Accupro 2500247 Square End Mill 3/8 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 2500247 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin solid carbide, this stub-length tool offers a 3/8 inch cutting diameter and a 1/2 inch length of cut, making it well-suited for shallow slotting, side milling, and profiling cuts. The 60-degree helix angle promotes aggressive chip evacuation and reduces cutting forces, which is especially valuable in harder workpiece materials. With three flutes and a right-hand cutting and flute direction, this end mill is a standard choice for CNC machinists and manual mill operators working in production and toolroom environments.

This end mill is intended for use in CNC machining centers, knee mills, and similar milling equipment. The stub length design provides added rigidity, reducing deflection during cuts. The bright/uncoated finish makes it suitable for a range of ferrous and non-ferrous materials where coating compatibility or regrinding is a consideration. It is a single-end tool with centercutting capability, allowing plunge entry into workpieces. Machinists performing die work, fixture fabrication, or general-purpose contouring will find this tool appropriate for those tasks.

Key Features

• Micrograin solid carbide construction for wear resistance and edge retention
• 60-degree helix angle promotes efficient chip evacuation and reduced cutting force
• Three-flute geometry balances chip clearance with surface finish quality
• Centercutting design allows direct plunge entry into material
• Stub length configuration increases rigidity and minimizes deflection
• Bright/uncoated finish suitable for regrinding and broad material compatibility

Compatibility

Designed as an OEM-style replacement or standard tooling option for 3/8 inch collet or end mill holder setups on CNC machining centers and manual milling machines requiring a stub-length, three-flute square end mill.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle and collet or end mill holder are clean and free of debris before seating the shank. Confirm runout with a dial indicator after tooling is secured, as shank diameter tolerance is specified at +0.0001 to -0.0004 inches. Always follow machine tool manufacturer guidelines for speed and feed recommendations based on workpiece material, and verify the tool is fully retracted and the spindle is stopped before making any adjustments.
