Accupro 12184628 Ball End Mill 0.2969 in 4 Flute Carbide

Product Description

The ACCUPRO 12184628 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.2969-inch cutting diameter and a 0.75-inch length of cut, this tool delivers accurate profiling, contouring, and finishing passes in machining centers and CNC mills. The 4-flute geometry and 40-degree helix angle promote efficient chip evacuation and smooth surface finishes. Built from micrograin solid carbide, this end mill holds tight tolerances and resists wear under demanding cutting conditions. It ships uncoated and is configured as a single-end tool with right-hand cutting and right-hand flute direction.

This end mill is suited for job shops, tool rooms, and production machining environments where close-tolerance profiling or 3D contouring is required. The 5/16-inch shank diameter fits standard ER collets and end mill holders common to vertical machining centers and CNC routers. With a 2.5-inch overall length, it provides enough reach for typical cavity and pocket work without sacrificing rigidity. The uncoated finish makes it a practical choice for applications where re-sharpening or use with cutting fluid is preferred over coated tooling.

Key Features

• Micrograin solid carbide construction for extended tool life and dimensional stability
• 40-degree helix angle promotes smooth chip flow and reduced cutting pressure
• 4-flute design balances material removal rate with surface finish quality
• Right-hand cut and right-hand spiral for use in standard CNC spindle setups
• Mill diameter tolerance of +0.000 to -0.002 inches ensures consistent fitment and accuracy
• Single-end configuration — no extended reach, no chipbreaker, spiral flute type

Compatibility

The 5/16-inch shank diameter is compatible with standard ER collet chucks and end mill holders used in CNC vertical machining centers and manual knee mills. Verify holder bore and runout specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the spindle before loading or removing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the collet nut to the holder manufacturer's specification. Inspect the cutting edges and shank for damage before each use, and confirm runout with a dial indicator after clamping.
