Accupro 12184658 Ball End Mill 0.4063 in 4 Flute Carbide

Product Description

The ACCUPRO 12184658 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.4063 inch cutting diameter and a 1 inch length of cut, this tool handles contoured surfaces, slots, and complex 3D profiles in CNC machining centers. The 4-flute configuration and 40-degree helix angle promote efficient chip evacuation and smooth finishes at higher feed rates. Manufactured from micrograin carbide, the tool offers the rigidity and edge retention needed for demanding cuts. It arrives uncoated and ready for use as a single-end tool with a right-hand cutting direction and right-hand spiral flutes.

This end mill is suited for use in vertical and horizontal machining centers running production or prototype work on steel, aluminum, and similar workpiece materials. The 7/16 inch shank diameter fits standard ER collet chucks and end mill holders commonly found in job shops and manufacturing facilities. With no extended reach and no chipbreaker geometry, this tool is optimized for direct, stable engagement in shallow-to-moderate depth applications where tight tolerances are required.

Key Features

• Solid micrograin carbide construction for edge retention and rigidity
• 0.4063 inch ball end diameter for contoured and 3D profiling work
• 4 flutes with 40-degree helix angle for efficient chip flow and surface finish
• Right-hand cutting and right-hand spiral flute direction
• Uncoated finish suitable for use with cutting fluids or dry on appropriate materials
• Single-end design with 2.75 inch overall length for compact tool projection

Compatibility

Designed as a direct-fit replacement or standard tooling option for CNC machining centers and manual mills accepting a 7/16 inch shank in ER collet chucks, end mill holders, or shrink-fit toolholders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Set tool length offset in the machine controller before cutting. Verify collet or holder bore size matches the 7/16 inch shank diameter and that the tool is clamped to the appropriate insertion depth per the toolholder manufacturer guidelines.
