Accupro 12182259 Square End Mill 5/8 Inch 3 Flute Carbide

Product Description

The ACCUPRO 12182259 is a solid carbide square end mill designed for precision milling operations in metal, alloy, and composite materials. With a 5/8-inch cutting diameter and a 3-inch length of cut, it handles deep-pocket and slot milling where shorter tooling cannot reach. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 6 inches overall length, this is an extra-long configuration suited for extended-reach applications. Micrograin carbide construction provides the hardness and wear resistance needed in production machining environments. CNC machinists and toolroom operators are the primary users.

This end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills where an extended reach is required. Typical applications include deep cavity milling, shoulder milling, and full-slot cutting. The centercutting geometry allows plunge entry directly into the workpiece. The right-hand cut and right-hand spiral flute configuration is standard for conventional spindle rotation. The uncoated finish makes this tool a straightforward choice for shops that prefer to manage coatings separately or are working with non-ferrous materials.

Key Features

• 5/8-inch cutting diameter with mill diameter tolerance of +0.000 / -0.002 inches for consistent sizing
• 3-inch length of cut for deep-pocket and extended-reach milling
• Solid micrograin carbide construction for hardness and edge retention
• 40-degree helix angle promotes aggressive chip evacuation and reduced heat buildup
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute spiral configuration for standard CNC spindle rotation
• 6-inch overall length classified as extra long for clearance in deep setups

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC and manual milling applications requiring a 5/8-inch diameter, 5/8-inch straight shank, and extra-long reach geometry.

Installation Notes

Installation is performed by machinists and CNC tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the 5/8-inch shank in a properly sized collet or end mill holder, verifying runout with a dial indicator before production use. Follow shop-specific feeds and speeds protocols for the workpiece material; do not exceed the toolholder's rated clamping torque.
