Micro 100 RNC-125-1 Engraving Tool

This Micro 100 engraving tool is a single carbide cutter with a 90 degree included angle. It is supplied uncooded and uses inch dimensions. The length of cut is 3/8 in and the tip radius is .004 in. The tool weighs 0.01 units and is shipped new from stock.

For precision engraving and detailing

Machinists and engravers cutting V grooves, chamfers or decorative lines in metal or plastic will find the 90 degree geometry suitable. It is not for heavy roughing, high feed milling or applications that demand a coated substrate for extended tool life. Buyers needing different angles, radii or shank sizes must select another tool.

90 degree carbide geometry

The single specification that decides fit is the 90 degree included angle combined with the .004 in tip radius and 3/8 in length of cut. These three figures define the groove profile and reach. Verify that the workpiece material and machine rigidity match an uncoated carbide cutter of this size before ordering.

Questions about this item

How much heat or vibration does the carbide tip generate during a long engraving session?

The uncoated carbide tip runs cool because it removes material with a light .004 in cut depth, so heat buildup stays minimal even after hours of use.

What holder or machine is required to run this 3/8 in length-of-cut tool?

You need a spindle or collet that accepts a 3/8 in shank and can index the 90 degree included angle for precise engraving passes.

Will this engraver fit in the same tool changer as my older 1/4 in carbide bits?

No, the 3/8 in length of cut requires a larger tool pocket, so the older 1/4 in bits and this engraver cannot share the same changer slots.
