Accupro 12463229 Corner Radius End Mill 0.08in 2 Flute

Product Description

The ACCUPRO 12463229 is a solid carbide corner radius end mill designed for precision milling of ferrous and non-ferrous materials in tight-tolerance applications. The cutter features a 0.0800-inch diameter with a 0.0150-inch corner radius, providing a controlled edge break that reduces stress concentrations in milled corners. A two-flute geometry and 30-degree right-hand spiral helix promote efficient chip evacuation in shallow-to-moderate depth cuts. The AlTiN coating adds thermal resistance and surface hardness, extending tool life in dry or semi-dry cutting conditions. This is a single-end, centercutting tool, meaning it can plunge directly into material as well as perform peripheral cuts. Machinist and toolroom professionals working on CNC mills or high-speed machining centers are the primary users.

This end mill belongs to the Miniature series, making it suited for small-feature work such as slots, pockets, and contours in die and mold work, medical components, aerospace detail parts, and precision instrument components. The 0.625-inch length of cut accommodates moderate-depth passes without excessive tool deflection. With a 1/8-inch shank diameter and 1.5-inch overall length, it fits standard collet chucks and toolholders sized for miniature tooling. Applications typically involve CNC machining centers running high RPM with light radial engagement.

Key Features

• 0.0800-inch cutting diameter with 0.0150-inch corner radius for controlled edge geometry
• AlTiN coating for elevated thermal resistance and extended tool life in dry cutting
• 30-degree right-hand helix spiral flutes for efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece material
• Micrograin solid carbide substrate for rigidity and wear resistance in precision cuts
• Single-end configuration with 0.625-inch length of cut and 1.5-inch overall length

Compatibility

Designed as an OEM-style miniature end mill for use in standard 1/8-inch collet chucks and toolholders on CNC machining centers and manual mills equipped for small-diameter tooling.

Installation Notes

Installation and tool changes must be performed with the spindle fully stopped and the machine control in a safe state. Secure the 1/8-inch shank in a collet or toolholder to the manufacturer-specified torque for that holder type. Verify runout with a dial indicator before production use, as radial runout is especially critical at small diameters. Consult machine and toolholder documentation for recommended clamping procedures; improper clamping at miniature diameters can cause tool breakage.
