Hertel 62852314 Roughing End Mill 5/8 in 4 Flute Cobalt

Product Description

The HERTEL 62852314 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel and coated with TiAlN for heat and wear resistance, this tool handles tough ferrous and exotic alloy workpieces. It features a 5/8 inch diameter, 4-flute spiral geometry with a coarse pitch, which breaks chips efficiently and reduces cutting forces during heavy roughing passes. The 2.5 inch length of cut and 4-5/8 inch overall length suit it for standard depth roughing in vertical and horizontal milling setups. Machinists and tooling professionals specify this end mill when cycle time and stock removal rate are the priority.

This end mill is suited for roughing applications on machining centers, knee mills, and CNC vertical mills. The coarse-pitch flute design reduces chatter and heat buildup when taking deep, wide cuts in steel, stainless, and high-temperature alloys. The TiAlN coating extends tool life at elevated cutting temperatures compared to uncoated or TiN-coated tooling. Right-hand cut and right-hand flute direction are standard for conventional milling setups. This is not a center-cutting tool and is not intended for plunge operations.

Key Features

• M42 cobalt HSS construction for hardness and toughness in difficult materials
• TiAlN coating for extended tool life at high cutting temperatures
• Coarse pitch, 4-flute spiral geometry for efficient chip evacuation during roughing
• Right-hand cut and right-hand flute direction for standard milling setups
• Single-end design with 5/8 inch shank diameter matching the cutter diameter
• Not center-cutting — designed exclusively for peripheral and side milling passes

Compatibility

Designed as an OEM-style replacement or direct fitment roughing end mill for use in standard 5/8 inch end mill holders, collet chucks, and milling machine spindles accepting that shank diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the machine spindle is fully powered down and the tool is properly seated and torqued in the holder before starting the cut. Verify runout with a dial indicator after tooling changes to avoid premature wear. Do not use this tool for plunge cutting, as it is not a center-cutting end mill.
