Accupro 12185436 5/8 Inch 4-flute Carbide Square End Mill

Product Description

The ACCUPRO 12185436 is a solid carbide square end mill designed for both roughing and finishing operations in a single tool. Built with four flutes and a 40-degree helix angle, it removes material aggressively while leaving a clean surface finish. The chipbreaker geometry reduces cutting forces and helps evacuate chips efficiently during heavy stock removal passes. Measuring 5/8 inches in diameter with a 1-1/4 inch length of cut and 3-1/2 inch overall length, this uncoated end mill fits standard 5/8 inch toolholders. It is a single-end, right-hand cut tool with right-hand flute direction, suited for CNC machining centers and manual mills.

This end mill is intended for machinists and tool-and-die professionals working with ferrous and non-ferrous metals in roughing-to-finish applications. The regular-length configuration makes it well-suited for general-purpose side milling, slotting, and profiling where extended reach is not required. The solid carbide construction provides rigidity and wear resistance across a broad range of shop environments, from job shops to production floor machining cells.

Key Features

• 4-flute design supports both roughing and finishing in a single pass
• 40-degree helix angle improves chip evacuation and reduces cutting forces
• Chipbreaker geometry lowers heat buildup during aggressive stock removal
• Solid carbide construction delivers rigidity and extended tool life
• Uncoated finish suitable for a wide range of base materials
• Right-hand cut, right-hand flute, single-end configuration

Compatibility

Designed as a direct-fit replacement for standard 5/8 inch shank toolholders used in CNC machining centers and manual milling machines requiring a regular-length, 4-flute square end mill.

Installation Notes

Install and remove end mills only with the spindle fully stopped and the machine in a locked-out, tagged-out state. Use a calibrated toolholder and confirm runout before initiating cuts. Inspect the collet or end mill holder for wear before seating the shank. Follow the machine manufacturer and shop safety guidelines for feeds, speeds, and depth of cut when using combination roughing-finishing tools.
