Hertel 62913660 Roughing End Mill 1/2 in 4 Flute Cobalt

Product Description

The HERTEL 62913660 is a single-end roughing end mill designed for aggressive material removal in ferrous and non-ferrous machining applications. Built from M42 cobalt high-speed steel and coated with TiAlN for heat resistance and extended tool life, this end mill features a 1/2 inch cutting diameter, a 1 inch length of cut, and a fine-pitch, right-hand spiral flute configuration. With 4 flutes and a right-hand cutting direction, it delivers efficient chip evacuation and stable cutting performance on manual and CNC milling machines. Licensed machinists and tool-and-die professionals are the primary users.

This roughing end mill is suited for use in job shops, production facilities, and maintenance machining environments where rapid stock removal is required before finish passes. The TiAlN coating supports elevated-temperature cutting, making it appropriate for hardened steels, stainless, and other demanding materials. It is not center-cutting, so plunge entry is not recommended without a pre-drilled pilot hole or ramping strategy. The 3 inch overall length and 1/2 inch straight shank fit standard collet chucks and end mill holders common in most milling setups.

Key Features

• M42 cobalt HSS construction for toughness and heat resistance in demanding cuts
• TiAlN coating extends tool life at elevated cutting temperatures
• Fine-pitch, 4-flute spiral design promotes smooth chip flow and surface finish after roughing
• Right-hand cut and right-hand flute direction for conventional milling spindles
• 1/2 inch shank diameter fits standard collet chucks and end mill holders
• Single-end design — not center-cutting, suited for peripheral and shoulder roughing

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for milling machines accepting a 1/2 inch straight-shank end mill holder or collet chuck.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state per OSHA lockout/tagout procedures. Seat the shank fully in the collet or holder and torque the retention nut to the tool holder manufacturer's specification. Because this end mill is not center-cutting, avoid direct plunge entry; use a ramp or helical interpolation entry path. Inspect the cutting edges for wear or chipping before each use.
