Greater process stability through insert compatibility

This boring tool is engineered to accept standard 16–22ER indexable inserts, enabling fast regrinding cycles and keeping machine uptime high. The ER22 clamping compatibility ensures a secure fit in common toolholders and collets, which reduces micro-movement at the cutting edge. By matching a standard insert form to a robust holder geometry, the tool lowers vibration and produces more consistent surface finishes — a clear efficiency gain for production environments where repeatability and short setup times matter. The left-hand orientation permits machining strategies that require inverted cutting directions without modifying the machine or programme.

Rigidity and reach for repeatable internal turning

A solid 25 mm shank paired with a 200 mm overall length gives a balance between reach and stiffness, while the 30 mm body diameter contributes to radial stability during internal cuts. The specified cutting height of 45 mm accommodates typical insert seating and clearance demands, and the measured weight of 0.764 kg supports predictable tool dynamics. Together, these dimensional attributes translate into reduced chatter and better tool life, which benefits cycle-time predictability and lowers scrap rates in workshop and small-series production.

Easy integration into existing setups and secure identification

Labeled with the ISO designation SIL S25R, this holder simplifies inventory management and ordering. The modular nature of the design means the bar readily integrates into ER22 clamping systems and is intended specifically for 22 ER insert formats, streamlining procurement and stocking decisions. For engineers and buyers this reduces the need for bespoke holders, enabling faster tool changes and consistent cutting results across different machines. The combination of standard dimensions and a clear ISO code supports traceability and rapid replacement when tool wear requires intervention.

FAQ

Which insert sizes are compatible with this boring bar?
The boring bar is designed for 16–22ER indexable inserts, specified for 22 ER seating; the SIL S25R designation confirms compatibility.

What clamping system is required to mount the tool?
Mounting is achieved via an ER22 clamping interface; the shank and holder geometry are matched to ER22 toolholders.

Is the cutting direction left- or right-handed?
This model is specified for left-hand cutting direction, suitable when the machining programme or toolpath requires inverted orientation.

What are the key dimensions to check for machine setup?
Key values are a 25 mm shank, 30 mm body diameter, 200 mm overall length and a 45 mm cutting height, which inform reach and clearance planning.

How is the product identified for reordering or stock?
Identification is by ISO designation SIL S25R and SKU K334TM, both of which simplify replacement and inventory control.
