Etoput10pcs CNC Router V Bits, 3 Edge Pyramid Engraving, 1/8" Shank CNC 3D Milling Cutter| 20/30/45/60/90 Degrees, 0.1mm Tip

Multiples of each size. Very nicely ground and extremely sharp. I used these in a mill to make a very fine pitch nylon gear for a gear motor.

Just what I needed for my cnc machine

I like these bits and the pack is a good overall starter set. HOWEVER, the bits themselves are quite short and cause complications when working with certain material thicknesses and plunges. Good price and value though.

I read another review for these that mentioned something about their bits leaving “fuzzy hairs” along their tool path and that it was a “waste of money”. But pay no attention to their ignorance and simply do your homework when it comes to feeds and speeds for your materials.Then, you’ll realize that there is a great value to be had in this particular set of v bits.I have been doing CNC work for about 9 years now, and up until about a year ago, I was doing mostly 2D cuts on sheet goods for sign fabrication. I’ve only recently got into v carving for more graphic-intensive purposes.Most of what I do can be done with a much larger 90-degree but that I can run at a faster feed rate and at a lower RPM, but I needed something for the finer details. That’s how I landed on this set, which I am pleased to have done.Since these are 1/8” shanks, just be sure to run them at a higher RPM. Start with a moderate feed rate for your application and tune it as necessary when you start cutting. Just remember that every CNC and spindle are different and will always produce varying results. So there are no “one size fits all” parameters with any given bit or end mill. You’ll have to spend time with your machine learning it’s limitations with different materials and variations of speeds and feeds for each bit you use.

Very fine
