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.

Questions about this item
How often will the uncoated carbide flutes on the GEM-500-4 need resharpening?
Uncoated carbide wears faster than coated versions; monitor flank wear and send the tool for professional resharpening once cutting edges dull or chipping appears.
What limits continuous cutting with the 1 in length of cut on this 0.5 in end mill?
The 1 in flute length restricts maximum axial depth per pass; exceeding it causes deflection and rapid edge breakdown.
How much heat builds up in the 1/2 in shank during all-day milling?
Uncoated carbide runs hotter than coated tools; use flood coolant or air blast to keep the 1/2 in shank temperature manageable during extended cuts.
