Accupro 12181467 Corner Radius End Mill 1/2 in 2 Flute Carbide

Product Description

The ACCUPRO 12181467 is a solid carbide corner radius end mill designed for precision milling operations in metal, composite, and hard material applications. With a 1/2 inch mill diameter and a 0.0450 inch corner radius, it produces radiused bottom cuts that reduce stress concentrations at part corners. The 2-flute, right-hand spiral geometry supports chip evacuation and suits slotting, profiling, and pocketing work. At 3 inches overall length with a 1 inch length of cut, it fits standard tool holders used by machinists and tool-and-die professionals in both CNC and manual milling setups.

This end mill is suited for single-end use in general-purpose milling on CNC machining centers and knee mills. The bright/uncoated finish makes it appropriate for materials where coated tooling is not preferred, such as aluminum and certain non-ferrous metals. Centercutting capability allows for direct plunge entry. The micrograin carbide substrate supports edge retention at moderate to high cutting speeds.

Key Features

• Solid micrograin carbide construction for edge retention and rigidity
• 0.0450 inch corner radius reduces stress risers and improves part finish at floor transitions
• Centercutting design allows direct plunge milling without pre-drilling
• 2-flute right-hand spiral geometry promotes chip clearance in slotting and pocketing
• 40 degree helix angle supports smooth cutting action and reduced chatter
• Bright/uncoated finish suitable for non-ferrous and aluminum applications

Compatibility

Designed as a direct-fit replacement for standard 1/2 inch shank tool holders used in CNC and manual milling machines requiring corner radius end mill geometry.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a calibrated tool holder and torque the retention mechanism to the tool holder specification. Verify runout with a dial indicator before committing to a production cut.
