Drafting Supplies & Tools
Finding quality drafting supplies gets harder every year. Most general retailers have scaled back or dropped these products entirely as the industry shifted to CAD. At Drafting Equipment Warehouse, we went the other direction.
Since 1994, DEW has been one of the few specialty sources dedicated entirely to the tools of technical drawing and design. Our team includes an industrial designer, a structural steel engineer, and a working artist; people who have actually used these tools in the field, not just sold them. When you call us with a question about lead grades, what size parallel bar you need, or which template works best for a specific application, you’re talking to someone who has been there.
We’ve been supplying architects, engineers, interior designers, construction professionals, and students nationwide since 2000 — and we’ve been doing it as a small, family-owned business the entire time. That means real product knowledge, honest recommendations, and no runaround.
What You’ll Find Here
- Drafting instruments — compasses, dividers, and precision drawing sets for accurate geometric construction
- Pencils, leads, and technical pens — from everyday layout pencils to technical pens and drawing ink for use on vellum and film
- Rulers, triangles, and measuring tools — the fundamentals of every clean, accurate drawing
- Templates and lettering guides — circles, ellipses, architectural symbols, and specialty shapes
- Erasers and erasing tools — including electric erasers and erasing shields for clean, precise corrections
- Markers and highlighters — layout markers, design markers, and technical highlighters for presentation work
- Tapes, adhesives, and cutting tools — for mounting, masking, and trimming with control and precision
- Supply storage and transport — keep your instruments organized, protected, and ready to work
Whether you’re a professional who never left the drawing board, a student learning the fundamentals before moving to CAD, or a designer who simply works better by hand — you’ll find what you need here, and someone who understands why you need it.
