Sandvik Coromant 5733373 Indexable Boring Bar 16mm Rh

Product Description

The SANDVIK COROMANT 5733373 is a solid carbide indexable boring bar in the CoroTurn 111 series, designed for internal boring and turning operations on CNC lathes and machining centers. The bar features a 1/2-inch shank diameter and a minimum bore diameter of 16 mm (0.63 inches), with an overall length of 7.25 inches (184.15 mm). Screw clamping secures a single TPMT 1.81.51 insert, and the neutral rake geometry with 0-degree lead angle and 0-degree rake angle suits a wide range of workpiece materials. This toolholder is installed and set up by CNC machinists and toolroom technicians performing precision boring and finish-turning work.

This boring bar is suited for both boring and turning applications in a right-hand cut orientation. The F-STFC toolholder style and solid carbide construction make it appropriate for small-diameter internal operations in production and job-shop environments. The 0.35-inch center-to-cutting-edge dimension and 0.50-inch neck diameter allow access into tight bores while maintaining rigidity. Coolant-through capability is not available on this model, so external or flood coolant delivery should be planned at setup.

• Minimum bore diameter of 16 mm (0.63 inches) with screw-clamp insert retention
• Compatible with TPMT 1.81.51 inserts (inscribed circle: 0.225 inches / 5.71 mm)
• Neutral rake, 0-degree lead angle - suitable for general boring and turning
• Multi-use capability: boring and turning in a single toolholder
• Right-hand cut orientation, F-STFC toolholder style, CoroTurn 111 series

Compatibility

Designed for use with TPMT 1.81.51 indexable inserts. Fits standard 1/2-inch shank boring bar holders. Suitable for boring and turning operations as part of the Sandvik Coromant CoroTurn 111 tooling system.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before changing or indexing inserts. Secure the shank fully in the boring bar holder to the recommended clamping depth to minimize overhang and chatter. Follow the insert manufacturer's recommended torque procedure for the screw-clamp fastener using the appropriate Torx or hex key driver supplied with the toolholder system.
