Hertel E5062012 Ball End Mill 0.1875 in 4 Flute Carbide

Product Description

The HERTEL E5062012 is a solid carbide ball end mill designed for precision milling operations in metal fabrication, moldmaking, and general machining. With a 0.1875 inch (3/16 inch) mill diameter and a 1.125 inch length of cut, this tool handles contour milling, slotting, and profile work in ferrous and non-ferrous materials. The 4-flute geometry with a 30-degree helix angle promotes smooth chip evacuation and stable cutting at higher feed rates. The bright, uncoated carbide construction is suited for dry machining or use with cutting fluids where coating adhesion is not required. Machinists and tool-and-die professionals specify this geometry for finishing passes on complex 3D surfaces.

This end mill is appropriate for use in CNC machining centers and manual mills where a single-end, right-hand cutting tool is specified. The 0.1875 inch shank diameter matches standard ER collet and end mill holder sizes common in production and job shop environments. The 3.0 inch overall length provides sufficient reach for typical cavity and pocket milling applications without excessive deflection. Right-hand flute direction suits standard spindle rotation on most vertical and horizontal machining centers.

Key Features

• 0.1875 inch mill diameter with matching 0.1875 inch shank for direct collet holding
• 4-flute design for improved surface finish and higher feed-rate capability versus 2-flute geometry
• 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Solid carbide construction for rigidity and wear resistance in demanding materials
• Bright, uncoated finish suitable for dry cutting or coolant-assisted machining
• Single-end configuration; right-hand cut and right-hand flute direction

Compatibility

Designed as a direct-fit replacement or standard selection for applications requiring a 3/16 inch diameter ball end mill with a 3/16 inch straight shank, compatible with ER collet chucks and end mill holders sized for 0.1875 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank to the recommended minimum engagement depth in the collet or holder and torque the retention nut per the toolholder manufacturer specifications. Inspect the cutting edge for chips or damage before use; do not run a damaged end mill.
