    Default 4 Types of End Mills to Make your Machining Process Easier

    Generally, there are four different kinds of end mills that are used in sync with the end-product desired. They are:
    Straight Flute
    As the name suggests, these end mills have ‘straight’ and basic flute and are best for general use. They are also widely popular for their good edge quality.
    Up-cut and Down-cut End Mills
    They are spiral tools that either carry the residue chips up and away from the designated area, hence giving it a somewhat rough finishing, or take them down for a smoother top finish.
    Ball-nose Mill
    Ball-nose mill has rounded tips that are ideal for 3D tooling as they produce some high quality carved surfaces.
    V-bit
    Generally used for carving a V-shaped depression in the material, v-bit end mill comes in two forms- 60° or 90° V-bit. The sharp tip of the tool is used to cut through the narrow paths whereas the wider bottom is used to create larger cuts. This tool is also ideal when one wants exceptionally sharp edges, unlike the other end mill tools.
    Pro tip: If you want even better finish for your material, go for end mills that are tipped with solid carbide.

    Thanks for the copy/paste. It's also not particularly accurate.

    Straight flute is NOT best for general use, spiral is almost always superior.
    Up spirals don't leave any rougher finish than down spirals

    I agree with Elan. It reads like it was taken out of a woodworking text about CNC routers.

    Given that all he does is post completely vague questions then never returns to the thread, I'm suspecting he's a bot or somehow trying to generate clicks somewhere...
