The Carmex Carbide Tiny Tool for Boring & Profiling (MPR) is a precision cutting tool designed for small profiling and boring applications. Its compact 1 mm minimum diameter and 4 mm reach make it ideal for shaping intricate features in miniature parts and components.
Crafted from premium-grade K20 carbide, this tool combines exceptional durability with strong edge retention, delivering reliable performance even in demanding micro-profiling tasks. The small diameter enables precise, controlled cuts in tight spaces, while the longer reach lets you access deeper pockets without reworking the setup.
- Ultra-fine 1 mm diameter with 4 mm reach: Enables precise profiling and deep-pocket access in tiny parts, delivering tight control in confined workspaces.
- R0.05 tip radius for precise radii: Supports accurate corner radii and smooth finishes on small features, enhancing detail without overcutting.
- Premium K20 carbide for wear resistance: Delivers long tool life and consistent cutting performance, reducing downtime and re-shaping the workflow with fewer tool changes.
Designed for engineers, technicians, and hobbyists alike, this tiny profiling and boring tool helps you achieve consistent geometries, finish quality, and repeatable results across delicate components—from electronics housings to micro-mechanical parts. Its durable carbide edge and compact form factor reduce setup time and enable reliable, precise work in tight channels and shallow cavities, supporting faster prototypes and higher-quality final assemblies.
