Hertel 750349 Square End Mill 5/8 in 3 Flute Solid Carbide

Product Description

The HERTEL 750349 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 5/8 inch cutting diameter, 3 flutes, and a 30-degree helix angle, it delivers efficient chip evacuation and a smooth cutting action on a wide range of workpiece materials. The micrograin carbide substrate provides wear resistance and edge retention under demanding cutting conditions. A TiN coating adds surface hardness and reduces friction at the cutting edge. At 3-1/2 inches overall length with a 1-1/4 inch length of cut, this end mill suits typical vertical and horizontal milling setups handled by machinists and tool-and-die professionals.

This end mill is suited for slot milling, profiling, and peripheral milling in ferrous and non-ferrous materials. The centercutting geometry allows plunge entry directly into the workpiece, expanding its usefulness in contouring and pocket milling operations. Right-hand cut and right-hand flute direction are standard for conventional CNC machining centers and manual knee mills. The 5/8 inch shank diameter matches common collet and end mill holder sizes found in production and job-shop environments.

Key Features

• Solid micrograin carbide construction for extended tool life and edge retention
• TiN coating reduces friction and increases surface hardness at the cutting edge
• 3 flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design permits direct plunge entry into the workpiece
• Right-hand cut and right-hand spiral flute direction for standard CNC and manual mill setups
• 5/8 inch shank diameter compatible with standard collet and end mill holder tooling

Compatibility

Designed as an OEM-style replacement or direct tooling selection for milling machines using 5/8 inch bore collets or end mill holders in production machining, job-shop, and maintenance environments.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder or collet. Verify collet bore size matches the 5/8 inch shank diameter and that the tool is seated to the correct gauge length before tightening. Inspect the cutting edges for chips or damage before each use.
