Dremel 409 Cut-Off Wheel, 15/16" (23.8 mm) Diameter, .025” (0.6mm) disc Thickness, Cutting Rotary Tool Accessory (36 Pieces)

These can be expensive and also hard to find. I looked in lots of stores as my supply depleted. These reinforced cut-off wheels are basically an inch in diameter and very thin which is beneficial in some situations and I like using them despite the fact they can break easily. The other cut-off wheels which are designed for use with an easy release mandrill are larger diameter and thicker. They come in handy as well, but are too big for some projects.

These cutting wheels are cheap and perform superbly when used as advised. ([...]) I currently use these to cut aluminum alloy metal ferrules as well as certain plastics, such as those that make up ice coolers. I've broken cutting wheels because I've gone against these tips. With any high-powered tools, caution and scrutiny are always a necessity, especially for obtaining high performance. I've copied the 'Tips' section for those who decide not to follow the link. Pros: - Does exactly the following: Ideal for cutting, grooving and trimming all kinds of metal. May also be used on other materials-including thin wood, plastics and ceramics. Cut-off wheels make it easy to cut bolts or screws or make slots in rusted or stripped bolts and screws for removal with a screwdriver. -Cheap Cons: -Fragile and can easily break when not used as advised. User Tips The cut-off wheel cuts only along its edge. Do not attempt to sand or cut curved holes with them. (I do this, but very carefully. Not recommended bc they do break if not carefully applied!) Secure objects to a stable surface while working. Hold the tool so that the wheel is at a perpendicular angle to the material being cut. Keep a light touch, as the wheel will break under too much pressure. If chattering occurs, increase speed. Plastics require very slow speeds, because they tend to melt at the contact point. Wood requires low speeds also, always experiment on a scrap first.

I had previously been using Dedeco cut off wheels and was satisfied with the quality however they were much more expensive than the Dremel. I read a bunch of reviews here that these cut-off wheels would easily crumble and fall apart. I decided to give them a try. Here are my results: 1) Just like the Dedeco they are brittle and you must handle them with care especially not to bump side to side 2) Don't over tighten the screw in the collet or you'll damage the wheel and it will more easily break 3) Use a steady hand(s) when cutting and avoid any side to side movement. Either wheel (Dedeco or Dremel) will break pretty easy if it receives side pressure 4) I used the Dremel to cut through heavy duty staples (3/16"). I was able to cut through about 8 staples before having to replace (I had to cut dozens and the results were pretty much consistent). I thought that was pretty impressive. It was also 20 degrees outside. I even had a few wheels grab the stable a bit and they still did not break but any sideways movement they would usually fall apart soon. 5) I also used these to cut through an M6 (metric - 6 mm or .24") stainless steel bolt. Stainless is really tough but I was able to cut through the bolt with just one cut off wheel (just barely one). Bottom line - if you hold steady (preferable two hands on the tool), avoid side to side motion, let the wheel do the cutting, don't exert too much pressure, and don't over tighten the collet screw these should work just fine for most small cutting operations. I only cut steel... not sure how it will perform with soft substances such as plastic etc. Soft substances could cause heating and gum up.

These are the thinnest rotary tool cutoff discs I could find. They work well! But be sure to wear eye protection. Push them too hard and they will break, sending pieces of the disc flying across the room.

Nice quality, fast shipping

Good product

Better than knock offs. Doesn't break as easily.

These are nice and cheap and work fine as long as you use them right. The thing you have to remember about a rotary tool is that speed is your cutting attribute, not pressure nor power of the rotary itself. Light pressure, letting the device do the work for you wins the day. The one thing that will kill you is when you put too much pressure on these things and they snap and go crazy. If you are wearing a shield (and you should be) this is no issue. The thing that will hack you off is having to take the screw out of the end and getting another wheel. This will normally happen in tight spaces where control of the tool is difficult. As soon as you hit a weird angle or you are unable to control the jumping action against the substrate, things break down. I buy them a lot when doing large build and will keep doing so.

Ich kann die schleifscheiben überall sehr gut gebrauchen!

たくさん入っていて安価です。 丁寧に扱わないと破損します。 削るときも強い力を加えてはいけません。 それでも、ちゃんと金属を切断することができます。 ドレメルをお持ちの方は是非購入すべき品です。

As Described.

Used these to cut out rusty fender seams from a 60 year old car. I thought I would use most of the 30 but they did the job really well and lasted.

yes they were what i expected , i just had no idea that they were coming from Japan but the service was superb
