Hertel 62852165 Roughing End Mill 1 in 5 Flute Cobalt

Product Description

The HERTEL 62852165 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a TiAlN coating, it handles high-heat cutting conditions found in tough ferrous and stainless alloys. The tool measures 1 inch in diameter with a 2-inch length of cut and a 4.25-inch overall length. Its coarse-pitch, 5-flute spiral geometry breaks chips efficiently and reduces chatter during heavy roughing passes. The 0.75-inch shank diameter provides rigid tool holding in standard end mill holders. This cutter is intended for machinists and tool-and-die professionals running manual or CNC vertical mills.

This roughing end mill is suited for roughing and semi-finishing passes on ferrous metals, alloy steels, and stainless steels in job shop and production environments. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC machining centers and manual knee mills. It is a single-end tool, so it is replaced rather than flipped when worn. The non-center-cutting design means it requires a pre-drilled or pre-bored entry point and is not suited for plunge cuts.

Key Features

• M42 cobalt steel construction for elevated heat resistance in tough alloy cuts
• TiAlN coating extends tool life in dry and high-speed machining conditions
• 5-flute coarse-pitch geometry for aggressive chip removal and reduced vibration
• Right-hand cut and right-hand spiral flute for standard CNC and manual mill setups
• Non-center-cutting design requires a pre-bored entry point
• 0.75-inch shank fits standard end mill holders and collets

Compatibility

Designed as a standard single-end roughing end mill with a 0.75-inch shank diameter, compatible with end mill holders, set-screw holders, and collet chucks sized for 0.75-inch shanks on vertical machining centers and manual knee mills.

Installation Notes

Installation is performed by qualified machinists. Secure the shank in a properly sized end mill holder or collet chuck and torque the retention mechanism per the holder manufacturer specification. Ensure the machine spindle is fully stopped and locked before tool changes. Verify runout with a dial indicator after seating to confirm proper tool hold and avoid premature wear or breakage during roughing passes.
