Hertel E1050048 Square End Mill 0.75in 2 Flute Hss

Product Description

The HERTEL E1050048 is a double-end, square-profile end mill designed for milling operations in metal and general-purpose machining applications. Built from M7 high speed steel, it runs uncoated with a 30-degree spiral flute helix that promotes efficient chip evacuation and consistent cutting performance. The tool measures 0.75 inches in diameter with a 1.3125-inch length of cut and a 5-inch overall length. With two flutes and a centercutting geometry, it handles both peripheral and plunge cuts. Right-hand cut and right-hand flute orientation are standard. Machinists and tool-and-die professionals working on manual or CNC mills rely on this type of tool for slotting, profiling, and light pocketing work.

This end mill fits typical vertical and horizontal milling setups where a 0.75-inch shank diameter is required. The regular-length configuration suits standard workholding depths without the clearance demands of long-reach tooling. The double-end design extends usable tool life, allowing the operator to flip to the second cutting end once the first shows wear. It is suited for ferrous and non-ferrous metals in job shop, maintenance, and production environments where HSS tooling is preferred over carbide for interrupted cuts or older equipment with less rigid spindle systems.

Key Features

• M7 high speed steel construction for toughness in interrupted and general-purpose cuts
• Double-end design provides two usable cutting ends per tool
• 30-degree helix spiral flute promotes chip flow and reduces cutting heat
• Centercutting geometry enables direct plunge entry without a pilot hole
• Uncoated finish suitable for re-sharpening in-house
• Right-hand cut and right-hand flute, standard orientation for conventional milling setups

Compatibility

Designed as a standard 0.75-inch shank square end mill compatible with milling machine spindles, collet chucks, and end mill holders accepting a 0.75-inch straight shank.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism to the equipment manufacturer specification. Verify runout with a dial indicator before beginning a cut, particularly with HSS tooling where concentricity affects tool life.
