Boring tool for fine finishing THKB140TM by Teknik Makina — 50 mm nominal diameter, 0.01 mm finish accuracy

The Boring tool for fine finishing THKB140TM is an internal boring bar engineered for precision finishing in CNC turning applications, delivering stable performance for batch and single-part production.

• Fine finishing capability to 0.01 mm
• Compatible with CCMT 09T3 inserts
• Shank Ø 32 mm for rigid clamping
• Max cutting diameter 65 mm

Keep tolerances tight with reliable fine finishing

The THKB140TM is designed to produce consistent part quality by enabling finish passes with a nominal repeatability down to 0.01 mm. This level of accuracy is achieved through a balanced combination of a rigid tool body and a long cutting reach, which together reduce deflection during light cuts. Where small surface deviations matter, the controlled geometry of the boring bar ensures that finishing cuts remove just the right amount of material, so inspection intervals are reduced and downstream processes remain predictable. The result is fewer reworks and a more efficient production flow.

Stable clamping that cuts chatter and extends tool life

A robust shank with a diameter of Ø 32 mm and an overall length of 190 mm provides the axial and radial stiffness required for vibration‑free machining when finishing internal bores. With a cutting length of 130 mm and a maximal cutting diameter of 65 mm, the tool maintains a secure interface with the machine spindle or tool post, which keeps cutting forces steady and minimises micro‑movement. Reduced vibration not only improves surface finish but also prolongs the service life of both inserts and holder, supporting longer uninterrupted production runs.

Fast set-up through standard insert compatibility

The holder is prepared for CCMT 09T3 indexable inserts, a widespread carbide grade and geometry in finishing applications. Using standard CCMT 09T3 inserts means tool changes and re‑grinds are quicker, tooling inventory is easier to manage and downtime is minimised. The insert pocket and clamping system are designed so that insert seating is positive and repeatable; consequently, interchangeability between identical holders is straightforward and set-ups can be standardised across a shop floor.

Integrates smoothly into workshop routines and production planning

With a nominal diameter of 50 mm, a weight of 2.135 kg and compact overall dimensions, this boring bar is suitable for integration into conventional lathe and CNC turning cells without significant fixturing changes. The design supports fine finishing operations where surface quality and dimension control are priorities, and the combination of length and stiffness is optimised to keep cutting forces predictable. Metav’s supply chain and quality screening in Emmerich provide traceable sourcing and consistent availability, which supports reliable scheduling for medium and long production runs.

FAQ

What insert type does the tool use?
The THKB140TM accepts CCMT 09T3 indexable inserts; this allows for fast replacement and common insert inventory across finishing tooling.

What level of finishing accuracy is achievable?
The boring bar is specified for fine finishing with a repeatability target of 0.01 mm, suitable for tight tolerance internal bores.

What are the maximum and nominal diameters for use?
Maximum cutting diameter is 65 mm while the nominal holder diameter is 50 mm, providing a balance of reach and stiffness.

What are the key dimensions that affect setup?
Relevant dimensions are overall length 190 mm, cutting length 130 mm and shank diameter 32 mm, which determine clamping and overhang requirements.

Is the tool suitable for series production?
Yes — the combination of standard insert compatibility and a rigid shank design makes the holder appropriate for repeated finishing operations in production environments.
