Accupro 12176609 Ball End Mill Set 4 Flute 6 Piece

Product Description

The ACCUPRO 12176609 is a 6-piece solid carbide ball end mill set covering six common diameters in a single package. Each cutter features 4 flutes and a double-end design, giving machinists two usable cutting ends per tool. The stub-length configuration provides added rigidity for milling contoured surfaces, 3D profiles, and radius features. Micrograin carbide construction supports harder workpiece materials and extended tool life compared to standard carbide grades. The uncoated finish makes these end mills suitable for a range of general-purpose milling applications where coating is not required or preferred.

This set is intended for use in CNC machining centers, knee mills, and manual or automated milling operations requiring ball-nose geometry. The six included diameters — 1/8 inch, 3/16 inch, 1/4 inch, 5/16 inch, 3/8 inch, and 1/2 inch — cover the most common stub-length ball end requirements in production and job-shop environments. A plastic storage case is included for organization and protection between uses. Machinists working in tool-and-die, mold making, and general part production will find this set a practical multi-diameter solution.

Key Features

Compatibility

Designed as OEM-style solid carbide ball end mills suitable for use in standard milling machine spindles and tool holders accepting the corresponding shank diameters.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Verify tool holder runout and clamping torque per the machine tool manufacturer specifications before cutting. Double-end tools should be inspected before flipping to the second end to confirm the used end shows no cracking or chipping that could affect holder integrity.
