Description

The Carmex Carbide Tiny Tools - Back Turning Tool (MXR) is a precision cutting instrument designed for small turning applications. Built for professionals who machine compact parts, it specializes in back turning to deliver accurate, controlled finishes on the backside of workpieces. Crafted from premium-grade carbide, this MXR BMK tool combines durability, strength, and wear resistance in a compact form. With a minimum diameter of 4.1 mm and a reach of 10 mm, it’s ideal for turning small components with confidence.

  • Back Turning capability for precise backside finishing: Enables accurate, smooth surfaces on the rear of small parts, reducing follow-on finishing and rework while improving overall part quality.
  • Premium carbide for durability and wear resistance: Delivers long tool life and consistent performance in demanding turning applications, even with tougher materials.
  • Compact MXR geometry for small diameters and deep reach: The 4.1 mm minimum diameter and 10 mm reach provide access to tight features and recessed areas without sacrificing stability.

This tiny back turning tool helps streamline your workflow by enabling precise backside finishes on small components in a single setup. Its carbide construction resists wear to maintain sharp cutting edges, while the compact design supports reliable, repeatable results across batches. Whether you’re drilling into tight recesses, finishing hidden faces, or preparing small shafts, this MXR BMK tool delivers dependable performance and confident operation from setup to finished part.
