Frequently Asked Questions

What is the MICRO 100 Runner Cutter used for?

The MICRO 100 Runner Cutter is a carbide end mill designed for precision machining of runner systems in injection molds and die-cast tooling. Its 2-flute, 20° helix, and 3/64" radius enable efficient chip evacuation and smooth finishing in hardened steels and non-ferrous materials.

What are the specifications of the MICRO 100 Runner Cutter MRT-187-046?

The MICRO 100 MRT-187-046 is a solid carbide runner cutter with 2 flutes, a 20° helix angle, 3/64" corner radius, 0.308" flute length, and 2" overall length. It is designed for high-speed machining of mold runner channels and requires rigid toolholding for optimal performance.

Where to buy MICRO 100 Runner Cutters worldwide?
