Hertel E111004802 Ball End Mill 0.75in 2 Flute Hss

Product Description

The HERTEL E111004802 is a single-end ball end mill designed for contour milling, profiling, and 3D surface work in ferrous and non-ferrous materials. It is ground from M7 high speed steel and carries an uncoated finish. The cutting diameter is 0.75 inches with a 1.625-inch length of cut, a 3.875-inch overall length, and a matching 0.75-inch shank diameter. The two-flute, right-hand spiral geometry with a 37-degree helix angle balances chip evacuation and surface finish on a wide range of milling applications. Machinists and toolroom operators working on manual mills or CNC machining centers are the primary users of this tool.

This end mill is suited for general-purpose milling operations including slot milling, pocket roughing, and contoured surface finishing where a ball-nose profile is required. The regular-length body makes it appropriate for standard reach applications on vertical and horizontal milling machines. It is a practical choice for job shops, maintenance machining, and toolroom work where HSS tooling is preferred over carbide for interrupted cuts or re-sharpenability.

Key Features

• M7 high speed steel construction for toughness and re-sharpenability
• Ball-nose profile for contour milling and 3D surface work
• 37-degree right-hand spiral helix for efficient chip evacuation
• Two-flute design balances chip clearance and rigidity in slotting and profiling
• Uncoated finish suitable for a broad range of materials without coating-compatibility concerns
• Single-end configuration with a 0.75-inch shank for standard collet and end mill holder setups

Compatibility

Designed as a standard-shank single-end ball end mill for use in 0.75-inch collets, end mill holders, and shrink-fit toolholders on manual knee mills and CNC machining centers.

Installation Notes

Installation is performed by a machinist or toolroom technician using an appropriate end mill holder or collet system rated for the 0.75-inch shank diameter. Ensure the spindle is fully stopped and locked before changing tooling. Confirm runout with a dial indicator after seating the tool in the holder, as excessive runout accelerates wear on HSS end mills. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting tool length offsets and feed-and-speed parameters.
