Accupro 12181465 Corner Radius End Mill 0.5in 2 Flute Carbide

Product Description

The ACCUPRO 12181465 is a solid carbide corner radius end mill designed for precision milling in a wide range of metalworking and machining applications. With a 0.5 inch mill diameter, a 1 inch length of cut, and a 0.02 inch corner radius, this tool produces smooth, radiused bottom transitions in pockets, slots, and profiling cuts while reducing stress concentrations at part corners. The single-end, center-cutting design allows plunge entry as well as conventional lateral milling. The bright uncoated finish and micrograin carbide substrate make it well suited for both ferrous and non-ferrous workpiece materials where coated tooling is not required.

This end mill is used in CNC machining centers, vertical mills, and manual milling machines across job shops, tool and die operations, aerospace component manufacturing, and general precision machining. Its 2-flute geometry provides adequate chip clearance for slotting and full-width cuts. The right-hand cutting direction and right-hand spiral flutes are standard for conventional and climb milling on CNC equipment. The 0.5 inch shank diameter fits standard ER, side-lock, and shrink-fit toolholders commonly found in production environments.

Key Features

• 0.02 inch corner radius reduces stress risers and produces smooth radiused transitions in milled pockets and profiles
• Micrograin solid carbide construction provides hardness and wear resistance superior to high-speed steel tooling
• Center-cutting end face allows direct plunge entry without pre-drilling
• 2-flute design promotes chip evacuation in slotting and full-width milling passes
• Bright uncoated finish is compatible with cutting fluids and suited for non-ferrous and ferrous materials where coating is not specified
• 40-degree helix angle improves surface finish and reduces cutting forces compared to lower-helix geometries

Compatibility

Designed as an OEM-style replacement or direct tooling selection for standard 0.5 inch shank toolholding systems used in CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the milling machine spindle is fully stopped and locked out before inserting or removing the end mill from the toolholder. Verify toolholder runout with a dial indicator before cutting to confirm the tool seats within acceptable tolerance. Follow shop-specific speeds and feeds guidelines for solid carbide end mills based on workpiece material and machine rigidity.
