Hertel 62851910 Roughing End Mill 3/16 in 4 Flute Cobalt

Product Description

The HERTEL 62851910 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it delivers heat and wear resistance suitable for cutting harder ferrous and non-ferrous workpiece materials. The 3/16 inch cutting diameter is paired with a coarse-pitch spiral flute geometry that breaks chips efficiently and reduces cutting forces. A TiCN coating adds surface hardness and lubricity, extending tool life in production environments. This tool is typically installed and operated by machinists and tool-and-die professionals on manual or CNC milling equipment.

This roughing end mill suits light-duty roughing passes on small-diameter features in ferrous alloys, stainless steels, and similar hard materials. The 1/2 inch length of cut and 3/8 inch shank diameter make it appropriate for use in standard collet chucks or end mill holders on vertical milling machines and machining centers. The right-hand cutting direction and right-hand flute spiral are the conventional configuration for standard spindle setups.

Key Features

• M42 cobalt HSS construction for elevated heat resistance during high-feed roughing cuts
• TiCN coating increases surface hardness and reduces friction at the cutting edge
• Coarse-pitch spiral flute geometry promotes chip evacuation and lowers cutting forces
• Center-cutting design allows plunge entry into the workpiece
• 3/8 inch shank diameter fits standard collet and end mill holder tooling
• Single-end configuration with right-hand cut and right-hand flute direction

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for standard milling applications requiring a 3/16 inch cutting diameter and 3/8 inch shank in vertical milling machines or CNC machining centers.

Installation Notes

Installation is performed by a qualified machinist. Power down and lock out the spindle before seating or removing the tool from the holder. Ensure the shank is fully seated and the collet or set-screw holder is torqued according to the toolholder manufacturer specifications before operation. Inspect the cutting edges for chips or wear before each use and replace when the TiCN coating shows significant breakdown or edge deformation.
