Accupro 12176622 Square End Mill 9/16 in 3 Flute Carbide

Product Description

The ACCUPRO 12176622 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. Built from micrograin solid carbide, this single-end tool features a 9/16 inch (0.5625 inch) mill diameter with a 3-flute spiral configuration and a 40-degree helix angle. The stub-length geometry keeps the tool rigid under load, making it well suited for applications where overhang must be minimized. Centercutting capability allows direct plunge entry into the workpiece. Right-hand cut and right-hand flute directions follow standard CNC and manual milling machine conventions. The uncoated carbide surface is ready for use as delivered. Installed by machinists and CNC operators in job shops, tool rooms, and production machining facilities.

This end mill is used in stub-length milling applications on ferrous and non-ferrous materials where a rigid setup and accurate wall geometry are required. The 7/8 inch (0.8750 inch) length of cut and 3-inch overall length make it appropriate for shallow-to-moderate pocket milling, slotting, and profile work on vertical machining centers, CNC mills, and manual knee mills. The 9/16 inch shank diameter mates directly to standard collets and end mill holders of the same bore size.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• 3-flute spiral design with 40-degree helix angle for efficient chip evacuation
• Centercutting geometry enables direct plunge milling without pre-drilling
• Stub-length classification maximizes rigidity and reduces deflection
• Right-hand cut and right-hand flute for standard spindle rotation
• Uncoated finish — suitable for use as-is or for subsequent coating if desired

Compatibility

Designed as an OEM-style solid carbide square end mill fitting standard 9/16 inch bore collets and end mill holders used on CNC and manual vertical milling machines.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the collet or end mill holder bore matches the 9/16 inch shank diameter and that the shank is fully seated and torqued per the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use and replace the tool if edge integrity is compromised.
