About Dormer 0412282 Cobalt Steel Square Nose End
The Dormer C191 gold oxide-finished cobalt steel square end mill has a threaded shank, two flutes, and a 30-degree helix angle for general-purpose machining on a range of materials. The two flutes have better chip-carrying capacity than end mills with more flutes while offering additional support when the tool goes deep into the material in applications with a high depth of cut. The gold oxide finish is a low-temperature heat treatment that reduces grinding stress within the tool. The cobalt steel substrate can be run at faster speeds and stays sharp longer than high-speed steel tools, while offering resistance to heat and abrasion. The tool’s square end creates sharp, unrounded cuts. The 30-degree helix angle supports general-purpose applications. It balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action. The center-cutting design has cutting teeth at the end of the tool, so it can be fed into the workpiece like a drill bit and used for applications such as slotting and milling. This tool has a threaded shank for security when used with coordinating toolholders. End mills are designed to remove material and create multi-dimensional shapes and profiles. They have cutting edges along the outside diameter and flutes that remove chips from the cutting area and allow cooling fluids to enter. If heat is not reduced effectively, the tool’s cutting edges will dull and additional material buildup can occur. The number of flutes can range from two to eight. Two-flute designs offer the most efficient chip removal, but more flutes provide a smoother finish. The shank is the end of the tool held in place by a tool holder or machine. Center-cutting end mills can create three-dimensional shapes and profiles, and make plunge cuts similar to a drill bit. Non-center-cutting end mills are for applications such as peripheral milling and finishing, but cannot make plunge cuts. Dormer Pramet manufactures cutting tools under the following brands: Precision Twist Drill, Dormer, Union Butterfield and Pramet. The company has locations around the world, and provides tools adhering to ANSI, NAS, and DIN standards.
