Accupro 12463186 Corner Radius End Mill 0.0650 in 2 Flute

Product Description

The ACCUPRO 12463186 is a miniature corner radius end mill ground from solid micrograin carbide, designed for precision milling in tight-tolerance and small-feature applications. The 0.0650-inch cutting diameter pairs with a 0.0050-inch corner radius to produce controlled edge breaks and fine contour work without the chipping risk that plagues less rigid tooling. With a 1.4961-inch length of cut, a 30-degree right-hand spiral helix, and a bright uncoated finish, this tool is built for use in CNC machining centers and precision mills where dimensional accuracy is non-negotiable. Licensed machinists and toolroom technicians are the primary users.

This end mill suits small-part machining in industries such as medical device, aerospace, mold and die, and electronics manufacturing where miniature features and tight tolerances are standard. The centercutting geometry allows plunge entry, adding flexibility for slot milling, ramping, and pocket work. The single-end configuration and 1/8-inch shank diameter make it compatible with collet-style and precision shrink-fit toolholders commonly found on high-speed VMCs and Swiss-style lathes configured for live tooling.

Key Features

• 0.0050-inch corner radius reduces stress concentration and extends tool life on small-feature contours
• Micrograin solid carbide construction provides rigidity and wear resistance in hardened and abrasive workpiece materials
• 30-degree right-hand helix promotes efficient chip evacuation in shallow pockets and slots
• Centercutting design allows direct plunge entry without a pre-drilled start hole
• Bright uncoated finish suited for non-ferrous metals, plastics, and applications where coating adhesion to the workpiece is a concern
• Miniature series form factor with 1/8-inch shank for use in high-precision, small-bore toolholders

Compatibility

Designed as an OEM-style miniature corner radius end mill compatible with standard 1/8-inch collet and shrink-fit toolholding systems on CNC vertical machining centers and precision milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Always power down and lock out the spindle before changing tooling. Seat the 1/8-inch shank fully into the collet or toolholder to the recommended gauge length to minimize runout and avoid shank slippage under cutting loads. Inspect the cutting edge under magnification before use; carbide microchipping is not always visible to the naked eye.
