Description

The Carmex Carbide Tiny Tool - Grooving (MGR) is a precision small grooving tool engineered for tight spaces and fine detail work. Made from premium-grade carbide (K20), it delivers reliable performance and long edge life for challenging small-part grooves. With its compact geometry, this tool is ideal for creating accurate grooves on tiny components across a range of industries.

Designed to fit into a variety of machines and setups, the tool’s exact specifications help you plan and execute grooves with confidence. The minimum diameter is 6.1 mm, the groove width is 2 mm, and the reach is 17 mm, giving you a versatile option for delicate grooves on compact parts without compromising rigidity or control.

  • Precise micro-grooving for tight spaces: Compact geometry and a sharp carbide edge enable accurate grooves on small parts with consistent width and depth, improving part fit and function.
  • Durable K20 carbide for long tool life: Premium carbide resists wear and maintains edge sharpness, reducing tool changes and delivering repeatable cuts through demanding materials.
  • Broad compatibility for easy integration: Designed to work with a wide range of holders and machine tools, allowing straightforward adoption into existing workflows without special adapters.

This tiny grooving tool helps you streamline production and prototyping alike. By delivering clean, consistent grooves on small components, it can shorten cycle times, reduce rework, and support reliable performance across multiple projects. With its durable construction and versatile compatibility, you can trust it to perform consistently from first cut to the final pass.
