Accupro 12184496 Ball End Mill 0.1875 in 3 Flute Carbide

Product Description

The ACCUPRO 12184496 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding profiling, contouring, and 3D surfacing work. The 3-flute, right-hand spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and reduces heat buildup during aggressive cuts. At 0.1875 inches in diameter with a 1-inch length of cut, this tool is well-suited for fine-detail work in tight-tolerance applications. The uncoated finish makes it straightforward to inspect for wear and compatible with cutting fluids commonly used in machining operations.

This end mill is used in CNC machining centers and manual mills for profiling, slotting, and contouring operations. The long-reach configuration, with a 4-inch overall length and 3/16-inch shank diameter, allows access to deeper pockets and contoured cavities without excessive tool stickout. It is a single-end tool, meaning the cutting geometry is on one end only. Machinists working in aerospace, mold-making, die work, or general precision job shop environments will find this diameter and flute count appropriate for semi-finish and finish passes in a variety of workpiece materials.

Key Features

• Micrograin solid carbide construction for improved edge retention and rigidity
• 3-flute right-hand spiral geometry with 40-degree helix angle for efficient chip evacuation
• Ball end profile for 3D contouring, profiling, and radius floor work
• Long-reach design at 4 inches overall length with 1-inch length of cut
• Uncoated finish suitable for use with cutting fluids and easy wear inspection
• Single-end configuration for consistent tool holding in standard collets and end mill holders

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide ball end mill for standard 3/16-inch collets, end mill holders, and tool-holding systems accepting a 3/16-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully powered down and locked before loading or changing tooling. Secure the 3/16-inch shank in a properly sized collet or end mill holder with adequate pull-out force for the intended depth of cut and feed rate. Verify runout with a dial indicator before beginning production cuts, as excessive runout on small-diameter carbide tools accelerates wear and increases the risk of tool breakage.
