Reliable indexable-insert performance for production drilling

The S40T STIR is designed to accept IR/ER 22 indexable inserts, providing a practical balance between cutting capacity and tool economy. Using indexable inserts reduces downtime for resharpening and keeps inventory manageable while maintaining consistent hole quality. The 45 mm cutting diameter and 60 mm cutting height allow for stable engagement in through-holes and interrupted cuts, and the right-hand configuration matches standard spindle rotations in most machining centres. This configuration translates to measurable improvements in cycle stability and fewer unscheduled tool changes, supporting higher throughput in repetitive drilling tasks.

Stiff shank design that improves hole accuracy

A solid 40 mm shank delivers rigidity where it matters: at the tool-to-spindle interface. Increased rigidity minimises deflection under load, which directly benefits positional accuracy and surface finish in bores. The 300 mm overall length gives reach without excessive overhang, reducing vibration risk in deep-hole applications. For workshops without specialist toolholders, the standard shank diameter simplifies mounting and promotes repeatable clamping values, which means fewer scrap parts and faster setup times on the shopfloor.

Compatibility and operational clarity for engineers and buyers

Compatibility with the common 22 IR insert size simplifies tooling decisions across milling and turning centres; the holder’s ISO designation S40T STIR clarifies its role in established tooling systems. Specifying a single holder type for a range of components reduces tool-change complexity and allows production planners to forecast insert consumption more accurately. The indexable-insert approach preserves cutting-edge geometry without altering the holder, so maintenance is limited to insert replacement rather than complete tool refurbishment, lowering total lifecycle effort.

Robustness and workshop suitability

With a mass of 2.831 kg, the holder indicates substantial build quality while remaining manageable for manual handling during tool changes. Its construction is optimised for frequent use in industrial environments rather than occasional hobby tasks; the rigidity and geometry balance sustained cutting forces and thermal loads to maintain consistent performance. For operations requiring dependable repeatability and simplified inventory, this indexable-insert drill bar offers a pragmatic solution that supports workflow continuity and reduces the need for multiple specialist tools.

FAQ

Which insert type fits this holder? The holder is compatible with IR/ER 22 indexable inserts; the S40T STIR accepts STI-style insert seats designed for that insert size.

What are the key dimensions to check for toolholder compatibility? Check the 45 mm cutting diameter, 40 mm shank diameter and 300 mm overall length to ensure correct clearance and clamping in the machine spindle and toolholder.

Is the shank size suitable for standard toolholders? The 40 mm shank is a common industrial size that fits many conventional toolholder systems and ensures a rigid connection for improved bore accuracy.

Can this holder be used for interrupted cuts or tough materials? The geometry and 60 mm cutting height support interrupted cuts, while indexable inserts can be selected specifically for tougher materials; insert specification should match the intended workpiece.
