Carbide End Mills Developed for Micromachining Applications
Guhring’s Micro-Diver carbide end mills deliver plunging, 60º ramping, and high-performance milling at tool diameters at or below 1/8".
Cutting tool manufacturer Guhring reports that its microtool offerings, including the RF100 Micro-Driver, are an answer to the challenges imposed by the creation of small or miniature molds.
The Micro-Diver carbide end mills deliver plunging, 60º ramping, and high-performance milling at tool diameters at or below 1/8". With a focus on stability in the cut, the Micro-Diver was designed with an innovative flute form and specialized geometry for the transition from flute to neck. A symmetrical drilling geometry helps to optimize ramping and drilling operations.

Guhring’s new HIPIMS coating, called Durox, also provides the end mills with an optimized surface finish for chip evacuation and wear protection. Micro-Diver end mills are made from an ultra-fine carbide grade developed for micromachining applications.
What Guhring says it the smallest diver in the world is stocked in diameters from 1/32" to 1/8", with inch and metric sizes. Series 6808 is able to mill at depths of 2.5xD, and features 4 or 6 GuhroJet peripheral cooling ducts, depending on the diameter. Series 6809 can mill at depths of 5xD, and also features 4 or 6 GuhroJet peripheral cooling ducts, depending on the diameter.
