Precision Engraving Tool for Machinists

The Micro 100 RNC-375-1 is a single carbide engraving tool with a 90-degree point angle and a 0.0040-inch tip width. It is designed for detailed marking and engraving work on compatible materials. The uncoated carbide construction provides hardness for consistent edge retention during operation.

Verify Holder Compatibility and Cutting Length

Before ordering, confirm that your tool holder accepts a 25/64-inch shank diameter. The length of cut is 1/2 inch, so ensure your setup accommodates this reach. Check that the machine spindle and workholding can support the required rigidity for carbide tooling at the intended speeds.

Integrates into Manual and CNC Engraving Setups

This tool fits directly into standard tooling systems using the specified shank size, freeing the operator from adapting non-standard holders. The 90-degree included angle suits V-groove and lettering applications without needing separate profiling inserts. Its uncoated surface allows for sharp engagement in softer metals and plastics where coatings may build up.
