Accupro 12185376 Ball End Mill 0.375 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12185376 is a double-end ball end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from solid carbide, it offers the rigidity and wear resistance needed for demanding CNC and manual milling applications. The tool features a 0.375-inch mill diameter, a 0.5-inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation and smooth cutting action. With four flutes and a bright, uncoated finish, this end mill is well-suited for shops that prefer to apply their own coatings or work with materials where an uncoated tool performs best. Machinists and toolroom professionals are the primary users.

This ball end mill is used in vertical and horizontal milling centers for contouring, profiling, and finishing operations where a spherical tip radius is required. The double-end configuration provides two usable cutting ends, extending tool life value per unit. A 0.375-inch shank diameter matches standard collet and end mill holder sizes common in production and job shop environments. The stub length designation and 2.5-inch overall length make it appropriate for setups where minimal tool overhang is preferred to reduce deflection.

Key Features

• Solid carbide construction for high rigidity and extended tool life in demanding milling applications
• Double-end design provides two cutting ends per tool
0.375-inch mill diameter with a 0.5-inch length of cut for controlled material removal
• 40-degree right-hand helix angle promotes chip evacuation and reduces cutting forces
• Four spiral flutes with right-hand cutting direction for standard milling operations
• Bright, uncoated finish suitable for dry cutting or user-applied coating processes
• Stub length at 2.5 inches overall for reduced overhang and improved rigidity at the spindle

Compatibility

Designed as an OEM-style replacement or direct-use tooling option for standard 3/8-inch collets and end mill holders used in CNC machining centers and manual knee mills.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine powered down. Secure the 0.375-inch shank in a clean, properly sized collet or end mill holder, torquing to the machine or toolholder manufacturer's specification. Inspect the cutting edges for chips or wear before each use. Follow shop safety protocols and applicable OSHA machining guidelines when operating milling equipment.
