Sandvik Coromant 5726557 Grooving Tool Solid Carbide

Product Description

The SANDVIK COROMANT 5726557 is a solid carbide internal grooving tool designed for precision groove cutting in small-bore applications. With a 4 mm (3/16 inch) shank diameter and a 1 mm groove width, it is built for tight-tolerance internal grooving work on lathes and turning centers. The overall length is 38.98 mm (approximately 1.5 inches), and the tool provides a projection of 0.80 mm. Its solid carbide construction delivers the rigidity and wear resistance required for consistent, repeatable groove profiles in production and job-shop environments. Machinists and CNC turning specialists are the primary installers of this tool.

This grooving tool is suited for internal grooving operations where bore diameter constraints demand a compact, small-shank tool. The minimum hole diameter it can enter is 4.20 mm (0.122 inches), and it can reach a maximum hole depth of 20 mm (0.5 inches). Typical applications include grooving for snap ring seats, O-ring grooves, and undercuts inside bored or drilled features on small workpieces. It is used in both production turning and precision machining environments where solid carbide tooling is specified for hardened or abrasive materials.

Key Features

• Solid carbide construction for high rigidity and extended tool life
• 1 mm groove width for precise, narrow internal groove profiles
• 4 mm shank diameter fits small-bore internal grooving applications
• Maximum hole depth of 20 mm allows reach into deeper bores
• Minimum bore entry of 4.20 mm suits tight-clearance workpieces
• Overall length of 38.98 mm provides compact tool setup on CNC and manual lathes

Compatibility

Designed as an OEM-style replacement or direct-fit internal grooving tool for CNC lathes and turning centers accepting a 4 mm round shank toolholder.

Installation Notes

This tool is installed by machinists or CNC turning technicians. Ensure the machine spindle is fully stopped and all motion is locked out before changing tooling. Seat the shank securely in the toolholder to the specified clamping depth and verify tool overhang before running. Confirm bore clearance against the 4.20 mm minimum entry diameter before beginning a grooving pass to avoid tool or workpiece damage.
