Product Description

The LS-CT-2504 1/4" 5-Flute Finishing End Mill is designed for precision CNC milling of stainless steel, titanium, high-temperature alloys and hardened steel. Featuring a heat-resistant AlTiN coating and a five-flute, variable-index geometry, this end mill provides chatter-free finishing in tough materials.

The five-flute, variable-index design spaces the flutes unevenly to break up the harmonics that cause chatter, so it holds a clean finish in stainless steel, titanium and hardened steel. Its AlTiN (aluminum titanium nitride) coating holds up to the heat of cutting ferrous metals, protecting the cutting edge and extending tool life in steel, stainless steel and hard alloys.

With a 1/4" cutting diameter, 3/4" length of cut, and 2-1/2" overall length, this versatile end mill is ideal for finishing passes on walls and floors, profiling, and light-to-medium cuts with a fine surface finish.

Designed for use with compatible CNC milling machines, including the Langmuir Systems MR-1 CNC Gantry Mill, the LS-CT-2504 is a versatile cutting tool for machinists, fabricators, and manufacturers working with stainless, titanium and hardened steel parts.

Key Features:

  • 5-flute, variable-index geometry that reduces chatter in tough materials.

  • AlTiN coating for heat resistance and longer tool life in ferrous metals.

  • Square-end finishing geometry for flat floors and clean walls.

  • 1/4" diameter for finishing small pockets and detailed profiles.

  • Compatible with the Langmuir Systems MR-1 CNC Gantry Mill and other suitable CNC milling machines.
