roughing end mill - side and front view
Roughing End Mills are designed for roughing or hogging large amounts of metal prior to a finish mill operation. They are also known as Hogging End Mills.
ROUGHING END MILLS
Super (M2-AL) Roughing End Mills page 268
Super (M2-AL) High Speed Steel Roughing End Mills are designed for roughing or hogging large amounts of metal prior to a finish mill operation. M2-Al High Speed Steel is a premium alloy formed by adding aluminum to the base chemical composition of M2 HSS to extend tool life and to dissipate heat. It is often referred to as "Super Steel."
Cobalt (M42) Roughing End Mills page 268
Cobalt Roughing End Mills are designed for roughing or hogging large amounts of metal prior to a finish milling operation. They are used for deep slotting or heavy side cuts and require less power than conventional end mills. Ideal for machining high alloyed steels, titanium alloys, and cast alloys. Form-relieved edges stay constant and can be resharpened by grinding the faces. Roughing End Mills are also known as Hogging End Mills.
SOLID CARBIDE ROUGHING END MILLS
Solid Carbide Roughing End Mills - Type "A" page 269
Type "A" Solid Carbide Roughing End Mills are designed with a special tool geometry for maximum stock removal when milling aluminum, brass, and copper alloys. Corner radius design eliminates corner chipping.
Solid Carbide Roughing End Mills - Type "N" page 269
Type "N" Solid Carbide Roughing End Mills are designed with a special tool geometry for maximum stock removal when milling Titanium, Inconl, Rene, Waspaloy, and high temperature nickel base alloys.  Corner radius design eliminates corner chipping.
Solid Carbide Roughing End Mills - Type "S" page 269
Type "S" Solid Carbide Roughing End Mills are designed with a special tool geometry for maximum stock removal when milling mild steel, steel alloys, stainless steel, and cast iron.  Corner radius design eliminates corner chipping.
