Accupro 12182955 Square End Mill 9/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12182955 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. Built from micrograin carbide, this single-end tool features 4 spiral flutes with a 40-degree helix angle and right-hand cut with right-hand flute direction. The centercutting geometry allows plunge entry as well as conventional side milling. With a 0.5625 inch diameter and 0.875 inch length of cut, it is suited for finishing and light-to-moderate material removal in tight-tolerance applications. Machinists and CNC operators are the primary users of this tool.

This end mill is appropriate for use in vertical machining centers, CNC mills, and manual knee mills across production and job-shop environments. The stub length profile and consistent shank-to-cutter diameter ratio make it well-suited for operations requiring rigidity and reduced deflection in shallow-to-moderate depth cuts. Uncoated carbide is commonly selected for non-ferrous metals, plastics, and some ferrous applications where coating chemistry is not required or where regrinding is anticipated.

Key Features

• Solid micrograin carbide construction for wear resistance and edge retention
• 4-flute spiral design with 40-degree helix angle for efficient chip evacuation
• Centercutting capability allows direct plunge milling without pre-drilled entry
• Right-hand cut and right-hand flute direction for standard CNC and manual mill setups
• Stub length (3 inches OAL) provides added rigidity and reduced deflection
• Uncoated finish suitable for non-ferrous and select ferrous machining applications

Compatibility

Designed as a standard 9/16 inch shank square end mill compatible with milling chucks, collet holders, and end mill holders sized for 9/16 inch shanks on vertical and horizontal milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool is secured in a properly sized collet or end mill holder before operation. Follow machine tool manufacturer specifications for runout tolerance and pull-out force ratings when setting tool stick-out. Verify workpiece fixturing and depth-of-cut parameters before initiating the cut cycle.
