Hertel E5249056 Ball End Mill 0.875 in 2 Flute Solid Carbide

Product Description

The HERTEL E5249056 is a solid carbide ball end mill designed for precision milling operations in metal, composites, and hard materials. With a 0.875 inch mill diameter and a 1.5 inch length of cut, this single-end tool delivers accurate profiling, contouring, and 3D surface milling. The 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces. At 4 inches overall length with a matching 0.875 inch shank diameter, it mounts securely in standard end mill holders. The 2-flute geometry provides clearance for chip flow, making it well suited for slotting and ramping cuts. No coating is applied, keeping the carbide substrate exposed for applications where coating is not required or preferred.

This ball end mill is used in CNC machining centers and manual mills for finish profiling, die and mold work, and contoured surface generation. The right-hand cutting and right-hand flute direction make it compatible with standard CNC spindle configurations. Machinists in tool and die, aerospace component, and general precision machining shops will find this tool appropriate for both roughing passes at conservative depths and finish passes on complex geometry. It is sold as a single-end tool, meaning the cutting geometry is on one end only.

Key Features

• 0.875 inch mill diameter with matching 0.875 inch shank for rigid, concentric tool holding
• 1.5 inch length of cut supports profiling and slotting at moderate axial depths
• Solid carbide construction provides hardness and wear resistance superior to high-speed steel
• 30-degree helix angle promotes efficient chip evacuation and smooth cutting action
• 2-flute geometry allows chip clearance in slot milling and plunge entry applications
• Uncoated finish suitable for applications where substrate exposure is preferred or coating is not specified
• Right-hand cut and right-hand flute direction compatible with standard CNC and manual mill spindles

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard end mill holders and collet chucks accepting a 0.875 inch shank diameter.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Before mounting, ensure the spindle is fully stopped and the machine is in a safe, locked-out state. Seat the shank fully into the holder and torque the set screw or collet nut to the tool holder specification. Inspect the cutting edges for chips or damage before running the first pass.
