Questions & Answers
I used this bit to drill a 3/8-inch hole in an 18-gauge stainless steel sink for a water filter spout; it took a long time, but it got the job done. To make a hole for this bit to fit through, I first used a very small metal drill bit, and then I used the fluted side of this bit to make the hole larger after I went through the steel. I'd look through the Dremel woodworking accessories to see if you can find a suitable bit for tracing hardwoods.
Yes, but it will lose its competitive advantage in the long run. It, on the other hand, will last much longer than high-carbon steel.
If you take your time, it will go smoothly.
It came in a sealed plastic bag with the Dremel logo on it, as well as the words "Tungsten Carbide Cutter" written in English and two other languages.

DO NOT DREMEL. These will work in a Dremel, but they are not a true 9901 Dremel brand bit. A true 9901 Dremel bit is full length 1/8" diameter, whereas these taper down and break easily at the taper, giving them the appearance of a 9902 Dremel bit. They cut well, but their edges do not last as long as a 9901 bit. I'm suspicious of their origins because they came in pairs in a small ziplock bag with an adhesive sticker on them. There was no Dremel trade marked packaging, so it could have been a mislabeled package.
They arrive quickly and at a lower cost than I can get them at my local hardware store. These are some of my favorite moments. If you're not careful and don't know how to use them properly, they can easily break. When used on metal, these are designed to run at a faster speed. I cut stainless steel with them almost every day. They're really good at what they're doing. They're ideal for softer metals such as brass and aluminum, as well as plastics at lower speeds. It's just a fantastic piece in general. There are numerous applications for this item. Get the tungsten out if you're not sure. For me, they last a long time, and I'm a bit of a snob when it comes to bits. br>Just keep in mind that high speeds should be accompanied by light to moderate pressure. They will not let you down if you are not in a hurry. Any time I need new ones, I'll be ordering from here. I would strongly suggest it.
I needed to shape an opening in the end of a hand railing that I had drilled. I was slightly off center, and all I had to do was round over a little to get the peg in the right place. This bit was ideal for the task and completed it efficiently. It sliced through oak with ease. Job done.
These aren't Dremel 9901s, whatever they are. They mic out at 3/32" at the cutting head, compared to 1/8" from shaft to head on the 9901. In addition, one of the three I ordered has burn marks on the metal, implying that it has lost its temper. Finally, they are not packaged by Dremel. They are packaged in a clear plastic baggie with a sticky label. br>br>If you're just scrolling on the surface, these should suffice. If you're slotting, you won't be able to get the right size slot with these!.
On my classic 351 Windsor, I used this to unscrew a stripped rocker arm nut. To get into a confined space, I needed a tool. This carbide bit performed admirably. I slit the nut in half from two different directions. Given that rocker arm nuts are grade eight, I was blown away. They were completely obliterated by these carbide bits. Keep a firm grip on your dremel and don't go too deep. Vacuum away shavings frequently so you can see what you're doing.
This bit easily cuts through plastic and leaves a nice smooth edge behind. The plastic is not melted or left with a jagged edge. It will cut wood as well, but I wouldn't use it on steel. When I tried cutting sheet metal from a computer case with this bit, it chattered a lot and cut slowly. Cutting sheet metal harmed the bit's teeth, causing them to break off in pieces. Fortunately, I stopped while I was still ahead of schedule, and my bit can still be used with softer materials. I haven't tried cutting Al with it; I'm sure it would work fine, but I think I'll stick to cutting plastic and wood with it. When cutting, this bit kicks up a lot of fine dust particles, so use it outside with a dust mask or respirator to avoid inhaling them.
It completed the task at hand. I had a hardened Phillips driver bit that had broken off, and I needed this to grind away at the screw until I could remove the broken chunk of the bit. This, along with another Dremel tungsten carbide bit in a different shape, were used. This bit lasted longer than the other one I used, despite the fact that I didn't use it as much. When using one of these bits on hardened metals, remember that tungsten carbide is a hard but brittle material.
Cutting product that works well. It was exactly as described. When I read other reviews that said it was a knockoff, I was concerned. But this is unquestionably a Dremel product. Unfortunately it is made in China so I can not be 100% confident in the steel. The diameter, on the other hand, is precisely measured.
