Picking The Proper Chamfer Cutter Tip Geometry

A chamfer cutter, or possibly a chamfer mill, are available at any machine shop, assembly floor, or hobbyist’s garage. These cutters are quite obvious tools which are employed for chamfering or beveling any area in the wide range of materials. A lot of to chamfer an important part, which range from 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, as well as different types of chamfer cutter tip geometries. Harvey Tool, for instance, offers 21 different angles per side, starting from 15° to 80°, flute counts of two to, and shank diameters starting at 1/8” around One inch.

After finding a tool together with the exact angle they’re seeking, a client may have to select a certain chamfer cutter tip that could be perfect for their operation. Common forms of chamfer cutter tips include pointed, flat end, and end cutting. The subsequent three varieties of chamfer cutter tip styles, available from Harvey Tool, each serve an original purpose.

Three Kinds of Harvey Tool Chamfer Cutters

Type I: Pointed
This form of chamfer cutter is the only Harvey Tool option which comes into a sharp point. The pointed tip enables the cutter to execute in smaller grooves, slots, and holes, when compared with the other 2 types. This style also provides for easier programming and touch-offs, because the point can be located. It’s because tip until this form of the cutter has the longest period of cut (together with the tool creating any finished point), when compared to the flat end from the other kinds of chamfer cutters. With only a 2 flute option, here is the most simple version of a chamfer cutter available from Harvey Tool.

Type II: Flat End, Non-End Cutting
Type II chamfer cutters are very exactly like the type I style, but feature a stop that’s ground down to an appartment, non-cutting tip. This flat “tip” removes the pointed the main chamfer, the weakest section of the tool. Due to this difference in tool geometry, this tool emerged yet another measurement for a way much longer the tool would be when it found a place. This measurement is termed “distance to theoretical sharp corner,” which helps using the programming in the tool. The benefit of the flat end in the cutter now allows for multiple flutes to exist for the tapered profile in the chamfer cutter. With increased 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 benefit is a lower profile angle with better angular velocity with the tip.

Type III: Flat End, End Cutting
Type III chamfer cutters are a greater and more advanced sort of the kind II style. The kind of III possesses a flat end tip with 2 flutes meeting at the center, setting up a center cutting-capable form of the kind II cutter. The very center cutting geometry of the cutter can help you cut using its flat tip. This cutting permits the chamfer cutter to lightly reduce the top a part to the bottom of it, rather than leave material behind when cutting a chamfer. There are numerous situations where blending of your tapered wall and floor is required, which is where these chamfer cutters shine. The end diameter is also held into a tight tolerance, which significantly is great for programing it.

In conclusion, there may be many suitable cutters for the single job, and you will find many questions you need to ask prior to 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. You should be mindful of precisely how the angles are known as out, as well. Will be the angle an “included angle” or “angle per side?” May be the angle cancelled in the vertical or horizontal? Next, the larger the shank diameter, the stronger the chamfer along with the longer the length of cut, the good news is, interference with walls or fixtures must be considered. Flute count is dependant on material and finish. Softer materials often want less flutes for better chip evacuation, while more flutes will help with finish. After addressing these considerations, the correct type of chamfer on your job must be abundantly clear.
