Kyocera 0.0250" (0.64mm) 4-Flute Extended Reach Square End Carbide End Mill 1/8" Shank 1840-0250.213 K143

This 0.0250" (0.64mm) 4-flute extended reach square end carbide end mill is manufactured by Kyocera from solid micro-grain carbide and is made in the USA. It features a bright uncoated finish and a compact miniature geometry for precision CNC milling applications.

The extended reach design provides additional clearance beyond the cutting length, helping improve access when machining narrow slots, small pockets, and detailed features where a standard flute length may not provide enough reach.

This tool has a 0.075" length of cut, 0.213" extended reach length, and a 1/8" shank. The 4-flute square end geometry is designed for miniature diameter end milling and is well suited for fine-detail work requiring sharp corners and flat-bottom features.

Per the manufacturer listing, this tool is intended for non-ferrous metals, non-metals, and titanium alloy applications. The center-cutting design also supports plunge entry where appropriate.
