Solid Micrograin Carbide End Mill 2 Flute Endmill EM2-0250

The Solid Micrograin Carbide End Mill is a type of milling cutter designed to be held by the shank on one end in order for it to cut with the opposite end. The advantage to an End Mill is that, unlike any other type of milling cutter, it is capable of cutting on the periphery, the face or the end of the cutter. Our offering of End Mills is extensive-ranging from conventional HSS, Cobalt, and Solid Carbide Roughing & Finishing Mills to application and material specific tools employing the latest geometries and coating technologies all resulting in improved efficiency and productivity for you. The number of flutes can range from two to eight. The fewer flutes offer the most efficient chip removal, but a higher amount of flutes provide a smoother finish. The End Mill’s helix angle is also important. Most general purpose End Mills have a 30-degree helix angle because it is halfway between “slow” (low-angle) and “fast” (high-angle) helix End Mills.

Specific projects require special styles of End Mills. Ball Nose End Mills are best for machining round bottom holes and complex contoured surfaces. Square Nose End Mills have square ends and are best for slotting, profiling, and roughing. Corner Radius End Mills have a square end with rounded corners on the cutting edges to reduce chipping. Double-ended End Mills have the same cutting edges and styles on both ends, doubling the tool’s life compared to Single-ended End Mills.

Cutter material is an important consideration when selecting an end mill. Carbide End Mills can run at higher speeds than high-speed or cobalt steel, it is also more resistant to wear and can be used at high cutting temperatures. Cobalt Steel End Mills resists abrasion and high cutting temperatures, and has higher feed rates than High-speed Steel. High-speed Steel End Mills are compatible with a variety of materials and is typically used for less demanding jobs.

An End Mill’s end cut type can either be center cutting or non-center cutting. Center-cutting end mills can create three-dimensional shapes and profiles, and make plunge cuts similar to a drill bit. All Carbide End Mills are center cutting. Non-center-cutting End Mills are suitable for peripheral milling and finishing, but cannot be used to make plunge cuts. HSS and Cobalt End Mills will specify if they are center or non-center cutting.
