Accupro 313700 Ball End Mill 3/4 in 2 Flute Carbide Zrn

Product Description

The ACCUPRO 313700 is a single-end ball end mill engineered for precision milling in demanding metalworking and machining applications. Built from micrograin solid carbide, it delivers the hardness and wear resistance needed for high-speed cutting in ferrous and non-ferrous materials. The 3/4 inch cutting diameter pairs with a 1 inch length of cut and a 45-degree right-hand helix for aggressive chip evacuation and reduced cutting forces. A ZrN (zirconium nitride) coating adds surface hardness and heat resistance, extending tool life in abrasive materials. Licensed machinists and CNC programmers are the primary users of this tooling.

This end mill is suited for contour milling, profiling, and finishing passes where a ball-nose geometry is required to produce radiused floors and complex 3D surfaces. It is commonly used in mold and die work, aerospace component machining, and general precision job-shop applications. The stub length profile keeps deflection low in setups where rigidity is critical. Its 3/4 inch shank diameter provides solid grip in standard end mill holders and collet chucks.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• ZrN coating improves heat resistance and extends tool life in abrasive materials
• 45-degree right-hand helix promotes efficient chip evacuation and smooth cutting action
• 2-flute geometry provides chip clearance for slotting and profiling operations
• Stub length type minimizes overhang and reduces deflection at the cutting zone
• Single-end design with right-hand cutting direction for standard CNC and manual mill setups

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool compatible with standard 3/4 inch end mill holders, collet chucks, and hydraulic toolholders used in CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and locked out before loading or changing tooling. Seat the shank to the correct insertion depth per the toolholder manufacturer's specification and torque retention screws or collet nuts with calibrated tooling wrenches. Inspect the cutting edges and coating for chips or damage before each use.
