Accupro 313153 Square End Mill 11/32 in 2 Flute Carbide Zrn

Product Description

The ACCUPRO 313153 is a solid carbide square end mill designed for precise material removal in milling operations. It features a 11/32 inch (0.3438 inch) cutting diameter and a 1/2 inch length of cut, with a 45-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The micrograin carbide substrate provides hardness and wear resistance suited to demanding cutting environments. A ZrN (zirconium nitride) coating adds surface hardness and reduces friction, extending tool life in ferrous and non-ferrous applications. This tool is installed and operated by machinists and tool-and-die professionals in CNC and manual milling machines.

The 313153 is a stub-length end mill with a 2-1/2 inch overall length and a 3/8 inch shank diameter, making it well-suited for tight-clearance milling operations where a shorter reach reduces deflection. Its right-hand cutting and right-hand flute direction follow standard milling conventions. The two-flute geometry provides ample chip clearance, making it a practical choice for slotting, profiling, and peripheral milling in both roughing and finishing passes on a range of workpiece materials.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• ZrN coating reduces friction and extends tool life
• 45-degree helix angle promotes efficient chip evacuation
• Center-cutting design allows plunge entry into workpiece
• Right-hand cut and right-hand spiral flute direction
• Stub length profile minimizes deflection in close-tolerance work

Compatibility

Designed as a standard square end mill with a 3/8 inch shank, compatible with any milling machine or CNC machining center collet or end mill holder sized for a 3/8 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the collet nut to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a cut.
