Selecting The Right Chamfer Cutter Tip Geometry

A chamfer cutter, or even a chamfer mill, is available at any machine shop, assembly floor, or hobbyist’s garage. These cutters are simple tools which are useful for chamfering or beveling any part inside a wide selection of materials. A lot of to chamfer a part, including fluid flow and safety, to part aesthetics.


As a result of diversity of needs, tooling manufacturers offer numerous angles and sizes of chamfer cutters, and as well as different types of chamfer cutter tip geometries. Harvey Tool, for instance, offers 21 different angles per side, which range from 15° to 80°, flute counts of two in order to six, and shank diameters starting at 1/8” approximately 1 “.

After finding a tool with the exact angle they’re searching for, a customer might have to go with a certain chamfer cutter tip that would best suit their operation. Common forms of chamfer cutter tips include pointed, flat end, and end cutting. These three types of chamfer cutter tip styles, available from Harvey Tool, each serve an original purpose.

Three Forms of Harvey Tool Chamfer Cutters

Type I: Pointed
This brand of chamfer cutter could be the only Harvey Tool option links to a sharp point. The pointed tip allows the cutter to complete in smaller grooves, slots, and holes, compared to the other two sorts. This style also permits easier programming and touch-offs, because the point can easily be located. It’s due to the tip that this version of the cutter has got the longest amount of cut (with the tool creating any finished point), when compared to flat end from the other types of chamfer cutters. With a two flute option, here is the most basic sort of a chamfer cutter offered by Harvey Tool.

Type II: Flat End, Non-End Cutting
Type II chamfer cutters are extremely 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 part of the chamfer, which is the weakest area of the tool. For this reason difference in tool geometry, it is given yet another measurement for how for a long time the tool will be whether or not this came to a point. This measurement is called “distance to theoretical sharp corner,” which will help with the programming from the tool. The benefit of the flat end with the cutter now provides for multiple flutes to exist for the tapered profile from the chamfer cutter. With an increase of 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 can be a lower profile angle with better angular velocity with the tip.

Type III: Flat End, End Cutting
Type III chamfer cutters are an improved and more advanced type of the kind II style. The kind III boasts a flat end tip with 2 flutes meeting at the center, developing a center cutting-capable type of the sort II cutter. The very center cutting geometry on this cutter makes it possible to cut using its flat tip. This cutting permits the chamfer cutter to lightly cut into the top a component on the bottom of computer, as opposed to leave material behind when cutting a chamfer. There are several situations where blending of an tapered wall and floor is needed, which is where these chamfer cutters shine. The top diameter is also held to a tight tolerance, which significantly is great for programing it.

To conclude, there may be many suitable cutters for the single job, and you will find many questions you have to ask prior to picking your ideal tool. Selecting the best angle is dependant on being sure that the angle on the chamfer cutter matches the angle for the part. You need to be cautious of the way the angles are classified as out, also. Will be the angle an “included angle” or “angle per side?” May be the angle cancelled of the vertical or horizontal? Next, the larger the shank diameter, the stronger the chamfer along with the longer the size of cut, but now, interference with walls or fixtures must be considered. Flute count comes down to material and handle. Softer materials have a tendency to want less flutes for better chip evacuation, while more flutes will be finish. After addressing these considerations, the right design of chamfer for your job needs to be abundantly clear.
