Carmex MGR4B1.5L10 Solid Carbide Grooving Tool

Product Description

The CARMEX MGR4B1.5L10 is a solid carbide internal grooving tool designed for precision groove cutting in small-bore applications. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for accurate, repeatable grooves in hardened or abrasive workpiece materials. The tool features a 4 mm shank diameter and cuts a groove width of 0.060 inches, making it well suited for tight-tolerance work where consistent groove geometry is critical. Machinists and toolroom professionals use this tool on CNC lathes and manual turning centers where fine detail and bore access are required.

This grooving tool is intended for internal grooving operations in small-diameter bores, with a minimum hole diameter of 0.160 inches and a maximum hole depth of 0.390 inches. It is a common choice for applications such as snap ring grooves, oil grooves, and seal grooves in precision machined components across general manufacturing, hydraulic, and aerospace part production environments. The compact overall length and controlled projection make it practical for confined bore entries.

Key Features

• Micrograin solid carbide construction for superior edge retention and wear resistance
• 4 mm shank diameter sized for small-bore toolholders and cartridge systems
• 0.060 inch groove width for precise, repeatable internal groove profiles
• 0.040 inch projection limits deflection and maintains dimensional accuracy in deep or narrow bores
• Minimum hole diameter of 0.160 inches enables access to very small internal features
• Maximum hole depth of 0.390 inches accommodates typical short-bore grooving requirements

Compatibility

Designed as an OEM-style replacement or direct-fit option for standard 4 mm shank internal grooving toolholders used in small-bore turning applications on CNC and manual lathes.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the tool turret is locked out before seating or removing the grooving tool. Secure the 4 mm shank firmly in the toolholder to the manufacturer-specified clamping method to prevent tool pullout during cutting. Verify projection length and bore clearance before engaging the workpiece to avoid tool-to-bore contact outside the intended cut zone.
