Fine Boring Tool for CCMT 09T3 Indexable Inserts — 240 mm nominal diameter, 40 mm shank — Teknik Makina

The Fine Boring Tool for CCMT 09T3 Indexable Inserts is a purpose-built finishing tool intended for precision boring and internal profiling with indexable carbide inserts.

• 240 mm nominal cutting diameter
• Compatible with CCMT 09T3 indexable inserts
• 40 mm shank diameter for rigid mounting
• 93.7 mm cutting height for extended reach

Achieve consistent finishing with large-diameter stability

The tool is designed for precision finishing operations where repeatable bore quality matters. With a 240 mm nominal cutting diameter and a geometry optimised for fine stock removal, the head delivers stable cutting conditions that reduce vibration and surface waviness. The 40 mm shank provides a secure interface with standard toolholders, improving run-out control; this results in a measurable improvement in roundness and surface finish compared with less rigid solutions. For machinists looking to maintain tight tolerances, the combination of diameter and shank rigidity translates directly into fewer rework cycles and higher first-pass yield.

Secure clamping and extended reach for versatile machining

The assembly’s 93.7 mm cutting height gives extended reach into deeper bores without compromising stiffness. Extended reach components can often introduce deflection; this tool mitigates that through a robust profile and correct centre of mass, helping to maintain cutting geometry under load. In practice, this means operators can perform finishing passes in one set-up where previously multiple tools were required. The result is reduced handling time, fewer tool changes and improved throughput on medium to large boreings.

Indexable-carbide compatibility that reduces tooling costs

Compatibility with CCMT 09T3 indexable inserts means the tool accepts a widely used, readily available carbide grade and geometry. Indexable inserts allow for rapid edge changes and the selection of grades optimised for steel, cast iron or non-ferrous materials. Because the insert pocket and seat conform to established standards, workshop inventory is simplified and tooling downtime is minimised. The pragmatic economics of indexable tooling—lower per-edge cost and straightforward regrinding policies for holders—support sustained production runs and predictable operating budgets.

Practical applications and operational advantages

Engineered for finishing operations in general engineering and toolroom environments, the boring head is suitable for internal machining tasks where surface integrity and dimensional consistency are priorities. Typical applications include bearing seats, precision housings and stepped bores. The design supports proven machining strategies such as light depth-of-cut finishing passes at controlled feeds to deliver the desired Ra values while preserving insert life. For procurement and process engineers, the combination of Teknik Makina build quality and straightforward insert replacement provides a reliable element in production tooling assortments.

FAQ

Which inserts fit this fine boring tool?
The tool accepts CCMT 09T3 indexable inserts; Tek nika Makina’s THB112TM is furnished for this standard insert geometry.

What bore range can be finished with this tool?
The head is specified for a 240 mm nominal cutting diameter, with an indicated maximum cutting diameter of 300 mm, suitable for medium-to-large internal finishing.

How does the 40 mm shank affect machining performance?
A 40 mm shank provides a stiffer connection to the toolholder, reducing run‑out and deflection for improved surface finish and dimensional control when using the THB112TM.

Is the tool suitable for deep bores?
The 93.7 mm cutting height offers extended reach for deeper internal features; use conservative feeds and finishing passes to maintain insert life and bore quality.

Can the tool be used for different materials?
Compatibility with CCMT inserts allows selection of carbide grades tailored to steels, cast iron or non‑ferrous materials, enabling the head to be adapted to common finishing tasks.
