Review: Drafting and drawing math set - It’s a nice set of drafting & drawing precision math set templates. Review: Premium drafting utensils that work very well. - These items are perfect for heavy use or for occasional use. They are thick stainless steel so they aren't flimsy. They also feature cork padding on the back which minimizes paper tears and makes them easier to pick up off of a flat surface. The included ruler is about 13" long, which is substantially longer than the other items. I would rather have a 6" - 8" ruler included so that these would fit nicely in a small case. I found a nice, thick stainless 7" ruler at the local hardware store to substitute for the longer ruler. ## Features - BUILT TO LAST - Made from heavy-duty stainless steel with cork backing, this protractor and compass set with beveled edges won't bend or warp with daily use.

Just draw a straight line (to the length you need) using a ruler or any straight edge. Next determine where you want your angle to begin. Your protractor has a small hole at the center of the flat side - set this hole at the place you want the angle to begin and align the outer ends of the protractor (zero and 180 degree) with your reference line. Make a mark (pen or pencil) at the center hole. If you go straight up from there you will see the 90 degree indication, make a second mark at that position. Next draw a straight line (with a ruler or the flat side of the protractor) from the center hole mark on your reference line up to the 90 degree indication. You now have a line exactly 90 degrees to your reference line. Need a 45 degree angle to the right...again determine your starting point (along your reference line) and mark it, then lay the protractor so the center hole is directly over that mark and the straight edge of the protractor is parallel to your reference line. Count 45 degrees up from the 180 degree position (or down from the 90 degree position) and mark the 45 degree position. Now draw a straight line from your starting point to the 45 degree position and you have a line to the right at 45 degrees from your baseline. The trick is to always use the center hole as a starting point (where the angle you need intersects your baseline (reference line), and you can't go wrong. Cheers. **Q: Does anyone know the thickness of these pieces...? Do they have a cork backing..?** A: The metal is about a 1/32" thick. They do have a cork baking and with that added they are 1/16". They are very strong you have to bend them pretty hard to get any flex in the pieces. **Q: Where is this set made? Thanks** A: Made in China **Q: Trae escala en cms** A: Solo la regla los cartabones son en pulgadas ## Customer Reviews ### ⭐⭐⭐⭐⭐ Drafting and drawing math set *by F***D on September 11, 2025* It’s a nice set of drafting & drawing precision math set templates. ### ⭐⭐⭐⭐⭐ Premium drafting utensils that work very well. *by N***E on November 7, 2023* These items are perfect for heavy use or for occasional use. They are thick stainless steel so they aren't flimsy. They also feature cork padding on the back which minimizes paper tears and makes them easier to pick up off of a flat surface.

Recommended! *by D***S on February 17, 2016* Pros: * Stainless steel, beautifully finished. * Thick enough not to easily bend, while being light enough. * Corners on the triangles are not sharp, and are slightly rounded. Great for school as it reduces chances of accidental injuries. * Cork backing is excellent quality, thin enough to keep the equipment nearly flush to the medium being drawn on, but thick enough to afford scratch protection to the media being drawn on, and also extend some slide prevention (depends on the media) * Markings appear to be etched and printed, not just surface printed. This will ensure that they will last a long time Caution: * Not a very compact size, so it won't fit as a replacement to the plastic ones in typical school kits. Great for higher school grades, and advanced studies. May be too large for younger students. Recommended with caution on the limitations! Make sure the size is acceptable to you before you buy (just look at the printed length in inches on all pieces) Thumbs up for quality!! ## Frequently Bought Together - Staedtler Stainless Steel Math Set with Ruler, 2 Triangles, Protractor, 4 piece, 566 32BK - Staedtler Comfort 2 Pc Metal Quick Setting 6" Compass Set, 552 01 - Staedtler 12-Inches Engineer Aluminum Triangular Scale (987M1834BK),Blue --- ## 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/1319652-stainless-steel-math-set-with-12in-ruler-2-triangle-set](https://www.desertcart.co.uk/products/1319652-stainless-steel-math-set-with-12in-ruler-2-triangle-set) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
