Accupro 12184935 Ball End Mill 0.3125 in 4 Flute Carbide Ticn

Product Description

The ACCUPRO 12184935 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining environments. Built with a 0.3125 inch (5/16 inch) diameter and a 1 inch length of cut, this long-series single-end tool delivers controlled material removal in profiling, contouring, and 3D surface work. The 40-degree helix angle and micrograin carbide substrate support aggressive feed rates while maintaining edge integrity. A TiCN coating adds surface hardness and lubricity, reducing heat buildup and extending tool life in ferrous and non-ferrous applications. Machinists and CNC operators working in job shops, tool rooms, and production environments are the primary users of this tooling.

This ball end mill is suited for milling slots, pockets, and contoured profiles in materials including steel, stainless steel, cast iron, and aluminum. The 4-inch overall length and long cutting reach make it a practical choice for deep-cavity work and situations where standard-length tools cannot access the feature geometry. The right-hand cutting direction and spiral flute configuration are standard for conventional CNC machining centers and manual knee mills. Single-end configuration means the tool is replaced rather than re-indexed when worn.

Key Features

• 0.3125 inch ball nose diameter for accurate radius profiling and 3D contouring
• 4-flute spiral design supports smooth chip evacuation and improved surface finish
• TiCN coating increases hardness and reduces friction for extended tool life
• 40-degree helix angle balances cutting force and material removal rate
• Micrograin solid carbide substrate for toughness and wear resistance
• Long-series 4 inch OAL provides reach for deep-cavity milling applications

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills accepting a 5/16 inch straight shank end mill.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the spindle before inserting or removing tooling. Seat the shank fully into the tool holder and torque the set screw or collet nut to the tool holder specification. Confirm runout with a dial indicator before beginning a production cut.
