This burr is amazing and powerful but check first if it fits your Dremel size. Mine fits in my drill luckily but not in my Dremel tool as the shaft is quite thick.

Ok, so this burr worked even better than I had hoped. I was carving into dense resin to try and reclaim a fudged piece and this tool made the job much easier! Very happy how it went through the materials and very controllable; as I thought the burrs might catch and grab a bit more. Nope! Great design. And it held up great with no visible dulling of the points/burrs.

This bit handled maple and red oak easily. The barbs got full of sawdust after an hour of use, but it was easily cleaned out with a quick wire brushing.

der Kugelfräser ist deutlich besser als ich erwartet habe, ich kenne die Produkte ja bereits und bin sehr zufrieden damit. diese Kugelfräser ist recht fein, trägt aber dennoch ordentlich material ab. ich würde ihn etwa mit korn 100-120 vergleichen. die kutzall werkzeuge sind wie dauerhaft scharfes schleifpapier! ich finde sie genial und liebe es damit zu arbeiten. wenn diese kugel verstopft kann man sie wunderbar mit einer messingdrahtbürste und pressluft wieder frei machen. ich werde sicherlich noch mehr von diesem hersteller kaufen. das Werkzeug ist zwar echt teuer, aber die Lebensdauer ist großartig. Preis - Leistung = Ausgezeichnet

The tool is rated for 12k rpm- I have a 1speed 13k angle grinder with 1/4 adaptor. Bear that in mind. I used it on a maple wooden bowl. There is a learning curve as the tool only effectively cuts smoothly in one direction- it shreds and has a very strong kickback with any other directional changes. A very gentle approach with an iron grip are required. I have used other ball grinders specifically for angle grinders and had an even worse experience. The kutzall can at least leave a semi-smooth surface after getting the hang of it.If you already have the correct tools to accept a 1/4 shank, hopefully you have a better experience. I also purchased the kutzall fine round cutter- those clog up almost instantly and if not caught in time will burn the wood.

good for free carving or other wood removal in tight places... used to remove wood surrounding snug around old copper pipe to replace with PVC, about only feasible options...dropped once 3' onto concrete floor not hard to see impact spot on ball but still in good shape

This is an amazing bit! I needed to drill little "cups" into a thick acrylic sheet and this was the only bit I could find that would help me achieve this task. It did the job perfectly and has held up in quality. It is just as "sharp" as it was with the first round of drilling. I also used it on wood with the same excellent results. It is extremely difficult to find this type of bit and I am extremely happy with the results and durability that it provided for a very reasonable cost!

I am genuinely surprised at the quality of this tool. I used it to grind out the hollow part of a spoon and it worked wonderfully. I did 2 spoons from the same maple board. One board I used the Saburr Tooth sphere coarse and the other I used this Kutzall coarse. I thought based on looks that the Saburr Tooth would do the better job, but actually the Kutzall performed better, both in the speed of material removal and ease of handling. I thought the Kutzall would clog with wood and require cleaning every few minutes, but the opposite was true, it never clogged. The Kutzall actually ground out the wood and it came out in a fine dust, while the Saburr Tooth cut out much larger pieces, but at a slower removal rate. The wood heats up with the Kutzall, but it doesn't burn, at least if you keep the tool moving. I also got the fin Kutzall for clean up and it works well too, just not as profoundly as the coarse Kutzall, which is to be expected. I'm glad I got these tools and wish now that I hadn't got the Saburr Tooth tools.I have a dedusting system and work with the project piece with the Foredom rotary tool right at a point of dedusting suction. I generate a lot of the dust and most of it is captured by the dedusting system, but not all, so be sure to wear a dust mask as well.
