Key Features

  • Suitable for machining steel, hardened steel, steel alloys, stainless steel, cast iron, copper, brass, bronze, aluminum, and aluminum alloys
  • Two flutes offer better chip-carrying capacity than end mills with more flutes, enhancing the tool's ability to remove material
  • Carbide can run at higher speeds than high-speed or cobalt steel, resisting wear and high cutting temperatures
  • Uncoated (bright) tools have no additional surface treatment or coating for use on a range of materials
  • Ball nose end mills (also called ball end) create contoured surfaces¬≠¬≠¬≠

Product Description

The Precision Twist EB3302 uncoated carbide ball nose end mill has two flutes and a 30-degree helix for machining steel, hardened steel, steel alloys, stainless steel, cast iron, copper, brass, bronze, aluminum, and aluminum alloys. 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 tool’s ball nose creates contoured surfaces, where sharp corners are not required. 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.

Carbide is harder than high-speed or cobalt steel, making it more wear resistant at high speeds and providing longer tool life. This tool has no coating or surface treatment. Cutting diameter tolerance is + 0.000 to - 0.002". The round shank accommodates a range of tool holders.

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.

Precision Dormer manufactures cutting tools under the brands Precision Twist, Dormer, and Union Butterfield. The company, headquartered in Crystal Lake, IL, meets International Organization for Standardization (ISO) 9001 and 14000 standards.
