Stable cutting performance for precise bores

The Boring bar for DC-- 11T3 indexable inserts is engineered for dimensional stability during internal turning. Its S32T shank and 32 mm shaft provide a stiff connection to toolholders, reducing chatter and vibration—critical for maintaining tight tolerances in finished bores. The combination of a 40 mm cutting diameter and 34 mm cutting height concentrates cutting forces into a predictable vector, which helps preserve roundness and surface finish. In practice, this translates to fewer rework cycles and more consistent first-pass yields on serial production runs.

Clear compatibility and machining behaviour explained

Designed specifically for DC-- 11T3 indexable inserts, the bar accepts established insert geometries that simplify tooling management and spare-part stocking. The right-hand cutting configuration and the modest 3° cutting angle promote controlled chip formation and directional chip flow away from the bore, reducing the risk of recutting. The use of indexable inserts means edges can be rotated or replaced quickly without regrinding the body, saving set-up time and lowering life-cycle costs. The designation K197TM identifies the exact variant for ordering and cross-referencing in tooling lists.

Practical advantages in workshop and production settings

With an overall length of 300 mm the tool offers extended reach for deeper internal operations while the 22 mm clamping width on the cutting head secures the insert assembly for repeatable set-ups. At approximately 1.864 kg, the assembly balances mass for stable cuts without imposing excessive stress on the turret or spindle. These characteristics support efficient cycle times and predictable tool-change intervals, contributing to improved throughput. The robust construction suits a range of applications from precision finishing to medium-engagement roughing where indexable insert strategies are favoured for their cost-effectiveness and rapid maintenance.

FAQ

What materials is this boring bar suited for?
The boring bar K197TM is intended for general internal turning; compatibility with specific materials depends on the chosen DC-- 11T3 insert grade rather than the bar itself.

How does the S32T shank benefit machining?
An S32T shank increases connection rigidity between the tool and holder, improving stability and reducing vibration for more accurate bores with repeatable surface finishes.

Can the cutting direction be changed?
This variant is configured for right-hand cutting; for left-hand operations, an alternative tool geometry would be required.

What does the 3° cutting angle affect in practice?
The 3° cutting angle helps to control chip flow and cutting forces, leading to improved chip evacuation and reduced cutting resistance during internal turning.

Which inserts should be ordered for this bar?
Use DC-- 11T3 indexable inserts matched to the intended material and feed parameters; the bar is mechanically compatible with that insert family.
