Hertel 87646642 Cobalt End Mill Set 5 Piece Square End

Product Description

The HERTEL 87646642 is a 5-piece cobalt end mill set designed for milling operations requiring durability and heat resistance. Each end mill features a 4-flute, single-end, square-end geometry with a bright uncoated finish. The set is manufactured from M42 cobalt high-speed steel, a material grade well-suited for cutting harder workpiece materials and applications that generate elevated tool temperatures. The fine pitch flute design supports smooth chip evacuation in a range of ferrous and non-ferrous materials. Machinists and tooling professionals select this set when a variety of end mill diameters are needed for production or maintenance work.

This set includes end mills in five diameters: 3/8 inch, 1/2 inch, 5/8 inch, 3/4 inch, and 1 inch. It is suited for use in vertical machining centers, knee mills, and manual or CNC milling machines in job shop, maintenance, and production environments. The square-end profile makes it appropriate for slotting, profiling, and peripheral milling operations in general metalworking applications. The set is packaged as a single unit and is intended for professional machinists and toolroom technicians.

Installation Notes

End mills should be installed and removed by a qualified machinist following proper toolholding procedures. Ensure the machine spindle is fully powered down and locked out before changing tooling. Use appropriate collets or end mill holders rated for the shank diameter of each cutter. Verify runout with a dial indicator after installation before beginning a cut.
