Hertel E2050026 Square End Mill 13/32 in 2 Flute Cobalt

Product Description

The HERTEL E2050026 is a double-end cobalt square end mill designed for milling ferrous and difficult-to-machine alloys in industrial machining applications. Built from M42 cobalt high-speed steel, it delivers improved heat resistance and edge retention compared to standard HSS tooling. The mill measures 13/32 inch (0.4063 inch) in diameter with a 13/16 inch (0.8125 inch) length of cut and a 3-3/4 inch overall length. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. The bright, uncoated finish is suited for use with cutting fluids in general-purpose milling operations. Installed by machinists and tool-and-die professionals in manual or CNC milling equipment.

This end mill is appropriate for slot milling, peripheral milling, and profiling cuts in steel, stainless steel, and other tough materials where cobalt tooling is specified. The double-end design provides two usable cutting ends, extending tool life and reducing per-cut tooling cost. Its regular length classification and 1/2 inch shank diameter make it compatible with standard collet chucks, end mill holders, and milling machine spindles commonly found in job shop and production environments.

Key Features

• M42 cobalt high-speed steel construction for superior heat and wear resistance
• Double-end design provides two cutting ends per tool
• 30-degree right-hand spiral flute for efficient chip evacuation
• Center-cutting capability allows plunge entry cuts
• Bright/uncoated finish compatible with flood coolant and cutting oil
• Right-hand cutting direction suits standard milling machine spindle rotation

Compatibility

Designed for use in standard end mill holders and collet chucks accepting a 1/2 inch shank diameter. Suited for manual knee mills and CNC machining centers used in general-purpose ferrous metal milling.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered down and locked out per OSHA lockout/tagout procedures. Secure the shank fully into the holder to the recommended grip depth before tightening. Inspect the cutting edges for chips or damage before each use. Do not exceed the manufacturer-rated speeds and feeds for the workpiece material and tool diameter.
