Product Description

The LS-CT-1316 3/8" 3-Flute Ball End Mill is designed for precision CNC milling of aluminum and other non-ferrous materials. Featuring a slick DLC coating 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 DLC (diamond-like carbon) coating gives the flutes a hard, slick surface that resists built-up edge, so aluminum chips release cleanly and the tool lasts longer than an uncoated end mill.

With a 3/8" cutting diameter, 1" length of cut, and 2-1/2" overall length, this mid-size 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-1316 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.

  • DLC coating resists built-up edge in aluminum.

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

  • 3/8" diameter for faster material removal and larger pockets.

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