Choosing The Right Chamfer Cutter Tip Geometry

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 are used for chamfering or beveling any kind in a wide variety of materials. Many reasons exist for to chamfer an element, including fluid flow and safety, to part aesthetics.


Due to the diversity of needs, tooling manufacturers offer a variety of angles and sizes of chamfer cutters, and also several types of chamfer cutter tip geometries. Harvey Tool, as an illustration, 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” around 1 inch.

After obtaining a tool with the exact angle they’re searching for, a customer may need to choose a certain chamfer cutter tip that will be perfect for their operation. Common kinds of chamfer cutter tips include pointed, flat end, and end cutting. The subsequent three varieties of chamfer cutter tip styles, offered by Harvey Tool, each serve a unique purpose.

Three Kinds of Harvey Tool Chamfer Cutters

Type I: Pointed
This kind of chamfer cutter may be the only Harvey Tool option which will come to some sharp point. The pointed tip permits the cutter to execute in smaller grooves, slots, and holes, in accordance with one other 2 types. This style also provides for easier programming and touch-offs, because the point can be easily located. It’s because tip this form of the cutter has the longest length of cut (using the tool earning any finished point), when compared to flat end of the other sorts of chamfer cutters. Just a couple flute option, this is the most straightforward version of a chamfer cutter available from Harvey Tool.

Type II: Flat End, Non-End Cutting
Type II chamfer cutters are extremely like the type I style, but feature a conclusion that’s ground into an appartment, non-cutting tip. This flat “tip” removes the pointed section of the chamfer, which is the weakest area of the tool. Because of this alternation in tool geometry, it is given a different measurement for the way for a long time the tool can be whether or not this came to a spot. This measurement is recognized as “distance to theoretical sharp corner,” that helps using the programming from the tool. The benefit of the flat end from the cutter now provides for multiple flutes to exist around 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 used in narrow slots, but another advantage is really 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 much more advanced type of the kind II style. The sort III boasts a flat end tip with 2 flutes meeting in the center, making a center cutting-capable sort of the type II cutter. The very center cutting geometry of this cutter makes it possible to cut using its flat tip. This cutting allows the chamfer cutter to lightly reduce the top of a component towards the bottom of it, instead of leave material behind when cutting a chamfer. There are many situations where blending of a tapered wall and floor is needed, and that is where these chamfer cutters shine. The top diameter can also be held to a tight tolerance, which significantly supports programing it.

In conclusion, there may be many suitable cutters for any single job, and you will find many questions you should ask prior to picking your ideal tool. Choosing the right angle is dependant on making sure that the angle around the chamfer cutter matches the angle around the part. You need to be mindful of methods the angles are known as out, at the same time. Is the angle an “included angle” or “angle per side?” May be the angle cancelled with the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer and the longer along cut, these days, interference with walls or fixtures need to be considered. Flute count is dependant on material and handle. Softer materials have a tendency to want less flutes for better chip evacuation, while more flutes will be finish. After addressing each of these considerations, the right type of chamfer on your job needs to be abundantly clear.
