A chamfer cutter, or perhaps a chamfer mill, can be found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are pretty straight forward tools which might be useful for chamfering or beveling any kind within a wide array of materials. Many reasons exist to chamfer a part, including fluid flow and safety, to part aesthetics.

As a result of diversity of needs, tooling manufacturers offer many different angles and sizes of chamfer cutters, as well as different types of chamfer cutter tip geometries. Harvey Tool, as an example, offers 21 different angles per side, including 15° to 80°, flute counts of 2 in order to six, and shank diameters starting at 1/8” up to 1 “.

After locating a tool together with the exact angle they’re trying to find, a customer might have to select a certain chamfer cutter tip that will work best with their operation. Common kinds of chamfer cutter tips include pointed, flat end, and end cutting. The next three kinds of chamfer cutter tip styles, provided by Harvey Tool, each serve a unique purpose.

Three Varieties of Harvey Tool Chamfer Cutters

Type I: Pointed
This style of chamfer cutter is the only Harvey Tool option links to some sharp point. The pointed tip enables the cutter to execute in smaller grooves, slots, and holes, compared to the other two kinds. This style also provides for easier programming and touch-offs, since the point can be easily located. It’s due to the tip that sort of the cutter has got the longest amount of cut (together with the tool earning any finished point), compared to the flat end from the other chamfer cutters. With a two flute option, this is actually the most straightforward 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 as a result of a set, non-cutting tip. This flat “tip” removes the pointed section of the chamfer, which is weakest section of the tool. Due to this alteration of tool geometry, this tool is offered an additional measurement based on how a lot longer the tool would be whether or not this came to a spot. This measurement is termed “distance to theoretical sharp corner,” which assists with all the programming in the tool. The benefit of the flat end with the cutter now provides for multiple flutes to exist on the tapered profile of the chamfer cutter. With more flutes, this chamfer has improved tool life and handle. The flat, non-end cutting tip flat does limit its utilization in narrow slots, but an additional is often a lower profile angle with better angular velocity on the tip.

Type III: Flat End, End Cutting
Type III chamfer cutters are a much better and more advanced sort of the type II style. The type III boasts a flat end tip with 2 flutes meeting in the center, making a center cutting-capable form of the type II cutter. The very center cutting geometry on this cutter makes it possible to cut using its flat tip. This cutting allows the chamfer cutter to lightly reduce the top of the an element on the bottom of computer, rather than leave material behind when cutting a chamfer. There are numerous situations where blending of an tapered wall and floor should be used, and this is where these chamfer cutters shine. The top diameter can be held with a tight tolerance, which significantly aids in programing it.

In conclusion, there can be many suitable cutters for any single job, and there are many questions you have to ask before picking your ideal tool. Selecting the best angle relies on being sure that the angle about the chamfer cutter matches the angle around the part. You need to be aware of methods the angles are known as out, also. Is the angle an “included angle” or “angle per side?” Will be the angle called off in the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer and the longer the size of cut, but now, interference with walls or fixtures must be considered. Flute count depends upon material and handle. Softer materials usually want less flutes for much better chip evacuation, while more flutes will be finish. After addressing each one of these considerations, the right design of chamfer to your job needs to be abundantly clear.
