Teknik Makina TKB134TM Boring Bar — Indexable for CCMT 09T3, Ø70 mm

The Teknik Makina TKB134TM is a heavy‑duty boring bar designed for precision internal machining in metalworking and CNC turning centres.

• Indexable inserts CCMT 09T3 compatible
• Max cutting diameter 90 mm
• Robust 40 mm shank, 290 mm overall length

Enhanced rigidity for deep, accurate internal cuts

The TKB134TM delivers increased rigidity through a substantial 40 mm shank and a carefully balanced mass, which reduces vibration during deep internal cuts. With a 220 mm cutting length and a listed 90 mm maximum cutting diameter, the toolholder maintains bore tolerances and roundness even under interrupted cuts. This mechanical stability translates into fewer reworks and predictable machining cycles on production lines, supporting higher first‑pass yield and lower tool change frequency.

Fast insert changes and consistent surface quality

Compatibility with indexable inserts in the CCMT 09T3 format offers straightforward, repeatable insert replacement and easy geometry selection for a range of turning tasks. The insert system allows for quick changeovers and cost‑effective maintenance: worn edges are replaced instead of the entire tool, reducing downtime and inventory complexity. Where surface finish is critical, the system supports stable chip control and a consistent surface finish, reducing the need for secondary operations.

Built for workshop reliability and simple integration

Constructed for day‑to‑day industrial use, the boring bar’s overall length of 290 mm and substantial mass (approx. 4.915 kg) afford the kind of stability expected in robust CNC turning operations. The combination of dimensions and build quality makes the bar suitable for retrofit into existing tool turrets and tool posts without complex adapters. Metav’s quality‑filter approach means the product arrives documented and ready for immediate use in production environments, supporting predictable lead times and dependable supply for workshop planning.
