The Carmex Carbide Tiny Tool – Grooving – MGR (BMK Grade) is a precision cutting tool designed for small grooving tasks on compact parts. Crafted from premium BMK-grade carbide, it delivers a sharp, durable cutting edge with strong wear resistance to produce clean, repeatable grooves with minimal chatter. Its compact footprint makes it well-suited for engineers, machinists, hobbyists, and shops handling delicate or intricate parts.

With a minimum diameter of 5.1 mm, a groove width of 1 mm, and a reach of 15 mm, this tool reaches tight pockets and narrow features that larger grooving tools cannot access. Its compatibility with a wide range of machines and systems makes it easy to drop into existing setups and workflows without special adapters or complex adjustments.

• Compact, precise groove geometry: Enables accurate, repeatable grooves on small parts thanks to the small diameter, narrow groove width, and extended reach, reducing setup time and part handling.
• BMK-grade carbide for durability: Delivers exceptional edge retention and wear resistance for longer tool life and consistent groove dimensions across production runs.
• Versatile, machine-friendly design: Designed to fit a wide range of machines and systems, supporting easy integration and reliable performance in both low- and high-volume environments.

This tiny grooving tool helps you complete delicate grooves efficiently, with predictable results and fewer tool changes. Its durability and broad compatibility translate to fewer interruptions, improved workflow, and consistent outcomes on small-diameter applications—from prototyping to production.
