Accupro 313729 Ball End Mill 1 in 2 Flute Solid Carbide Zrn

Product Description

The ACCUPRO 313729 is a solid carbide ball end mill designed for high-performance milling in a wide range of ferrous and non-ferrous materials. With a 1 inch cutting diameter, a 3-1/4 inch length of cut, and a 6 inch overall length, this tool is built for deep-cavity and long-reach applications where rigidity and edge retention matter. The micrograin carbide substrate provides consistent hardness across the cutting edge, while the ZrN (zirconium nitride) coating reduces friction and extends tool life in demanding cuts. This is a single-end, 2-flute design with a right-hand cutting and right-hand flute direction.

This ball end mill is suited for mold and die work, deep-pocket profiling, and contour milling in machine shops and manufacturing environments. The long-length designation makes it appropriate for setups where standard-length tooling cannot reach the required depth. The 45 degree helix angle promotes smooth chip evacuation and reduces cutting forces during full-depth passes. It is installed and operated by machinists and CNC operators working with vertical or horizontal machining centers.

Key Features

• 1 inch ball nose diameter for accurate 3D contour and profile milling
• 3-1/4 inch length of cut supports deep-cavity and extended-reach operations
• ZrN coating reduces friction and improves wear resistance at elevated cutting temperatures
• Micrograin solid carbide substrate delivers edge stability and consistent performance
• 45 degree helix angle promotes efficient chip evacuation and lower cutting forces
• Right-hand cut and spiral flute direction; single-end configuration

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide ball end mill for CNC machining centers and manual mills accepting a 1 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down or in a safe lockout state before inserting or removing the tool. Seat the 1 inch shank fully in the tool holder and torque the collet or set screws per the tool holder manufacturer specifications. Inspect the cutting edges for chips or damage before each use.
