0.0450" Kyocera .0450" 4-Flute Extended Reach Square End Carbide End Mill, AlTiN Coated, 1/8" Shank, USA Made, 1840-0450L405 K194

This .0450" 4-flute extended reach square end carbide end mill is manufactured by Kyocera from sub-micron grain solid carbide and features an AlTiN coating for improved wear resistance and heat protection in precision CNC milling applications.

This tool is part of the Kyocera Series 1840 extended reach square end mill line for deep reach milling. The square end geometry is ideal for slotting, profiling, side milling, and shoulder work where a flat-bottom cut and sharp internal corners are needed.

Its extended reach necked design helps improve access in deeper or restricted features, while the 4-flute geometry and 30° helix provide a strong balance of rigidity and finish quality. The AlTiN coating helps improve tool life in more demanding materials and higher-heat cutting conditions.

This tool is manufactured by Kyocera and made in the USA.
