Although I've never tried it, I doubt it, as it doesn't seem so difficult
Working on hard stones is not a good idea
a piece true. I have found them to be a little less than $1 each. When you are running a machine with a true rotational axis, the precision you expect and have invested in may dictate that the bit you use is much higher quality and guarantees zero run out (often in the $10+ range). In hard wood, though, you will never be able to obtain a 5 thousandth of an inch of accuracy. A bit like this is only as good as its fiber structure, which suggests it would only be useful as a few-centimeter piece. With metal, you can get there, but with wood, you will need a very high grit sandpaper after a certain point
We recommend that you cut these burrs at the following From 5000 to With a rotational speed between 20000 rpm and a material hardness of HRA65, they are usually very smooth.

My name carved into a piece of wood did so much damage to the burr that I have provided photos to show you how much I damaged it. My biggest problem ended up being that I never really used those cents since I was afraid I was going to waste The only bad thing is that I'm saving the tungsten for that one special project. I am, however, extremely disappointed in the quality, as tungsten can carve metal effortlessly. A complete failure in carving wood would be surprising to most people.
Buying these is not recommended if you are going to use them to cut The bit did not exert much energy when I broke three. It would be easy to forget the brand, but I never broke any bits in another set (cannot remember which ones). It was disappointing.
There are no fakes here. Overall, I've found it to be the best for the money. From what I am able to tell, they are made of 100% carbide. It is a lot heavier than steel and not very magnetic, which is a positive Despite my low carbon steel abilities, I am able to work medium and high carbon steel like butter. To make these (or any carbide burr) work, you have to know the speed at which they rotate. Harder is it when the pace is slower. When I use my Dremel up to 35,000 rpm, I will spin it all the way.
My dremel has been running smoothly with all the bits I've put in so far. The bits have completed the cut I needed so quickly that I thought I was just getting started when I was surprised to see the bit had already completed Be prepared to cut right through the metal if you cut too carelessly.
The burs purchased from this set are great for wood and plastic. I use them on both.
It has been a while since I carved on steel with them and there is no sign of wear. **I only gave them a rating of 3 since they aren't 1/8 inch thick. These slip right out of my Dremel 4200 that I use my 1/8" bits with all the time. These are a little bit Thanks to my old Moto-G, I have access to the Internet They will be held by a holding tool.
This was bought to remove an exhaust bolt that had broke off on an engine . I also had broken off the extractor on the bolt. I only had one purpose in mind for these, to remove this bolt. Their efforts paid off! With a variable speed Dremel tool, a little bit of patience, and a little bit of work It was hard to do with these little carbide cutters since they ate through the hardened steel slowly & The bolt was broken off in aluminum, so be careful not to damage it. They had to grind hard metal over time but in the end they succeeded. The job I did was not a problem with a piece of wood, as well as fiberglass. Neither of them dulled nor broke. Tools that are good.
wanted to grind through a 1/2inch bolt and did some research on tungsten and found out that it is quite strong, but it can easily break. Handling this bit properly is key to ensuring it doesn't shatter. The pieces left me for dead, but when I handled them improperly, I only managed to break two, and to my surprise, the pieces didn't wear out at all. In the end, I was able to finish the project (which was my last hope) and it was a success! My initial impression was that the bits would be smaller, but they turned out to be incredibly durable and wear-resistant.
