Selecting The Proper Chamfer Cutter Tip Geometry




A chamfer cutter, or possibly a chamfer mill, can be found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are quite obvious tools which can be utilized for chamfering or beveling any part within a wide range of materials. There are many reasons to chamfer an element, ranging from fluid flow and safety, to part aesthetics.


Due to diversity of needs, tooling manufacturers offer a number of angles and sizes of chamfer cutters, and as well as various kinds of chamfer cutter tip geometries. Harvey Tool, as an illustration, offers 21 different angles per side, ranging from 15° to 80°, flute counts of 2 in order to six, and shank diameters starting at 1/8” up to 1 inch.

After obtaining a tool with all the exact angle they’re searching for, a person might have to choose a certain chamfer cutter tip that might best suit their operation. Common kinds of chamfer cutter tips include pointed, flat end, and end cutting. These three forms of chamfer cutter tip styles, available from Harvey Tool, each serve an exceptional purpose.

Three Types of Harvey Tool Chamfer Cutters

Type I: Pointed
This kind of chamfer cutter will be the only Harvey Tool option links to some sharp point. The pointed tip permits the cutter to complete in smaller grooves, slots, and holes, relative to the other two types. This style also permits easier programming and touch-offs, since the point can easily be located. It’s because of its tip that type of the cutter contains the longest length of cut (with all the tool coming to a finished point), compared to the flat end in the other chamfer cutters. With only a couple of flute option, this can be the most simple sort of a chamfer cutter provided by Harvey Tool.

Type II: Flat End, Non-End Cutting
Type II chamfer cutters are extremely similar to the type I style, but feature an end that’s ground as a result of a set, non-cutting tip. This flat “tip” removes the pointed part of the chamfer, which is weakest the main tool. For that reason alteration of tool geometry, it is given yet another measurement for a way much longer the tool can be whether or not this located an area. This measurement is termed “distance to theoretical sharp corner,” which helps with the programming of the tool. The main benefit of the flat end from the cutter now allows for multiple flutes to exist about the tapered profile from the chamfer cutter. With an increase of flutes, this chamfer has improved tool life and finish. The flat, non-end cutting tip flat does limit its use within narrow slots, but an additional is really a lower profile angle with better angular velocity with the tip.

Type III: Flat End, End Cutting
Type III chamfer cutters are a better plus much more advanced version of the kind of II style. The type III boasts a flat end tip with 2 flutes meeting in the center, developing a center cutting-capable form of the kind of II cutter. The guts cutting geometry with this cutter enables us to cut using its flat tip. This cutting permits the chamfer cutter to lightly cut into the very top of an important part for the bottom of it, as an alternative to leave material behind when cutting a chamfer. There are several situations where blending of your tapered wall and floor should be used, which is where these chamfer cutters shine. The tip diameter can also be held into a tight tolerance, which significantly is great for programing it.

To conclude, there can be many suitable cutters to get a single job, and there are many questions you must ask just before picking your ideal tool. Choosing the right angle is dependant on ensuring the angle for the chamfer cutter matches the angle about the part. One needs to be cautious of the way the angles are called out, also. Will be the angle an “included angle” or “angle per side?” Could be the angle called off with the vertical or horizontal? Next, the better the shank diameter, the stronger the chamfer and also the longer the duration of cut, however, interference with walls or fixtures need to be considered. Flute count depends upon material and finished. Softer materials often want less flutes for better chip evacuation, while more flutes will be finish. After addressing each one of these considerations, the best style of chamfer for your job should be abundantly clear.
