Accupro 12182613 Square End Mill 0.5512 in 4 Flute Carbide

Product Description

The ACCUPRO 12182613 is a solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous materials. Built from micrograin carbide, it delivers consistent edge integrity and extended tool life in demanding cutting applications. The 4-flute configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 0.5512 inches in diameter with a 1.2598-inch length of cut, this tool handles medium-depth side milling, slotting, and profiling operations. Center-cutting geometry allows plunge entry, expanding its range of use in CNC machining environments. It is used by machinists and tool-and-die professionals across job shops and production floors.

This end mill is suited for CNC vertical and horizontal machining centers where precision material removal is required. The right-hand cut and right-hand spiral flute orientation match standard spindle rotation on most CNC mills. The regular length configuration keeps the tool rigid and minimizes deflection during aggressive passes. The uncoated finish makes it a practical choice for applications where re-sharpening is anticipated or where coatings are not required for the workpiece material. No chipbreaker geometry keeps the cutting edge clean for finish and semi-finish passes.

Key Features

• Micrograin solid carbide construction for edge retention and tool life
• 40-degree helix angle promotes smooth cutting and effective chip flow
• Center-cutting design permits direct plunge entry into the workpiece
• 4-flute geometry balances chip evacuation with surface finish quality
• Right-hand cut and right-hand flute for standard CNC spindle compatibility
• Uncoated finish suitable for applications requiring re-sharpening or non-coated toolpaths

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 14.00 mm (0.5512 inch) shank diameter end mill with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Secure the shank in a collet or end mill holder rated for the shank diameter tolerance of -0.0001 to -0.0004 inches before use. Verify spindle rotation direction matches the right-hand cut orientation before engaging the workpiece. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut.
