Categories and Utilizations
The features of the most prevalent end mill coating types are listed below. However, this list is not comprehensive. More specialized items are available for bespoke applications.
-
Flat / Square
The most often used types of end mills are square or flat. Profiling, slotting, side and face milling, and plunging are just a few of the many applications these tools excel in. Flat End Mills provide precise 90-degree corner cuts on the workpiece. Depending on the workpiece, they may be appropriate for roughing and finishing tasks.
-
Corner/Bull-Nose Radius
Bull-nose end mills are pretty similar to square end mills, except that their rounded edges assist disperse the cutting power uniformly. Excellent for grooves with flat bottoms and rounded inner corners. Feature slightly rounded edges that aid inappropriately distributing cutting forces to minimize blade damage and prolong its life. They can make flat-bottomed grooves with slightly rounded inner corners and are often used in mold milling.
-
Ball nose
The tip of Ball Nose End Mills is rounded. They are mainly used for 3D milling of contoured surfaces, groove rounding, pocketing, and other contouring operations. In addition, it can serve as the last trimmer for “finishing touches.”
-
Router / Tail of the Fish
If one end of an end mill bit is much thinner than the other, it is likely a fishtail or router end mill. Due to the tiny cutter form, this design can penetrate the material and create a flat surface without breaking out. They may also be used for pocketing, routing, and contouring.
-
Abrasive End Mill
As its name indicates, Roughing end mills rapidly remove a great deal of workpiece material, particularly during heavy cutting stages. They provide a rapid, rough finish with slight vibration, later refined by a separate cutter.
-
Chamfer Mill
There are two primary types of carbide chamfer cutters. The Flat Tip design has a flattened point to give the carbide chamfer cutter strength. The flat tip creates a tip diameter which is generally specified in the tool dimensions. The Pointed Tip design has a gashing that goes close to the center and has a small web. It is designed to get deeper into a hole than a Flat Tip design.
