Precision Twist E2302 Solid Carbide End Mills, Uncoated (Bright) Finish, 2 Flute, Square End, 1/2" Cutting Length, 5/16" Cutting Diameter Reviews
Precision Twist E2302 Solid Carbide End Mills, Uncoated (Bright) Finish, 2 Flute, Square End, 1/2" Cutting Length, 5/16" Cutting Diameter Feature
- Double-ended, having cutting teeth on both ends of the tool allows for quick change
- Uncoated (bright) finish tools have no additional surface treatment or coating, offering just the base (substrate) material for an economical alternative
- Carbide can run at higher speeds than high-speed steel (HSS), resisting abrasion and high cutting temperatures
- Two-flute design with efficient chip removal, suitable for side, face, slot, ramping, and plunge milling
- Short (also called stub) length, for usage where rigidity and lack of tool deflection are important
The Precision Twist E2302 series of end mills are a double-ended, stub length, square end, two-flute design which are made of carbide with a uncoated finish, used for high-speed machining with best performance in steel, stainless steel, cast iron, and copper.
Doubled-ended end mills have cutting teeth on both ends. Make sure your tool holder can accommodate this style. When one end gets dull or damaged, you can flip the tool around and use the other end.
Uncoated tools have no finish or coating. They are a common choice for general use applications. The stub length offers maximum rigidity and minimum tool deflection. Good for use with heavy feed rates in shallow slots. The carbide material offers many advantages over HSS such as faster feed rates due to its hardness. They can be run several times faster than HSS. Carbide’s high heat and wear resistance help extend the life of the tool and increase productivity.
Square end mills are very versatile with the ability to machine in three dimensions and the two-flute design allows for a large chip space and easy chip removal. While the surface finish is not as smooth as a three- or four-flute design, they are very good for heavy-duty, large material removal operations. Most end mills have a 30-degree spiral helix angle, which is good for working with a wide range of materials.
End mills are designed to remove material and create three-dimensional shapes or 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 make plunge cuts similar to a drill bit.
Precision manufactures machine tools under the following brands: Precision Twist, Precision Dormer, and Union Butterfield. They have locations around the world, and provide tools adhering to ANSI, NAS, and DIN standards.
