Accupro 12182934 Corner Radius End Mill 1/2 in 4 Flute Carbide

Product Description

The ACCUPRO 12182934 is a solid carbide corner radius end mill designed for precision milling operations in metal cutting and machining applications. It features a 1/2 inch diameter with a 0.045 inch corner radius, providing a controlled edge profile that reduces chipping and extends tool life compared to a sharp-cornered end mill. The 4-flute, right-hand spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. Weighing 0.25 pounds and left in a bright/uncoated finish, this tool is well-suited for use in CNC machining centers and manual mills where a stub-length, centercutting end mill is required.

This end mill is intended for use in machine shops, tool and die operations, and production environments where tight tolerances and repeatable corner geometry are required. The stub length of cut at 5/8 inch keeps the tool rigid and minimizes deflection during aggressive passes. The single-end, centercutting design allows plunge entry into the workpiece. Machinists and CNC operators working with ferrous and non-ferrous materials will find this tool suitable for slotting, profiling, and finishing operations.

Key Features

• Solid carbide micrograin construction for hardness and wear resistance
• 0.045 inch corner radius reduces edge chipping and improves part corner durability
• 40-degree helix angle promotes smooth chip flow and reduced cutting forces
• Centercutting geometry allows direct plunge milling
• Right-hand cut and right-hand flute spiral for standard CNC spindle compatibility
• Bright/uncoated finish suitable for a wide range of base materials

Compatibility

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

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before installing or removing the end mill from the tool holder. Use a properly sized collet or end mill holder that matches the 1/2 inch shank diameter to maintain concentricity and avoid runout. Confirm tool projection and reach are appropriate for the intended cut depth before beginning the operation.
