Accupro 12183084 Corner Radius End Mill 1/2 in 4 Flute Carbide

Product Description

The ACCUPRO 12183084 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 1/2-inch mill diameter with a 0.045-inch corner radius and a 2-inch length of cut, making it well suited for profiling, slotting, and contouring where a blended corner edge is required to reduce stress concentration. The 4-inch overall length and 40-degree helix angle support efficient chip evacuation and stable cutting performance. Micrograin carbide construction provides hardness and wear resistance for demanding cutting conditions. This is a single-end, centercutting tool with right-hand flute direction and right-hand cutting direction.

This end mill is used in CNC machining centers and manual mills across job shops, tool and die operations, and production machining environments. It is appropriate for ferrous and non-ferrous materials where a corner radius profile is needed to produce fillets or protect part edges. The bright/uncoated finish makes it a versatile choice for a broad range of materials and is commonly selected when coating compatibility with a specific workpiece material is a consideration. Licensed machinists and CNC operators are the primary users of this tooling.

Key Features

• Solid micrograin carbide construction for hardness and extended tool life
• 0.045-inch corner radius for stress-reducing fillets and blended edge profiles
• 4 flutes with a 40-degree helix angle for efficient chip evacuation
• Centercutting design allows plunge entry into the workpiece
• Bright/uncoated finish suitable for a wide range of workpiece materials
• Long-length configuration at 4 inches OAL with 2-inch length of cut for extended reach applications

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual milling machines accepting a 1/2-inch shank diameter collet or end mill holder.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the spindle is fully stopped and the machine is powered down or in a safe-stop state before changing tooling. Seat the 1/2-inch shank fully in the collet or tool holder and torque the retention mechanism per the holder manufacturer specifications. Inspect the corner radius and cutting edges for chips or wear before each use.
