Selecting The Best Chamfer Cutter Tip Geometry

A chamfer cutter, or even a chamfer mill, is found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are simple tools which might be employed for chamfering or beveling any area in a wide array of materials. There are many reasons to chamfer a part, including fluid flow and safety, to part aesthetics.


Because of the diversity of needs, tooling manufacturers offer a variety of angles and sizes of chamfer cutters, and also various kinds of chamfer cutter tip geometries. Harvey Tool, for instance, offers 21 different angles per side, starting from 15° to 80°, flute counts of 2 to 6, and shank diameters starting at 1/8” around One inch.

After locating a tool with all the exact angle they’re looking for, an individual might have to go with a certain chamfer cutter tip that might are perfect for their operation. Common forms of chamfer cutter tips include pointed, flat end, and end cutting. The next three forms of chamfer cutter tip styles, provided by Harvey Tool, each serve a unique purpose.

Three Kinds of Harvey Tool Chamfer Cutters

Type I: Pointed
This brand of chamfer cutter will be the only Harvey Tool option links into a sharp point. The pointed tip allows the cutter to perform in smaller grooves, slots, and holes, relative to another two kinds. This style also permits easier programming and touch-offs, since point can be easily located. It’s because tip that type of the cutter gets the longest period of cut (with the tool creating any finished point), in comparison to the flat end with the other types of chamfer cutters. With only a couple flute option, this is actually the most basic sort of a chamfer cutter available from Harvey Tool.

Type II: Flat End, Non-End Cutting
Type II chamfer cutters are very just like the type I style, but feature an end that’s ground into a flat, non-cutting tip. This flat “tip” removes the pointed part of the chamfer, the weakest section of the tool. For this reason alteration of tool geometry, it is given one more measurement for how much longer the tool will be whether it stumbled on a place. This measurement is known as “distance to theoretical sharp corner,” which assists with all the programming of the tool. The main benefit of the flat end from the cutter now provides for multiple flutes to exist for the tapered profile with the chamfer cutter. With increased 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 an additional benefit 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 and much more advanced type of the kind of II style. The kind III features a flat end tip with 2 flutes meeting at the center, creating a center cutting-capable sort of the kind II cutter. The middle cutting geometry with this cutter makes it possible to cut having its flat tip. This cutting allows the chamfer cutter to lightly cut into the top of an element for the bottom than it, as an alternative to leave material behind when cutting a chamfer. There are many situations where blending of a tapered wall and floor should be used, and this is where these chamfer cutters shine. The top diameter is also held into a tight tolerance, which significantly helps with programing it.

In summary, there might be many suitable cutters for a single job, and you will find many questions you need to ask before picking your ideal tool. Deciding on the best angle is dependant on ensuring that the angle about the chamfer cutter matches the angle for the part. You need to be aware of how the angles are called out, at the same time. Is 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 as well as the longer along cut, these days, interference with walls or fixtures must be considered. Flute count is dependant on material and finish. Softer materials have a tendency to want less flutes for better chip evacuation, while more flutes will help with finish. After addressing each one of these considerations, the right style of chamfer on your job needs to be abundantly clear.
