The Carmex Carbide Tiny Tool for Grooving (MGR) is a compact, high‑precision carbide cutter designed specifically for small-diameter grooves on tight parts. Its slender profile and optimized geometry let you create clean, repeatable grooves in limited spaces, making it a versatile choice for engineers, machinists, and hobbyists. With a 6.1 mm diameter, a 2 mm groove width, and a 15 mm reach, this tool is built to handle delicate features while maintaining strong performance across a range of machines.

• Small-diameter access for tight grooves: The compact 6.1 mm body and 15 mm reach let you reach into confined workpieces and groove small parts without sacrificing accuracy or setup time.
• 2 mm groove width for precise features: A fixed, narrow groove width delivers consistent slot dimensions, reducing finishing passes and helping you meet tight tolerances more predictably.
• Durable carbide for reliable performance: Premium carbide provides excellent wear resistance and edge stability, extending tool life and delivering steady results across demanding materials.

This tool is compatible with a wide range of machines and systems, enabling easy integration into existing setups. By combining compact size, precise groove geometry, and durable construction, it supports efficient small-part grooving workflows, minimizes rework, and helps you achieve consistent, high-quality grooves with fewer tool changes.
