Boring bar for finish machining — Teknik Makina THKB146TM, Ø65 mm, CCMT 09T3

A boring bar for finish machining engineered for precision internal turning and fine surface results in production and workshop environments

Precision finish tolerance 0.01 mm Fits CCMT 09T3 indexable inserts 65 mm cutting diameter for larger bores 32 mm shank, 190 mm overall length

Accurate finishing for consistent part quality

The design delivers repeatable precision in finishing cuts, enabling tolerances down to 0.01 mm for bore machining where surface condition and roundness are critical. By limiting material removal per pass, the tool reduces induced stresses and helps preserve bore geometry; this makes it well suited to applications requiring tight dimensional control. The integrated geometry and balanced mass distribution support a stable cut, which in turn improves surface finish and reduces the need for secondary operations.

Stiffness and stability that reduce vibration and rework

A robust 32 mm shank combined with a substantial body mass promotes rigidity at the cutting edge, lowering the risk of chatter during internal turning. The tool is optimised around a central cutting diameter of 65 mm, with a maximum cutting diameter capability of 80 mm, offering flexibility across a range of medium-sized bores. Compatibility with CCMT 09T3 indexable inserts allows rapid insert changes and predictable cutting behaviour, translating into lower toolholding costs and shorter set-up times for batch production.

Practical geometry and easy integration into machining cells

With a 190 mm overall length and a 130 mm cutting length, the bar fits common turret and toolpost arrangements while providing the reach required for deeper bores. The use of standard indexable inserts simplifies procurement and inventory management; spare inserts can be stocked without bespoke grinding or reconditioning. The construction balances reach with stiffness to maintain cutting performance without excessive overhang. For process planning, the tool allows straightforward parameter selection based on standard insert grades and cutting data.

Production-oriented benefits and workshop support

Specifying a tool with proven insert compatibility and a focus on finish turning reduces both tooling complexity and downtime in serial production. The combination of efficient changeover, stable cutting conditions, and a standard insert format supports predictable machining cycles and cost control. Technical advisors can provide specification checks and advice on insert grades and cutting data to match individual applications in industry and trade.
