Review: Dremel Circle Cutter - All Pluses but Two Caveats - This circle cutter is well made as all other Dremel products and does the job. However, remember that this is still a Dremel tool attachment and not a router. This means doing a rough cut of the circle first as you would with a router and increasing the depth gradually in multiple passes. Otherwise, the tool will chatter and may ruin your cut. What I also like about the tool is that it makes smaller circles or holes (since it can be tweaked to do both) which the Jasper circle cutters do not do. The method I used was to rough cut the circle inside the line, of course, using a jigsaw but leaving a 1" bar across the diameter to support the pin for the center of the circle. After cutting halfway into the MDF, I sawed out the support and finished the circle with my router and patterning bit. This worked very well. Good luck! Review: Works well and a must have if you need to cut a big cirlce with your dremel. - Made cutting the circle for a sub in my bronco rear side panel very easy and clean. Works great. ## Features - Makes circles from 3/4 In. -12 In.

However, remember that this is still a Dremel tool attachment and not a router. This means doing a rough cut of the circle first as you would with a router and increasing the depth gradually in multiple passes. Otherwise, the tool will chatter and may ruin your cut.

After cutting halfway into the MDF, I sawed out the support and finished the circle with my router and patterning bit. This worked very well. Good luck! ### ⭐⭐⭐⭐⭐ Works well and a must have if you need to cut a big cirlce with your dremel. *by S***P on September 23, 2025* Made cutting the circle for a sub in my bronco rear side panel very easy and clean. Works great. ### ⭐⭐⭐⭐ Nice attachment for rotary tool *by S***. on March 28, 2024* I used this with my Harbor freight rotary tool and it worked well so far. I used the edge guide for cutting a bridge slot for an acoustic guitar build. I will also be using this as a circle cutter for installing the rosette on my guitar. The one downside to this tool, is the inabillity to line up the bit by eye, as the base covers up the cutting bit, and cannot be seen when the bit is cutting or before it cuts. This makes it difficult to get it in the correct position for cutting. The cost of the product was very reasonalbe. ## 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/82360021-678-circle-cutter-and-straight-edge-guide-rotary-tool-attachment](https://www.desertcart.kg/products/82360021-678-circle-cutter-and-straight-edge-guide-rotary-tool-attachment) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-13*
