4 Flute Square End Mill, 5/16 in dia, 1-1/8 in LOC, Uncoated Solid Carbide

The Titan USA TC15520 is a long-reach 4 flute solid carbide square end mill designed for milling deep features and tall-wall profiles with precision and stability. The 5/16 in cutting diameter combined with the extended 1-1/8 in length of cut gives machinists the reach needed for deep pockets, full-depth slots, and profile work in steel, aluminum, and non-ferrous alloys. Solid carbide construction minimizes tool deflection at this extended length-to-diameter ratio, ensuring consistent dimensional accuracy throughout the cut. The uncoated finish is preferred for aluminum and non-ferrous applications. Four flutes deliver improved surface finish quality and higher chip loads compared to 2-flute designs, making the TC15520 suitable for semi-finishing and finishing operations in deep features.

• Provides the reach needed for deep pockets and full-depth slots standard tools cannot access
• Solid carbide keeps deflection to a minimum at this extended length-to-diameter ratio
• Consistent accuracy maintained from the top to the bottom of tall-wall milling operations
• 4 flutes improve finish quality and chip load vs. 2-flute at this extended reach
• Uncoated finish performs best in aluminum and non-ferrous deep-feature applications
• Suited for semi-finishing and finishing passes where depth and precision are both required
