Questions & Answers

What end mill should I use to get a smooth finish?

You should contact the cutter manufacturers because they will need to know what material you are cutting before they can tell you the type of cutter, spindle speed, feed speed, depth per pass, and so on in order to answer this question.

Ideal for engraving on wood

5/5

I have a few rotary tools and enjoy carving with them, but the majority of burrs and cutters for them are lacking, so I decided to try carbide ball end mills. It was the best decision I've ever made in terms of these tools. End mills with four flutes and a small to very small diameter are my favorites. In comparison to what is commonly sold as rotary tool cutters, these cutters provide exceptional cut quality. These are razor-sharp, precise, and cut cleaner than anything else on the market. Of course, this isn't the intended use for these mills, which is unfortunate. Wood engravers worldwide would be much happier if more people were aware of these cutters. br>br>With these cutters, I've been able to draw detailed organic and geometric shapes and replicate them very cleanly, either freehand or with my Proxxon and a mini router base. Because these cutters don't try to wander too much, they have a high level of precision. These cutters are unique in the wood engraving/carving world because they have four sharp flutes and a round tip.

1" cutting length is fantastic, but it's also very delicate! If you want to get a high feed rate, don't go any deeper than half the width! Prepare to go very slowly if you want a deep cut! I don't mean this to be a bad thing, but it won't put up with mistakes and will easily snap off

5/5

If you keep an eye on your feed rate and depth, the cutter will be a breeze to use. Chip ejection is excellent, and the blade appears to be well-knit. br>br>With so few end mills this thin having such a long cutting length, this is one of those tools that you absolutely must have in your toolbox, but it also demands a lot of respect.

Not up to par with other brands

3/5

I used to do some light engraving on mild steel when I was younger. When compared to the OSG we were using, it didn't hold up as well, even though it was only doing about half the tool life at the same speeds and feeds. I don't think it's a good idea to try it.

I would advise anyone considering this to spend their money elsewhere and get a higher-quality item

3/5

After only a half-second of use, the device broke. I was able to chuck just the ball end of the broken off piece in my CNC after it broke. In less than a second, it was broken. I would advise anyone considering this to spend their money elsewhere and get a higher-quality item. This is a piece of garbage.

This bit is more than adequate for lighter weight woods such as plywood, but it did dull on harder woods

4/5

You get what you pay for, as with anything else, and this is no exception. For lighter weight woods like plywood, this bit is more than adequate, but for heavier woods, the bit dulled faster than I anticipated. I mill letters and numbers for reference on a Shapeoko v2 with an upgraded DeWalt DWP661 motor. However, as a hobbyist, I found this bit adequate for basic wood engraving. The bit removed all of the material from the area cleanly, and when combined with a vacuum attachment, the result was a very clean cut. Based on the price, I would buy it again for my lighter weight projects.
