Celco 15cm Metal Ruler – Stainless Steel with Conversion & Tap Drill Tables

You've got a plastic ruler that bends, fades, and gives you a half-millimetre wobble every single time. Toss it. This Celco 15cm stainless steel ruler sits flat on the bench, stays true, and doesn't care how many times you drag it across a worktop. The back doubles as a quick-reference card: printed conversion table, tap drill table, and W.W. UNF table so you're not hunting through a handbook mid-job. Dressmaking, technical drawing, workshop marking — it handles all of it without warping. Priced at $1.76 RRP, it's the kind of small tool that just works. Add to cart and it's on your bench before the next class or shift
