Engraving Tool 1/2 Inch Cut
The Micro 100 RNC-312-24 is a double-ended carbide engraving tool with a 1/2 inch length of cut. It is suited for machinists and fabricators who need precise marking or detailing on metal workpieces. The uncoated carbide construction provides hardness for clean lines in steel and alloys. This accessory fits compatible pneumatic or rotary holders used in shop environments.
90 Degree Included Angle
The tool features a 90 degree included angle with a 0.0040 inch tip radius for fine detail work. Carbide material maintains edge geometry during extended use without the thermal buildup common in high-speed steel alternatives. Uncoated surfaces reduce drag in softer metals while resisting chipping in interrupted cuts. No external power or cooling is required beyond the host machine.
Upgrade From Single-Point Scribes
This double-ended design replaces single-point scribes or disposable carbide inserts when bidirectional engraving is needed. The jump is worth it for operators who switch tip orientations frequently and want to reduce tool-change downtime. It does not suit applications requiring coated substrates for high-temperature alloys or abrasive non-metallics. Buyers needing larger tip radii or different included angles should verify specifications before ordering.

Questions about this item
How do I mount the 1/2 inch engraving tool in my machine and what step is often missed?
Secure the 25/64 inch shank in a matching collet and verify the 90 degree tip seats fully before tightening.
What part of the carbide tip will need attention after repeated engraving passes?
The .0040 inch radius wears gradually; plan to re-sharpen or replace the tool when edges dull.
At what point does heat become the limiting factor during a long engraving run?
Uncoated carbide transfers heat quickly, so sustained cuts raise tip temperature first and can reduce edge life.
