K347-4TM SIR S60V boring bar — for IR27 indexable inserts, right-hand cut

A K347-4TM SIR S60V boring bar engineered for right-hand external turning and deep-reach operations with IR27 indexable inserts

• Robust 68 mm diameter shank
• 400 mm overall length for deep cuts
• Accepts 27 IR indexable inserts
• Right-hand cutting for conventional turning

Improved stability for consistent surface quality

The solid construction centred on a 68 mm diameter body and a 60 mm shank diameter increases rigidity, which reduces chatter and vibration during heavy turning. Greater stability translates directly into a better surface finish and extended tool life for the indexable cutters, meaning fewer interruptions for rework or tool changes and a more predictable production flow.

Fast insert changes and standardised fastening

Compatibility with IR27 indexable inserts and the dedicated clamping system simplifies maintenance cycles. Insert retention uses a Torx key size T20 and a Torx screw M5x18, allowing secure, repeatable seating with commonly available tools. The dedicated U plate TA065 and the ISO designation SIR S60V make the assembly straightforward on workshops accustomed to indexable systems, reducing downtime during insert replacement.

Extended reach for deep machining tasks

With a 400 mm overall length and a 75 mm cutting height, the tool is intended for deep external turning and extended-reach applications where shorter holders would require multiple setups. The right-hand cutting orientation supports conventional lathe arrangements and, when combined with the bar’s mass, promotes stable chip formation and efficient material removal—helping to increase throughput while maintaining process reliability.
