Drill bar S40T (40 mm) for DC-- 11T3 indexable inserts — Teknik Makina

The Drill bar S40T is a robust boring bar designed for heavy-duty machining with DC-- 11T3 indexable inserts, offering a 40 mm shank and a 300 mm overall length for industrial turning and boring applications.

• 40 mm shank for increased rigidity
• Compatible with DC-- 11T3 indexable inserts
• Overall length 300 mm for deep reach

Stable machining through optimised geometry

The bar is engineered with an S40T designation and a substantial shank diameter of 40 mm, which increases torsional stiffness and reduces vibration during cuts. This geometry leads to improved surface finish and longer insert life when compared with smaller shanks. In production environments where cycle time and repeatability matter, the combination of mass and form stability translates into fewer rejects and less rework, supporting lean manufacturing principles.

Precise insert interface for reliable cutting

Compatibility with DC-- 11T3 indexable inserts ensures a standardised and secure tool-to-insert connection. The specified cutting height of 45 mm and a clamp head width of 27 mm are matched to the insert geometry so that seating is exact and runout is minimised. The cutter assembly is secured using a Torx T15 key and M3.5x8.5 Torx screw, enabling consistent clamping torque and quick insert changes that reduce downtime.

Practical handling and installation benefits

With a right-hand cut and a cutting angle of 93°, the bar is suited to conventional turning set-ups and offers reliable chip evacuation in through-tool and overhang conditions. The overall length of 300 mm gives access to deeper bores while maintaining a conservative overhang-to-diameter ratio for stability. Handling is simplified by clear ISO designation and the compact interface, which allows the tool to be mounted and removed efficiently during production changeovers.

Reliability and operational impact in the workshop

Specified weight (approx. 1.914 kg) and the ISO-marked construction help planning for toolholders and machine capacity. The design supports sustained production runs: reduced vibration produces longer insert life, and the standardised interface reduces inventory complexity. For procurement, the SKU K135TM identifies the exact configuration and supports traceability across maintenance and reordering processes.
