Product Description

The LS-CT-0314 1/4" 3-Flute Ball End Mill is designed for precision CNC milling of aluminum and other non-ferrous materials. Featuring a bright, uncoated finish and a three-flute ball-end geometry, this end mill provides smooth 3D contours and a clean surface finish.

The three-flute ball-end design cuts smooth contours and fillets while maintaining space for chip evacuation during aluminum machining. Its uncoated cutting surfaces make it well suited for non-ferrous applications where clean, consistent cutting performance is essential.

With a 1/4" cutting diameter, 3/4" length of cut, and 2-1/2" overall length, this versatile end mill is ideal for 3D contouring, surface finishing, fillets, and round-bottom slots.

Designed for use with compatible CNC milling machines, including the Langmuir Systems MR-1 CNC Gantry Mill, the LS-CT-0314 is a versatile cutting tool for machinists, fabricators, and manufacturers working with aluminum components.

Key Features:

  • Three-flute geometry for efficient aluminum cutting and chip evacuation.

  • Uncoated bright finish suited for non-ferrous machining.

  • Ball-end geometry for 3D contours, fillets, and smooth surface finishes.

  • 1/4" diameter for general-purpose machining and medium-size features.

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