations while the compact overall length of 155 mm keeps overhang low — a key factor in extending insert life and maintaining surface finish. The modest mass (0.376 kg) also facilitates handling and fast tool changes in high-mix environments, supporting higher throughput without compromising stability.

Straightforward fit into existing turning programmes

Integration into established CNC turning and boring workflows is straightforward: the unit accepts standard ISO-style inserts and is intended for mounting where a stable, short overhang is required. The TKB108TM boring bar simplifies tooling lists by using widely available CCMT 09T3 inserts, enabling easy sourcing and replacement. For technicians with less experience of indexable systems, the concept of an indexable insert can be summarised as a replaceable cutting tip that provides the same geometry every time it is refitted — an immediate route to consistent surface finish and dimensional control. Where special cutting data or coating recommendations are needed, Metav Werkzeuge can advise on ideal insert grades and feeds for the specific component material.

FAQ

Which insert type is compatible with this boring tool?
The TKB108TM boring tool is specified for use with CCMT 09T3 indexable inserts, which are standard ISO‑style turning tips used for internal boring and turning operations.

What are the key dimensions to check for mounting?
Important dimensions for mounting are the 20 mm shank diameter, the 105 mm effective cutting length and the overall length of 155 mm; these determine overhang and clearances in the toolpost.

What is the maximum cutting diameter achievable?
The tool data lists a maximum cutting diameter of 38 mm, while a nominal cutting diameter of 28 mm is indicated for typical setups, so the selected insert and holder geometry should be checked against the required bore size.

Is the tool suitable for high-speed internal turning?
The holder is designed for rigid mounting and indexable inserts; suitability for high-speed applications depends on the chosen insert grade and machine stability rather than the holder alone.

How does the indexable design affect workshop efficiency?
By using replaceable inserts such as CCMT 09T3, the TKB108TM reduces downtime for resharpening and simplifies inventory management, allowing faster tip replacement and consistent cutting geometry.
