The Carmex Carbide Tiny Tool - Grooving - MGR is a precision cutting tool designed for micro grooving on small parts. Built from premium-grade BXC carbide, this tiny tool delivers durable performance, wear resistance, and reliable cutting in space-constrained applications. Its compact minimum diameter of 7.1 mm, 2 mm groove width, and 22 mm reach let you access recessed features without repositioning the workpiece. Compatible with a broad range of machines, it’s a versatile choice for makers and manufacturers alike.

Designed for engineers, machinists, and hobbyists who need clean, accurate grooves in miniature components, this tool excels at creating grooves on connectors, small gears, housings, and other parts where precision matters.

• Ultra-compact micro grooving geometry: Enables precise 2 mm wide grooves on parts as small as 7.1 mm in diameter, with a 22 mm reach into tight recesses, reducing the need for secondary operations.
• Premium carbide for long tool life: Crafted from robust BXC-grade carbide to resist wear, maintain sharpness, and deliver consistent groove quality over more cycles and harder materials.
• Broad machine compatibility and reliable setup: Designed to fit a wide range of CNC machines and tool holders, enabling quick installation, stable cutting, and repeatable results across jobs.

This Tiny Grooving Tool helps you streamline micro manufacturing workflows. Its precise geometry and durable carbide translate to cleaner grooves, fewer rework steps, and faster setup times. In practice, you’ll experience more consistent groove dimensions, improved seating for seals or inserts, and reduced downtime from tool changes—ultimately delivering higher quality parts with greater efficiency.
