Sandvik Coromant 5722767 Indexable Boring Bar Left Hand

Product Description

The SANDVIK COROMANT 5722767 is an indexable boring bar designed for internal turning and boring operations on CNC lathes and machining centers. Built to T-Max P series specifications, this left-hand steel boring bar carries a minimum bore diameter of 3.248 inches and an overall length of 15.75 inches. It accepts DNMG 15 06 08 inserts secured by a wedge clamping method, delivering rigid, repeatable insert seating under heavy cutting loads. A negative rake angle of -6 degrees and a lead angle of -3 degrees make it well suited for finishing and semi-finishing passes in large-diameter bores. Coolant-through capability supports chip evacuation and tool life in deep-bore applications.

This boring bar is intended for metalworking professionals operating production lathes and turning centers where large internal diameters require precise, stable tooling. The A40V-DDUNL4 toolholder style fits 2-inch shank pockets and is appropriate for heavy-duty ferrous and non-ferrous material removal. With a center-to-cutting-edge dimension of 1.75 inches, it is configured for left-hand cutting directions. Machinists, tooling engineers, and CNC setup technicians working in job shops, aerospace, energy, and general manufacturing will find this bar a direct fit for large-bore finishing work.

Key Features

• Minimum bore diameter of 3.248 inches supports large internal-diameter applications
• Wedge insert clamping ensures secure DNMG 15 06 08 insert retention under interrupted and continuous cuts
• Coolant-through design promotes chip flushing and extended insert life in deep bores
• Negative rake geometry reduces cutting forces on hard and tough workpiece materials
• 2-inch shank diameter provides rigid interface in standard large-bore tool blocks
• Multi-use tool designation allows flexibility across compatible insert grades and geometries

Compatibility

Designed for use with DNMG 15 06 08 inserts in the SANDVIK COROMANT T-Max P series tooling system. The A40V-DDUNL4 toolholder style accepts left-hand configurations with a 2-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine fully powered down and in a safe, locked-out state before mounting. Confirm shank diameter matches the tool block or boring head bore and torque clamping hardware to the machine or toolholder manufacturer specifications. Verify coolant-through lines are clear and properly connected before resuming cutting operations. Insert handling should follow standard carbide insert safety practices to prevent chipping and personal injury.
