Micro 100 GEM-187-4X Carbide Square End Mill
The Micro 100 GEM-187-4X is a solid carbide square end mill built for general-purpose milling. Its AlTiN coating and shock-absorbent micro-grain substrate suit machinists working across a range of materials from soft to hard.
Conventional geometry limits for high-speed roughing
The tool uses a conventional flute design rather than a variable-helix or roughing profile. This geometry limits chip evacuation at very high feed rates and reduces stability in deep-slot or heavy-profile cuts compared with specialised roughers.
Check shank diameter and holder capacity before
Verify that your collet or end-mill holder accepts the 3/16-inch shank and that the overall length clears your work envelope. Ensure the machine spindle can run the required speed range for carbide tooling in your chosen material.

Questions about this item
Should I choose the 16-flute or 100-flute version of this carbide end mill?
The tool uses a four-flute design; the numbers 16, 100 and 187 appear in the model reference GEM-187-4X and do not indicate separate flute-count options.
What does the 187 in the model code mean when the mill is in the spindle?
The 187 in GEM-187-4X corresponds to the 3/16 inch cutting diameter, giving a standard width for general-purpose milling in soft to hard materials.
Does the straight shank follow a specific taper standard that limits the holder I can use?
The straight shank fits standard collets and end-mill holders without a taper constraint, so it works with common ER, Weldon or shrink-fit tooling.
