Ausdrehwerkzeug THB102TM — Internal boring tool for finishing with CCMT 09T3 inserts, Ø 240–300 mm

Ausdrehwerkzeug THB102TM is an internal boring tool designed for accurate finishing operations with CCMT 09T3 indexable inserts in medium-to-large bore applications.

• Finishing accuracy 0.01 mm
• Compatible with CCMT 09T3 inserts
• Ø 240–300 mm working range
• Holder diameter 40 mm

Precise finishing that stabilises process capability

This boring tool is engineered for consistent surface quality in finishing passes. With a fine-machining tolerance of 0.01 mm, the design reduces rework and minimises downstream inspection effort. The tool geometry and clamping arrangement support stable chip control when fitted with CCMT 09T3 indexable inserts, which helps to maintain repeatable roundness and surface finish across batches. For production environments, this translates into shorter cycle variation and improved first-pass yield.

Robust construction for secure set-up and vibration damping

A 40 mm toolholder diameter provides a rigid connection to the machine spindle, lowering the risk of chatter in larger bores. The tool’s mass (approximately 7 kg) and overall length of 163.7 mm combine to give a balanced assembly for stable cutting dynamics. The sturdy build supports predictable tool life for the inserts and reduces the need for frequent re-adjustments, which is especially valuable when processing longer runs or when high reproducibility is required.

Simple assembly and reproducible clamping

Fitting and securing the cutting insert is straightforward: the clamping screw is specified as M3.5x9 and the required Torx key size is T15, ensuring a consistent torque setting during assembly. Clear mechanical specifications make tool changes faster and reduce the chance of incorrect mounting. The design focuses on practical workshop handling so that set-up times are minimised while maintaining secure insert retention, helping to keep machining throughput high.

Applications and material considerations for finishing operations

This tool is primarily intended for finishing internal bores within the Ø 240–300 mm range using CCMT 09T3 inserts. It is suited to standard turning centres and boring mills where fine surface tolerance and concentricity are important. Typical uses include final sizing of castings, turned components and rework tasks that demand a controlled surface texture. When paired with appropriate inserts and cutting parameters, the assembly supports a wide range of finishing operations without compromising form accuracy.
