Accupro 12184996 Square End Mill 5/8 in 4-flute Solid Carbide

Product Description

The ACCUPRO 12184996 is a 4-flute solid carbide square end mill designed for roughing and finishing operations in a single tool. Built with an AlTiN coating and a 40-degree helix angle, it handles aggressive material removal while maintaining edge integrity on the finish pass. The chipbreaker geometry reduces cutting forces and aids chip evacuation, making it suitable for harder workpiece materials. At 5/8 inch in diameter with a 7/8 inch length of cut and 3 inch overall length, this is a stub-length tool optimized for rigidity in tight setups. Machinists and toolroom technicians working in production or job-shop environments are the primary users.

This end mill is suited for milling operations on steel, stainless, cast iron, and high-temperature alloys where a combination of stock removal and surface finish is required in one operation. The single-end, right-hand cutting and right-hand flute configuration fits standard vertical and horizontal milling machines, CNC machining centers, and manual mills with a 5/8 inch collet or end mill holder. The stub length and solid carbide construction favor setups where minimizing tool overhang is critical to part accuracy and chatter control.

Key Features

• AlTiN coating for elevated heat resistance and extended tool life in ferrous and high-temp alloy cutting
• 40-degree helix angle balances aggressive chip evacuation with smooth cutting action
• Chipbreaker geometry reduces cutting forces and improves chip control during heavy roughing passes
• 4-flute design supports both roughing and finishing in a single setup
• Stub length construction maximizes rigidity and minimizes deflection at the cutting edge
• Single-end, right-hand cut and right-hand flute for standard milling machine compatibility

Compatibility

Designed as an OEM-style replacement or direct procurement option for 5/8 inch shank end mill holders and collet chucks used in standard CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before changing tooling. Seat the shank fully into the holder to the recommended engagement depth before tightening set screws or collet nuts. Inspect the tool for chips or edge damage before each use and do not exceed the manufacturer-rated feed and speed parameters for the workpiece material.
