Description

Introducing the Carmex Carbide Tiny Tools Back Turning Tool (MXL)—a precision solution for small turning tasks. Its specialized back-turning geometry delivers accurate, smooth surfaces on the backside of workpieces, making micro-machining cleaner and more repeatable. Made from premium-grade carbide, it combines strength, wear resistance, and long tool life. Its compact form and left-hand orientation fit tight spaces, with a 5.1 mm minimum diameter and 22 mm reach to access recessed features.

  • Back-turning geometry refined for hidden surfaces: Enables precise, consistent finishes on the backside of small workpieces, improving surface quality in tight areas.
  • Premium carbide for durability and wear resistance: Built to withstand repeated passes and maintain sharpness, reducing tool changes and rework.
  • Compact left-hand design with defined reach: 5.1 mm minimum diameter, 22 mm reach, and left-handed orientation that fits standard micro-machining setups and helps reach into tight cavities.

With this tool, you can confidently finish backside surfaces on small parts, streamline setups, and achieve consistent results across batches. The combination of a high-grade carbide core, purpose-built back-turning geometry, and compact form factor supports faster setup, longer tool life, and higher-quality finishes in micro-machining and precision turning applications.
