A chamfer cutter, or perhaps a chamfer mill, can be found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are quite obvious tools which might be used for chamfering or beveling any kind within a wide variety of materials. Many reasons exist to chamfer a part, starting from fluid flow and safety, to part aesthetics.

Due to the diversity of needs, tooling manufacturers offer many different angles and sizes of chamfer cutters, as well as a variety of chamfer cutter tip geometries. Harvey Tool, as an example, offers 21 different angles per side, which range from 15° to 80°, flute counts of 2 to 6, and shank diameters starting at 1/8” as much as 1 inch.

After obtaining a tool together with the exact angle they’re searching for, a client may need to go with a certain chamfer cutter tip that could work best with their operation. Common varieties of chamfer cutter tips include pointed, flat end, and end cutting. The next three types of chamfer cutter tip styles, provided by Harvey Tool, each serve a distinctive purpose.

Three Types of Harvey Tool Chamfer Cutters

Type I: Pointed
This brand of chamfer cutter is the only Harvey Tool option which will come with a sharp point. The pointed tip permits the cutter to perform in smaller grooves, slots, and holes, when compared with one other 2 types. This style also permits easier programming and touch-offs, since the point can easily be located. It’s because of its tip that sort of the cutter gets the longest period of cut (together with the tool creating any finished point), when compared to the flat end in the other chamfer cutters. With only a couple of flute option, here is the most simple sort of a chamfer cutter made available from Harvey Tool.

Type II: Flat End, Non-End Cutting
Type II chamfer cutters are very just like the type I style, but feature a stop that’s ground right down to a flat, non-cutting tip. This flat “tip” removes the pointed section of the chamfer, the actual weakest part of the tool. Because of this alternation in tool geometry, this tool emerged yet another measurement for how for a long time the tool could be whether it found an area. This measurement is known as “distance to theoretical sharp corner,” which assists with the programming of the tool. The benefit of the flat end in the cutter now provides for multiple flutes to exist around the tapered profile in the chamfer cutter. With increased flutes, this chamfer has improved tool life and finished. The flat, non-end cutting tip flat does limit its use within narrow slots, but another advantage is really a lower profile angle with better angular velocity at the tip.

Type III: Flat End, End Cutting
Type III chamfer cutters are a much better plus more advanced type of the kind of II style. The kind of III boasts a flat end tip with 2 flutes meeting in the center, creating a center cutting-capable sort of the sort II cutter. The middle cutting geometry of this cutter can help you cut having its flat tip. This cutting allows the chamfer cutter to lightly cut into the top of an element to the bottom of computer, as an alternative to leave material behind when cutting a chamfer. There are numerous situations where blending of an tapered wall and floor is necessary, and that is where these chamfer cutters shine. The end diameter can be held into a tight tolerance, which significantly is great for programing it.

To summarize, there might be many suitable cutters to get a single job, and there are many questions you should ask before picking your ideal tool. Deciding on the best angle comes down to being sure that the angle for the chamfer cutter matches the angle around the part. One needs to use caution of how the angles are classified as out, as well. Could be the angle an “included angle” or “angle per side?” Is the angle called off from the vertical or horizontal? Next, the larger the shank diameter, the stronger the chamfer along with the longer the size of cut, the good news is, interference with walls or fixtures need to be considered. Flute count is dependant on material and finished. Softer materials have a tendency to want less flutes for much better chip evacuation, while more flutes will be finish. After addressing these considerations, the proper type of chamfer on your job must be abundantly clear.
