Sandvik Coromant 5722028 Indexable Boring Bar 20mm Rh

Product Description

The SANDVIK COROMANT 5722028 is a steel-body indexable boring bar from the CoroTurn 107 series, designed for internal turning operations on CNC lathes and turning centers. It features a 16 mm shank diameter and a 200 mm overall length, with a minimum bore diameter of 20 mm (0.7874 inches). The screw-clamping insert holding method provides secure seating under cutting loads. A neutral rake angle and -5 degree lead angle make this bar suited for general-purpose internal turning where consistent chip control and dimensional accuracy are priorities. Coolant-through capability supports tool life in demanding materials.

This boring bar is intended for right-hand cutting in internal turning applications on both CNC and manual turning equipment. It is well-suited for production environments requiring repeatable, tight-tolerance bores in metal workpieces. The multi-use designation confirms it is applicable across a range of turning scenarios. The center-to-cutting-edge dimension is 11 mm (0.4331 inches), which determines the effective reach from bar centerline to the active cutting zone. Licensed machinists, toolroom technicians, and CNC setup operators are the primary users of this toolholder style.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Ensure the machine spindle is fully stopped and all motion is locked out before installing or changing the toolholder or insert. Confirm correct shank bore fit and torque the clamping screws to the machine turret manufacturer's specification. Verify minimum bore diameter clearance before engaging the cutting pass to prevent interference with the workpiece wall.
