Micro 100 GEM-500-4 Carbide End Mill 0.5 in 4FL Uncoated

Micro 100 GEM-500-4 Carbide End Mill

The Micro 100 GEM-500-4 is a solid carbide square end mill designed for general-purpose milling operations. It suits machinists and fabricators who need a reliable tool for profiling, slotting, and pocketing in a variety of materials. The uncoated finish makes it a practical choice for non-ferrous metals and plastics where coating buildup is undesirable. This tool is not intended for buyers who require specialised high-performance coatings for hardened steels or high-temperature alloys.

Uncoated Carbide Construction and Geometry

The uncoated carbide substrate provides sharp cutting edges and good wear resistance without the added friction of a coating layer. A four-flute design balances chip evacuation with core strength, allowing for smoother finishes and higher feed rates compared to two-flute tools in many applications. The straight flute geometry and centre-cutting capability enable plunging and ramping moves. This configuration does not serve users who need variable helix or variable pitch designs for aggressive chatter suppression.

Standard Shank and Cutting Dimensions

A 1/2 inch shank diameter fits directly into standard ER collets, Weldon flats, and shrink-fit holders without requiring reduction sleeves. The 1 inch length of cut and 3 inch overall length provide a rigid setup for shallow to medium-depth features. The 0.5 inch cutting diameter matches the shank size, eliminating a necked-down section and maximising rigidity. Builders needing extended reach for deep cavities or long overhangs will find this tool too short.
