Description

The Carmex Carbide Tiny Tool is a precision boring and profiling cutter engineered for small, intricate features. Designed for engineers, machinists, hobbyists, and manufacturing teams, this MPL tool delivers accurate profiling and shallow to deep bores in tight spaces with consistent results. Constructed from premium carbide, it combines strength, wear resistance, and long tool life to handle demanding micro-machining tasks.

  • Ultra-compact diameter with extended reach: 4.1 mm minimum diameter and 30 mm reach let you access tight cavities and deep pockets in small parts without repositioning the workpiece.
  • Premium carbide for durable, sharp edges: High-grade carbide maintains a keen cutting edge through repeated passes, reducing tool changes and delivering repeatable finishes over time.
  • Left-hand geometry with R0.2 nose for precise profiling: Left-handed cutting with a small nose radius provides clean, consistent profiles and smooth bore walls in tight tolerances.

Used in precise profiling and boring on miniature components, this tool supports efficient workflows by enabling accurate shapes in a single setup. Its combination of compact size, robust material, and deliberate geometry helps you achieve reliable, high-quality results with fewer passes and less rework—perfect for detailed work on small-scale parts and assemblies.
