Description
The Carmex Carbide Tiny Tools - Small Back Turning Tool (MXL) is a precision carbide cutting tool designed for back turning on small workpieces. Built for machinists, engineers, technicians, and hobbyists, it delivers clean backside surfaces with consistent diameter control. Its compact form fits tight turning envelopes, making it ideal for turning small parts with high precision.
Engineered for reliability, this tool uses premium-grade carbide for excellent wear resistance and long tool life. The left-hand geometry supports predictable cutting in specific machine setups, while the 4.1 mm minimum diameter and 10 mm reach provide access to hard-to-reach surfaces without compromising rigidity.
- Back turning precision for backside surfaces: Achieve accurate, consistent finishes on the hidden faces of small parts, reducing secondary finishing.
- Durable carbide construction: Premium-grade carbide delivers long tool life, sharpness retention, and wear resistance for challenging materials.
- Compact left-hand geometry (4.1 mm min diameter, 10 mm reach): Specifically sized for tight turning spaces, allowing access to small features without sacrificing rigidity.
This tool helps streamline small-part turning workflows, minimize tool changes, and deliver repeatable surface quality. The robust carbide edge resists wear, supporting consistent performance across batches. The compact form and left-hand geometry reduce setup time and increase first-pass success on backside finishing, improving overall productivity and reducing rework.
