Hertel E8053026 Square End Mill 13/32 in 4 Flute Hss Tin

Product Description

The HERTEL E8053026 is a double-end, four-flute square end mill engineered for general-purpose milling in high speed steel (HSS) grade M7. It measures 13/32 inch (0.4063 inches) in diameter with a 1/2 inch shank diameter and a 4-1/8 inch overall length. The tool features a 30-degree helix angle and a spiral flute geometry with a titanium nitride (TiN) coating that extends surface hardness and wear resistance. Centercutting capability allows plunge entry directly into workpiece material. Right-hand cut and right-hand flute orientation make this a standard configuration for conventional milling setups on manual mills and CNC machining centers.

This end mill is suited for ferrous and non-ferrous stock removal operations in job shops, tool rooms, and general manufacturing environments. The double-end design provides two usable cutting ends per tool, extending service life between replacements. A 1-inch length of cut accommodates typical shoulder and slot milling depths in the light-to-medium material removal range. Installation and use are handled by machinists and CNC operators working in metalworking production and maintenance machining applications.

Key Features

• Double-end design provides two cutting ends per tool for extended service life
• Centercutting geometry allows direct plunge milling without pre-drilling
• TiN coating increases surface hardness and reduces friction at the cutting edge
• 30-degree helix angle promotes smooth chip evacuation in spiral flute configuration
• M7 high speed steel construction balances toughness and wear resistance
• Right-hand cut and right-hand flute orientation for standard spindle compatibility

Compatibility

Designed as a standard shank end mill fitting 1/2 inch collets and end mill holders on manual knee mills, bridge mills, and CNC machining centers accepting straight-shank tooling.

Installation Notes

Installation is performed by qualified machinists using appropriate collet chucks or end mill holders torqued per toolholder manufacturer specifications. Confirm spindle direction matches the right-hand cut designation before engaging the workpiece. Ensure the tool is fully seated and secured in the holder to the correct gauge length before initiating a cut. Follow all machine guarding and personal protective equipment requirements per applicable shop safety standards.
