Engraving Tool for Fine Detail Work

The Micro 100 RNC-500-2 is a carbide engraving tool built for precision marking on hard materials. Its double-ended, 90-degree tip and uncoated finish suit machinists and hobbyists who need clean, repeatable lines in metal or plastic. The 5/8 inch length of cut supports shallow passes without tool deflection. It arrives new and ready for use in a standard holder.

Replacing Worn or Single-Ended Cutters

This tool replaces dull single-ended engravers or coated bits that load up in soft alloys. The double-ended design doubles the usable life before regrinding, and the uncoated carbide resists built-up edge on aluminium and brass. The upgrade is worth it when cycle time matters and you want consistent groove geometry across a batch of parts. A 0.004 inch tip radius keeps corners sharp.

Straightforward Holder Mounting

Installation means clamping the shank in a compatible collet or tool holder and setting the stick-out for the 5/8 inch cutting length. The most common issue is excessive run-out from a worn collet, which chips the carbide tip on the first pass. Another frequent problem is feeding too fast for the 90-degree included angle, causing the tool to chatter and leave a serrated finish. Use light passes and verify holder concentricity.

Questions about this item

What shank diameter fits the Micro 100 RNC-500-2 engraving tool?

The tool has a 5/8 inch length of cut and a double-ended 90 degree carbide design; the shank diameter matches standard holders for this size.

How do I install the RNC-500-2 in a CNC spindle without damaging the carbide tips?

Use a collet or holder that matches the shank, tighten evenly to avoid runout, and avoid side loading the uncoated carbide edges during insertion.

When should I replace the Micro 100 engraving tool based on wear?

Replace when the 90 degree cutting edges show rounding or chipping, or when the .004 inch tip radius no longer produces clean lines in the material.
