A chamfer cutter, or perhaps a chamfer mill, is found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are quite obvious tools which might be useful for chamfering or beveling any area inside a wide range of materials. Many reasons exist to chamfer an important part, ranging from fluid flow and safety, to part aesthetics.
Due to the 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, for instance, offers 21 different angles per side, which range from 15° to 80°, flute counts of 2 to 6, and shank diameters starting at 1/8” approximately 1 “.
After locating a tool using the exact angle they’re looking for, an individual may have to go with a certain chamfer cutter tip that would work best with their operation. Common kinds of chamfer cutter tips include pointed, flat end, and end cutting. The next three varieties of chamfer cutter tip styles, provided by Harvey Tool, each serve an exceptional purpose.
Three Forms of Harvey Tool Chamfer Cutters
Type I: Pointed
This style of chamfer cutter may be the only Harvey Tool option that comes into a sharp point. The pointed tip permits the cutter to perform in smaller grooves, slots, and holes, compared to one other two kinds. This style also allows for easier programming and touch-offs, since the point can be easily located. It’s due to the tip that sort of the cutter contains the longest duration of cut (with the tool creating any finished point), in comparison to the flat end of the other types of chamfer cutters. With simply a couple flute option, here is the most straightforward form of a chamfer cutter available from Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are very similar to the type I style, but feature a stop that’s ground down to an appartment, non-cutting tip. This flat “tip” removes the pointed section of the chamfer, the weakest section of the tool. For that reason change in tool geometry, this tool is offered a different measurement for the way for a long time the tool would be whether it located a spot. This measurement is known as “distance to theoretical sharp corner,” which will help with the programming from the tool. The main benefit of the flat end from the cutter now provides for multiple flutes to exist on the tapered profile with the chamfer cutter. With more flutes, this chamfer has improved tool life and finished. The flat, non-end cutting tip flat does limit its use in narrow slots, but an additional advantage is often a lower profile angle with better angular velocity at the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are a better plus more advanced form of the kind of II style. The kind of III features a flat end tip with 2 flutes meeting in the center, developing a center cutting-capable form of the kind of II cutter. The middle cutting geometry on this cutter can help you cut using its flat tip. This cutting enables the chamfer cutter to lightly cut into the top an element on the bottom from it, instead of leave material behind when cutting a chamfer. There are lots of situations where blending of an tapered wall and floor is required, and that is where these chamfer cutters shine. The end diameter is also held to some tight tolerance, which significantly helps with programing it.
In summary, there can be many suitable cutters for any single job, and you will find many questions you should ask before picking your ideal tool. Selecting the best angle comes down to ensuring the angle around the chamfer cutter matches the angle around the part. You should be aware of precisely how the angles are known as out, too. Could be the angle an “included angle” or “angle per side?” Could be the angle cancelled from the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer and also the longer along cut, but now, interference with walls or fixtures need to be considered. Flute count depends upon material and take care of. 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 correct style of chamfer for the job needs to be abundantly clear.
