Accupro 12184911 Ball End Mill 1/2 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12184911 is a single-end ball end mill designed for contouring, profiling, and 3D milling operations in ferrous and non-ferrous materials. Built from micrograin solid carbide with a TiCN (titanium carbonitride) coating, this tool delivers extended wear resistance and thermal stability in demanding cutting environments. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces across the full 3-inch length of cut. With a 6-inch overall length, this is an extra-long configuration suited for reaching deep pockets and complex workpiece geometries. It is installed by machinists and CNC programmers in production and job-shop settings.

This end mill is suited for CNC milling centers and manual mills where deep cavity work, die and mold machining, or finishing passes on complex contours are required. The 1/2-inch shank diameter fits standard ER collet chucks, hydraulic holders, and shrink-fit toolholders common in most shop environments. The extra-long 6-inch OAL makes it particularly useful when standard-length tools cannot reach the full depth of a feature. Right-hand cutting and right-hand spiral flute geometry are consistent with conventional and climb milling strategies.

Key Features

• Micrograin solid carbide substrate for rigidity and edge retention at elevated cutting speeds
• TiCN coating increases surface hardness and reduces built-up edge in ferrous materials
• 40-degree helix angle improves chip evacuation and lowers radial cutting forces
• 4-flute configuration balances material removal rate with chip clearance
• Extra-long 6-inch OAL enables deep pocket and mold cavity reach
• Single-end design with right-hand cut and right-hand flute spiral

Compatibility

Designed as an OEM-style replacement and direct application tool for CNC milling operations requiring a 1/2-inch shank ball end mill with a 3-inch length of cut in an extra-long configuration.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Always power down and lock out the spindle before mounting or removing the tool. Seat the shank fully to the recommended gauge line in the toolholder to minimize runout and deflection, which is especially critical at this extended reach. Verify toolholder clamping torque specifications per the holder manufacturer before beginning a cut.
