Manufacturers and prices
The range of prices for carbide blades for metal is enormous; the main thing here is to decide for which tool and what metal you will cut and make a choice based on this. The cost of wheels for aluminum ranges from 1,000 to 4,000 rubles, for steel from 3,000 to 20,000 rubles. There are also a huge number of manufacturers. Each company that produces circular or miter saws necessarily produces consumables for them, or buys products from third-party manufacturers and sells them under its own brand. It should be taken into account that there is no single standard for the mounting holes of disks and it is beneficial for manufacturers to make them different so that their tools can be supplied with the same consumables.
It’s pointless to talk about which discs are better and I won’t list the brands of major manufacturers. I can tell you from my own experience that I have used HILTI and ATAKA discs; the former cut better, but they are also more expensive. Reading reviews on the Internet, I heard a lot of good things about disks manufactured by CMT orange tools. When choosing disks, pay attention to it.
Diamond cutting discs for engraver

So, continuing to acquire all sorts of different tools for a relatively recently acquired engraver (popularly, a Dremel), I continue to acquire all sorts of different attachments for this tool. We already have circular saws, and diamond cutting discs arrived not so long ago. This is what we will be talking about in today’s review.
The seller was chosen completely randomly; the main criterion during his selection was the cost of the goods. It took her about 3 weeks to get to my post office, which is not that long. Unfortunately, there was no full track for the parcel, so here you can only get acquainted with its movement across China. The set consists of 5 diamond blades and one mandrel. Also in the parcel there was a note of gratitude from the seller, asking him not to forget to leave him a positive review. Apparently, he's trying to raise the store's rating.
