Accupro 313203 Square End Mill 3/8 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 313203 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining applications. With a 3/8-inch cutting diameter and a 1-1/4-inch length of cut, it handles slotting, profiling, and peripheral milling in a single setup. The micrograin carbide substrate provides hardness and edge retention beyond what standard carbide grades offer. A 45-degree helix angle improves chip evacuation and reduces cutting forces, making it well suited for steels and non-ferrous alloys. The bright uncoated finish keeps it ready to run as-delivered without additional prep.

This end mill fits standard milling machines, VMCs, and CNC machining centers that accept a 3/8-inch straight shank. The long-length configuration, at 3 inches overall, gives machinists extra reach for deeper cavities and stepped features without requiring extended-reach toolholders. It is single-end, right-hand cutting, with right-hand flute direction. Centercutting capability allows plunge entry directly into the workpiece. Typical users include precision machine shops, tool-and-die operations, and production machining facilities.

Key Features

• Micrograin solid carbide construction for superior edge retention and wear resistance
• 45-degree helix angle promotes efficient chip evacuation and reduced heat buildup
• Centercutting design allows direct plunge milling without pre-drilling
• Long-length configuration at 3 inches OAL provides extended reach for deep-feature work
• Bright uncoated finish suitable for general-purpose milling across a range of materials
• Tight mill diameter tolerance of +0.000 / -0.002 inches ensures accurate finished dimensions

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard milling setups accepting a 3/8-inch straight shank with right-hand cutting direction.

Installation Notes

Installation is performed by qualified machinists. Secure the shank in a collet or end mill holder rated for the 3/8-inch shank diameter and verify runout before cutting. Ensure the spindle and workpiece are fully secured before engaging the tool. Follow machine manufacturer guidelines for spindle speed and feed rate based on workpiece material and depth of cut.
