Micro 100 90° Carbide Engraving Tool

This Micro 100 RNC-250-14 is a single-flute engraving tool made from uncoated carbide. It features a 90-degree included angle and a 0.004-inch tip radius for detailed marking work. The 3/8-inch length of cut suits shallow profiling tasks in metal or plastic.

Shank fit and holder rigidity prevent chatter

The tool uses a standard shank that fits common ER collets and shrink-fit holders. Run-out must be kept low because carbide is brittle and will chip if the holder or spindle has excessive play. A secure, balanced clamping setup avoids the most common failure mode.

Shops cutting fine detail in ferrous

This cutter suits job shops and prototyping cells that need sharp 90-degree characters or ornamental lines. Operations requiring radiused tips, coated edges for abrasive alloys, or longer reach for deep pockets should evaluate alternative geometries.
