Selecting The Right Chamfer Cutter Tip Geometry




A chamfer cutter, or possibly a chamfer mill, is available at any machine shop, assembly floor, or hobbyist’s garage. These cutters are simple tools which are employed for chamfering or beveling any area within a wide selection of materials. There are many reasons to chamfer a component, including fluid flow and safety, to part aesthetics.


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

After locating a tool using the exact angle they’re trying to find, a client may have to select a certain chamfer cutter tip that will best suit their operation. Common kinds of chamfer cutter tips include pointed, flat end, and end cutting. These three varieties of chamfer cutter tip styles, provided by Harvey Tool, each serve a unique purpose.

Three Forms of Harvey Tool Chamfer Cutters

Type I: Pointed
This kind of chamfer cutter will be the only Harvey Tool option which comes to some sharp point. The pointed tip enables the cutter to complete in smaller grooves, slots, and holes, in accordance with the other two types. This style also allows for easier programming and touch-offs, since the point can easily be located. It’s due to the tip until this type of the cutter has got the longest period of cut (using the tool coming to a finished point), in comparison to the flat end with the other kinds of chamfer cutters. Just a 2 flute option, this can be the easiest form of a chamfer cutter provided by Harvey Tool.

Type II: Flat End, Non-End Cutting
Type II chamfer cutters are extremely exactly like the type I style, but feature an end that’s ground down to an appartment, non-cutting tip. This flat “tip” removes the pointed area of the chamfer, the weakest area of the tool. Because of this difference in tool geometry, this tool emerges an additional measurement for how for a long time the tool would be whether it located a point. This measurement is termed “distance to theoretical sharp corner,” which assists with the programming of the tool. The main advantage of the flat end from the cutter now enables multiple flutes to exist about the tapered profile in the chamfer cutter. With more flutes, this chamfer has improved tool life and take care of. The flat, non-end cutting tip flat does limit its use within narrow slots, but another advantage is 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 much more advanced form of the kind of II style. The kind III possesses a flat end tip with 2 flutes meeting in the center, setting up a center cutting-capable version of the sort II cutter. The very center cutting geometry on this cutter makes it possible to cut having its flat tip. This cutting enables the chamfer cutter to lightly cut into the top of an element towards the bottom of it, as opposed to leave material behind when cutting a chamfer. There are several situations where blending of an tapered wall and floor is required, which is where these chamfer cutters shine. The tip diameter is also held to a tight tolerance, which significantly supports programing it.

In conclusion, there may be many suitable cutters for the single job, and you will find many questions you have to ask ahead of picking your ideal tool. Selecting the most appropriate angle depends upon ensuring that the angle around the chamfer cutter matches the angle about the part. One needs to be mindful of methods the angles these are known as out, too. Is the angle an “included angle” or “angle per side?” Is the angle cancelled in the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer and the longer the length of cut, however, interference with walls or fixtures should be considered. Flute count depends upon material and finish. Softer materials have a tendency to want less flutes for better chip evacuation, while more flutes will help with finish. After addressing all these considerations, the proper type of chamfer on your job needs to be abundantly clear.
