Accupro 12184682 Ball End Mill 0.5 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12184682 is a single-end ball end mill designed for precision milling operations in metal, composite, and engineered materials. Built from micrograin solid carbide, it delivers the hardness and edge retention required for demanding contouring, profiling, and 3D surface work. The 0.5-inch diameter cutting head features 4 right-hand spiral flutes with a 40-degree helix angle, promoting efficient chip evacuation and a smooth finish. With a 1-inch length of cut and 3-inch overall length, this tool suits a wide range of CNC milling applications where reach and rigidity both matter. The uncoated finish makes it straightforward to regrind when needed.

This end mill is suited for use in CNC machining centers and manual knee mills where ball-nose profiling is required. Typical applications include 3D contouring, radius slotting, and finishing passes on ferrous and non-ferrous workpieces. The right-hand cutting direction is standard for conventional CNC spindle setups. The 0.5-inch shank diameter fits standard ER collets, end mill holders, and shrink-fit tooling commonly found in production and job-shop environments.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• 4 right-hand spiral flutes with 40-degree helix for efficient chip flow
• 0.5-inch ball nose diameter with tight mill diameter tolerance of +0.000 to -0.002 inches
• 1-inch length of cut suitable for moderate-depth contouring passes
• 3-inch overall length balances reach with tool rigidity
• Uncoated finish allows easy inspection and regrinding

Compatibility

Designed as a standard single-end ball end mill with a 0.5-inch shank diameter, compatible with ER collet chucks, end mill holders, and shrink-fit tooling systems that accept 1/2-inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully powered down and locked out before changing tooling. Verify collet or holder runout with a dial indicator before cutting to protect both the tool and the workpiece. Do not exceed the manufacturer-recommended depth of cut or feed rate for the workpiece material.
