Accupro 12177126 Ball End Mill 0.5 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12177126 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.5-inch diameter and a 40-degree helix angle, this single-end tool delivers smooth cutting action and efficient chip evacuation in a wide range of profiling, contouring, and finishing applications. The four-flute configuration provides a strong core and a high feed-rate capability. At 3 inches overall length with a 1-inch length of cut, the tool is suited for moderate-depth work where rigidity and surface finish both matter. Machined from micrograin carbide stock, it holds a sharp edge longer than standard carbide grades.

This end mill fits typical CNC machining center and manual milling machine setups using a 1/2-inch straight shank. It is used in job shops, tool-and-die operations, and production environments for 3D contouring, cavity milling, and radius profiling on molds, dies, and structural components. The right-hand cut and right-hand spiral flute direction are standard for conventional and climb milling on most vertical and horizontal machining centers. The uncoated finish makes it a straightforward choice for applications where a coated tool is not required or where re-sharpening is anticipated.

Key Features

• Solid micrograin carbide construction for edge retention and wear resistance
• Ball nose geometry enables 3D profiling, contouring, and radius milling
• Four-flute spiral design supports higher feed rates and improved surface finish
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Single-end configuration with 1/2-inch straight shank for standard collet and end mill holder compatibility
• Uncoated finish suitable for general-purpose milling and re-sharpening use cases

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for CNC machining centers and manual mills accepting a 1/2-inch shank end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the 1/2-inch shank in a properly sized collet or end mill holder and torque to the machine manufacturer's specification. Inspect the tool for chipping or runout before each use. Do not exceed the rated depth of cut for the tool diameter, and ensure spindle speed and feed rate are set according to the material being machined.
