4 Flute Ball End Mill, 3/16 in dia, 1-1/8 in LOC, Uncoated Solid Carbide

The Titan USA TC18512 is a long-reach 4 flute solid carbide ball end mill engineered for deep 3D contouring and detailed surface finishing in hard-to-reach features. The 3/16 in ball nose diameter with an extended 1-1/8 in length of cut provides access to deep mold cavities, tall curved walls, and sculptured surface features beyond the reach of standard-length ball end mills. Solid carbide construction is critical at this length-to-diameter ratio, ensuring the stiffness needed for accurate curved surface milling without deflection or chatter. Uncoated carbide performs best in aluminum, brass, copper, and plastics. Four flutes provide the finest possible surface finish from a long-reach ball end mill, minimizing scallop marks and reducing post-machining hand-finishing.

• Reaches deep mold cavities and tall curved walls beyond the depth of standard ball end mills
• Solid carbide prevents chatter and deflection at this challenging length-to-diameter ratio
• 4 flutes minimize scallop marks on deep curved surfaces — less post-machining polishing needed
• Accesses tight curved geometry at depth that shorter tooling physically cannot reach
• Uncoated finish ideal for deep aluminum, brass, copper, and plastic contouring applications
• Essential for mold and die makers requiring small ball nose access at extended cutting depth
