Carmex MFR4B0.75L15 Face Grooving Tool 4mm Carbide

Product Description

The CARMEX MFR4B0.75L15 is a solid carbide face grooving tool designed for internal grooving operations in small-bore applications. With a 4mm shank diameter and a 0.0300-inch groove width, this tool is built for precise, repeatable cuts in tight bore conditions starting at a minimum hole diameter of 0.2000 inches. Solid carbide construction delivers the rigidity and wear resistance required for consistent performance in both interrupted and continuous grooving cuts. Machinists and CNC operators working on precision turned components will find this tool suited to demanding tolerances in production environments.

This face grooving tool is intended for use in small-diameter internal bore applications on CNC lathes and turning centers. It is well suited for creating internal face grooves such as O-ring grooves, snap ring grooves, and relief channels in components where bore access is limited. The 4mm shank allows fitment into toolholders and boring bar systems designed for micro and small-bore work. Typical applications include precision machined parts in hydraulic, pneumatic, and fluid control assemblies where groove geometry must be held to tight dimensional standards.

Key Features

• Solid carbide construction for rigidity and extended tool life in small-bore grooving
• 4mm shank diameter for compatibility with small-bore toolholder systems
• 0.0300-inch groove width for precise, narrow face groove geometry
• Minimum hole diameter of 0.2000 inches enables access in tight bore conditions
• Maximum hole depth of 0.5900 inches (39/64 inch) accommodates a range of bore depths
• 0.0500-inch projection provides controlled cutting reach without excessive overhang

Compatibility

Designed as an OEM-style replacement and standard fitment for small-bore face grooving applications using 4mm shank toolholder systems on CNC lathes and turning centers.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC technician. Ensure the toolholder and spindle are locked out and the machine is fully stopped before mounting or removing this tool. Verify shank seating and clamping torque per the toolholder manufacturer specifications before beginning any cut. Confirm bore diameter clearance meets the 0.2000-inch minimum before engaging the cutting edge to avoid tool damage or workpiece scrapping.
