Hertel GG110956 Ball End Mill 7/8 in 2 Flute Hss

Product Description

The HERTEL GG110956 is a single-end ball end mill designed for contouring, profiling, and finishing operations on a wide range of materials. It is constructed from M7 high speed steel with a bright, uncoated finish, making it well suited for general-purpose milling where coating is not required. The mill measures 0.875 inches in diameter with a 2-inch length of cut and a 3/4-inch shank diameter, giving it a stable tool-to-spindle interface. The 30-degree helix angle and two-flute spiral configuration support efficient chip evacuation and smooth cutting action. This tool is installed and used by machinists, tool and die makers, and CNC operators working in job shops and production environments.

This ball end mill is applicable in vertical and horizontal milling centers, manual mills, and CNC machining operations targeting ferrous and non-ferrous metals as well as plastics. The two-flute geometry provides adequate gullet space for chip clearance, which is particularly useful when cutting slots or working in softer materials where chip packing is a concern. The right-hand cutting and right-hand flute direction conform to standard spindle rotation on most milling platforms. It is suited to finish-pass and semi-finish contouring work where a ball-nose profile is required.

Key Features

• 0.875-inch (7/8 inch) ball nose diameter for radius contouring and profiling
• M7 high speed steel construction provides toughness and wear resistance in general milling applications
• 2-inch length of cut accommodates moderate depth-of-cut requirements
• 30-degree helix angle promotes smooth cutting action and efficient chip flow
• Two-flute spiral design with right-hand cut and right-hand helix for standard spindle compatibility
• Bright, uncoated finish suitable for use with cutting fluids on a broad material range
• Single-end configuration with 3/4-inch straight shank for secure collet or end mill holder retention

Compatibility

Designed as a standard single-end ball end mill with a 3/4-inch straight shank, compatible with collets, end mill holders, and milling chucks sized for 3/4-inch shank tooling on vertical mills, horizontal mills, and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the spindle fully stopped and machine power isolated before tool changes. The shank should be fully seated in the collet or holder to the minimum insertion depth recommended by the toolholder manufacturer, leaving no more shank exposed than necessary. Verify runout with an indicator after clamping before beginning a cut. Follow applicable shop safety practices and machine manufacturer guidelines for speeds, feeds, and depth of cut for the workpiece material.
