Dremel is a well recognized and respected brand. I would also like to give a big thanks to Amazon. I actually did not expect to receive my package after they arrived late ( after business hours) on their 1st attempt. And we were closed the day of the 2nd attempt.

But, there are a few catches. First off, it is awkward to use. You have to be very careful to hold the Dremel perfectly vertical while using it. Secondly, there are great limits as to what it will cut. The bits included will only cut softer materials. Don't think you are going to whip out oak medallions with it. And the thickness of the material you can cut is also limited. About an 1/8th is practical, cutting 1/4 inch plywood is difficult if not impossible, even taking several passes. Thirdly you do have to drill a hole in the center of the circle you are cutting, if the middle of the circle is the part you want. Having said that, it does cut perfect circles in acceptable materials. It can cut a very small circle, down to about 3/4 inch! and as big as foot. I use it for modeling, and it cuts 1/16th inch plywood, and sheets of styrene, very easily. It did a fantastic job of making exact arches on the front of a model building. It also comes with an edge guide for cutting rabbit grooves for interlocking panels. So it has come in very handy on several projects I have used it on. But you do have to keep in mind it's limitations. A nice accessory for your Dremel, expanding what you can do with it. ## Frequently Bought Together - Dremel 678 - Circle Cutter and Straight Edge Guide Rotary Tool Attachment - Fits Dremel Models 4300, 4000, 3000 and 8220 - Dremel 565 Multi-Purpose Cutting Kit - Dremel 335-01 Rotary Tool Plunge Router Attachment, Compact & Lightweight for Light-Duty Routing Projects, Perfect for Woodworking & Inlay Work --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/82360021-678-circle-cutter-and-straight-edge-guide-rotary-tool-attachment](https://www.desertcart.co.uk/products/82360021-678-circle-cutter-and-straight-edge-guide-rotary-tool-attachment) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-11*
