Hertel 06822043 Roughing End Mill 1 in 5 Flute Cobalt Tin

Product Description

The HERTEL 06822043 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel and finished with a titanium nitride (TiN) coating, this tool handles tough ferrous and non-ferrous materials with extended tool life compared to standard HSS tooling. The 1-inch diameter cutter carries 5 flutes in a right-hand cutting, right-hand flute configuration and delivers a 1.875-inch length of cut. The 0.75-inch shank fits standard milling machine collets and toolholders. This is a non-centercutting tool intended for peripheral and slotting cuts where plunge entry is not required. Machinists and tool-and-die professionals are the primary users.

This end mill is suited for roughing passes on knee mills, CNC vertical machining centers, and bridgeport-style machines in job shop, maintenance, and production environments. The regular-length geometry keeps the tool rigid during heavy chip-load passes, making it practical for steel, cast iron, stainless, and similar materials. The 5-flute count increases feed rate potential compared to 4-flute designs while the roughing geometry breaks chips efficiently and reduces cutting forces on the workpiece.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance over standard M2 HSS
• TiN coating reduces friction and extends edge life on ferrous materials
• 5-flute roughing geometry promotes chip breaking and higher feed rates
• Right-hand cut, right-hand helix for standard spindle direction compatibility
• 0.75-inch shank diameter fits common collet and toolholder sizes
• Regular-length body maintains rigidity during heavy roughing passes

Compatibility

Designed as an OEM-style roughing end mill for use in standard milling machine spindles accepting a 0.75-inch shank diameter. Verify toolholder runout and collet condition before use.

Installation Notes

Installation is performed by machinists or tool-and-die technicians using an appropriate collet or end mill holder. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the recommended engagement depth for the toolholder in use. This tool is not centercutting and must not be used for direct plunge entry into solid material.
