Accupro 12184097 Ball End Mill 0.1575 in 2 Flute Carbide

Product Description

The ACCUPRO 12184097 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 0.1575-inch (4 mm) mill diameter and a 0.315-inch (8 mm) length of cut, this stub-length tool is built for high-accuracy profiling, contouring, and finishing passes in tight geometries. The micrograin solid carbide construction provides the rigidity and wear resistance needed for demanding cuts in ferrous and non-ferrous materials. A 40-degree helix angle promotes efficient chip evacuation while reducing cutting forces. The uncoated finish makes it suitable for use in materials where coating interaction is a concern.

This end mill is used in CNC machining centers and manual mills for die and mold work, contour milling, and fine detail profiling where a small-diameter ball nose tool is required. The stub length and 4 mm shank diameter make it well suited for close-tolerance applications with minimal overhang. It ships as a single-end tool with a right-hand cut and right-hand flute direction, standard for most vertical milling setups. The 50 mm overall length keeps deflection low during demanding passes.

Key Features

• Solid carbide micrograin construction for rigidity and long tool life
• 0.1575-inch (4 mm) ball nose diameter for fine contouring and profiling
• 40-degree helix angle promotes clean chip evacuation
• Stub length design reduces deflection in tight setups
• Right-hand cut, right-hand spiral flutes — compatible with standard CNC spindle direction
• Uncoated finish suitable for a wide range of base materials

Compatibility

Designed as a standard single-end ball nose end mill with a 4 mm straight shank, compatible with collet systems and end mill holders sized for 4 mm shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before inserting or removing tooling. Use a properly sized collet or end mill holder torqued to the tool holder manufacturer specification. Inspect the shank and collet bore for contamination or wear before clamping to avoid runout that can damage a small-diameter carbide tool.
