Jewelry makers, woodworkers, and detail-oriented crafters - this silicone polishing pin set is about to become your new best friend! You get 15 pieces total with three of each five different grades: Brown X-Hard, Blue Hard, Black Medium, Red Fine, and Green X-Fine. That range means you can handle everything from aggressive cleaning to super fine polishing in hard-to-reach areas. The 3mm diameter is perfect for getting into tiny spaces that regular tools can't touch - think intricate jewelry details, small crevices in woodworking, or delicate metal parts. The included mini chuck mandrel makes switching between pins quick and easy - just pop one out and another in. What's really cool about silicone pins is how they work - at lower speeds they're flexible with a soft touch for subtle work, but crank up the speed and they become more aggressive for tougher jobs. Made in Germany, the quality is immediately noticeable - these aren't flimsy pins that wear out after a few uses. The recommended RPM range of 10,000 to 30,000 gives you plenty of flexibility depending on your project needs. Whether you're polishing precious metals, cleaning up 3D prints, working on model kits, or doing dental lab work, these pins give you that professional finish that makes all the difference. The assortment means you're always prepared for whatever level of polishing your project requires - from rough cleanup to mirror finishes!
