The Carmex Carbide Tiny Tool for Boring & Profiling (MPR) is a precision cutting tool designed for small profiling and boring tasks. Its compact form and specialized geometry allow you to shape intricate profiles in tight spaces, making it ideal for small parts, fixtures, and components where larger tools can’t reach.
Crafted from premium K20-grade carbide, this tiny tool delivers strong cutting performance with excellent wear resistance. Its precise geometry supports repeatable results across multiple passes, while the 4.1 mm minimum diameter, 22 mm reach, and 0.2 mm corner radius empower you to tackle detailed work with confidence.
- Ultra-compact reach for tight features: the small diameter and extended reach enable profiling and boring in confined areas, reducing the need for workpiece repositioning.
- Premium K20 carbide for durability: offers exceptional edge retention and long tool life in demanding materials, helping you complete more cycles between replacements.
- 0.2 mm corner radius for smooth profiling: delivers clean radii and accurate transitions on intricate geometries with consistent finishes.
This tool is designed to enhance your workflow on small-part projects, delivering reliable, repeatable results with fewer setup adjustments. Its durable construction and precise geometry help you achieve better finishes, reduce rework, and maintain steady throughput across production or prototyping runs.
