Seco 00041126 Indexable Boring Bar 1.75in Right Hand

Product Description

The SECO 00041126 is a right-hand A-MVPN indexable boring bar designed for internal turning operations on CNC lathes and machining centers. It accepts VNMG 332 inserts held in place by a pin-and-clamp system, delivering consistent negative-rake cutting geometry with a -5-degree rake angle and a 95-degree lead angle. The shank measures 1.25 inches in diameter and the bar has a 14-inch overall length, providing substantial reach for deep-bore applications. Through-coolant capability delivers cutting fluid directly to the insert tip, supporting extended tool life and chip evacuation in tight bore profiles. It is installed by machinists and CNC tooling specialists in production turning environments.

This boring bar is suited for single-point internal turning on machined components requiring a minimum bore diameter of 1.75 inches. The 95-degree lead angle and VNMG 332 insert compatibility make it well matched to straight-wall and near-shoulder boring passes. The right-hand cutting direction and negative rake geometry are standard for general-purpose ferrous and non-ferrous turning on horizontal and slant-bed CNC lathes. Through-coolant delivery benefits high-speed finishing and semi-finishing passes where heat and chip control are critical.

Key Features

• Minimum bore diameter of 1.75 inches for internal turning applications
• Accepts VNMG 332 inserts with pin-and-clamp holding method
• Through-coolant channel supports chip evacuation and insert life at cutting depth
• 14-inch overall length with 1.25-inch shank diameter for rigid reach into deep bores
• 95-degree lead angle with -5-degree rake angle for controlled chip formation
• Right-hand cutting direction; steel tool body construction

Compatibility

Designed for use with VNMG 332 diamond-shaped inserts with a 3/8-inch inscribed circle and 3/16-inch insert thickness, using A-MVPN insert geometry on right-hand toolholder configurations.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the CNC program is placed in feed-hold or emergency-stop before changing tooling. Secure the shank in a compatible boring bar holder or turret station to the machine manufacturer's specified clamping torque range. Verify through-coolant passages are clear and connected before resuming cutting operations.
