Accupro 95168392 Corner Radius End Mill 1/2 in 5 Flute

Product Description

The ACCUPRO 95168392 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous metals. It features a 0.5000 inch diameter, a 0.0900 inch corner radius, and five flutes with a 45-degree right-hand helix for aggressive chip evacuation and smooth surface finishes. The AlTiN coating provides high heat resistance and extended tool life in demanding cutting conditions. The micrograin carbide substrate adds toughness and wear resistance at the cutting edge. This tool is used by machinists and tool-and-die professionals running CNC machining centers or manual mills where corner radii and flank geometry are critical to part tolerance.

This end mill suits production and job-shop milling applications where a center-cutting, single-end tool is required. The 1.2500 inch length of cut and 3.0000 inch overall length make it appropriate for medium-depth pocketing, contouring, and profiling operations. It is well suited for hard materials and high-speed machining where coating performance directly affects tool life and surface quality. The 0.5000 inch shank diameter fits standard ER collet chucks, side-lock holders, and shrink-fit tooling commonly used in CNC setups.

Key Features

• 0.0900 inch corner radius reduces stress concentrations and improves part surface finish at floor-to-wall transitions
• AlTiN coating delivers high oxidation resistance and hardness for dry or minimum-quantity lubrication cutting
• Five-flute design increases feed rate capability compared to standard four-flute end mills
• Micrograin solid carbide substrate provides superior edge retention in hard and abrasive materials
• Center-cutting geometry allows plunge entry without a pre-drilled pilot hole
• Right-hand cut, right-hand helix with regular length configuration for broad machine compatibility

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills using 0.5000 inch bore toolholders including ER collet chucks and shrink-fit systems. No specific machine model compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer torque and runout specifications. Ensure the shank is fully seated to the minimum clamping depth recommended by the toolholder manufacturer before securing. Verify spindle runout with a dial indicator before cutting to protect edge integrity on carbide tooling. Always confirm machine RPM and feed rate against the tool manufacturer cutting data for the workpiece material before engaging the cut.
