Micro 100 30° Carbide Engraving Tool

The Micro 100 RTC-312-2 is a double-ended carbide engraving tool ground to a 30-degree included angle. It is supplied new and uncoached for machinists who need a sharp, wear-resistant point for detail marking or light engraving in metal and plastic. The 25/64 inch length of cut gives a usable reach for shallow features.

0.0040 in tip radius decides fit

The critical specification is the 0.0040 inch tip radius, which determines the finest line width and corner detail the tool can produce. If your drawing calls for a larger radius or a different included angle, this cutter will not match the required geometry. Verify the radius against your program before ordering.

No coatings or holders included

The tool ships as a bare carbide blank without coating, shank adapter or mounting hardware. Users must supply a compatible holder or collet block and apply any preferred coating in-house if the application demands it. The absence of a coating means higher friction in abrasive materials.

Questions about this item

What does the 30° angle mean for the cut profile?

The 30° included angle produces a narrow V-groove suited to fine lettering and detailed engraving work.

How does the 1/2 inch length of cut limit the tool in use?

It restricts the maximum depth of a single pass to 1/2 inch, so deeper grooves require multiple passes.

What holder size does the 25/64 in shank require?

The 25/64 inch shank fits a matching 25/64 inch collet or tool holder for secure clamping.
