Accupro 313429 Corner Radius End Mill 3/4 in Solid Carbide

Product Description

The ACCUPRO 313429 is a single-end corner radius end mill ground from solid carbide micrograin stock and coated with zirconium nitride (ZrN) for extended tool life in demanding milling applications. The cutter runs a 3/4 inch diameter with a 0.120 inch corner radius, a 1 inch length of cut, and a 4 inch overall length. The 2-flute, right-hand spiral geometry with a 45-degree helix angle promotes efficient chip evacuation and reduces heat buildup during aggressive passes. Centercutting capability allows plunge entry without a pre-drilled start hole, giving machinists flexibility in tool path programming.

This end mill is suited for milling operations on ferrous and non-ferrous metals where a defined corner radius is required on finished walls or floors. The ZrN coating adds surface hardness and reduces friction against workpiece materials, extending tool life compared to uncoated carbide in similar cuts. Typical applications include contouring, slotting, and profiling operations on machining centers and CNC mills in job shop and production environments. A licensed machinist or CNC operator handles installation and setup.

Key Features

• 0.120 inch corner radius produces a consistent radius blend at wall-to-floor transitions
• Solid carbide micrograin construction provides rigidity and wear resistance
• ZrN coating reduces friction and extends tool life versus uncoated carbide
• 45-degree helix angle with 2-flute spiral geometry promotes chip evacuation
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut and right-hand flute direction compatible with standard spindle rotation

Compatibility

Designed as a direct-fit replacement for standard 3/4 inch shank toolholders including ER collet chucks, Weldon-style side-lock holders, and shrink-fit holders with a 3/4 inch bore. Shank diameter tolerance is +0.0001 inch to -0.0004 inch for precise holder engagement.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the spindle drive before inserting or removing the tool from the holder. Verify holder bore condition and cleanliness before seating the shank to maintain runout tolerance. Do not exceed the tool manufacturer's recommended depth-of-cut or feed rate parameters for the workpiece material and coating type.
