【DESIGNED FOR DELICATE LEATHER EDGE WORK】 Created by passionate leathercrafters, this fine sanding set is specifically designed to handle softer, more delicate leathers—such as chrome-tanned leather, Napa leather, and soft top-grain hides—where control and finesse matter most. It delivers smooth, consistent edges that hand sanding often struggles to achieve. 【TWO LEVELS OF FINE GRIT FOR SMOOTHER RESULTS】 The set includes 3 blue rubber bits (equivalent to 600-grit) for light shaping and 3 yellow rubber bits (equivalent to 1000-grit) for ultra-fine polishing. This grit progression is ideal for finishing softer leathers without damaging the surface—especially when preparing for edge paint or final burnishing. 【OPTIMIZED FOR LOW-PRESSURE, HIGH-CONTROL SANDING】 These bits use a softer abrasive formula that minimizes the risk of overcutting delicate leather surfaces. They’re ideal for precision edge work on chrome-tanned leathers, calfskin, and other smooth, flexible materials—perfect for soft leather goods that require a clean and consistent finish. 【FITS ALL STANDARD ROTARY TOOLS】 Each bit has a standard 1/8" (3 mm) shank, compatible with most rotary tools like Dremel or Proxxon. For best results—especially when working with soft leathers—operate at 5,000–15,000 RPM, and always begin at a lower speed to avoid scuffing or overheating the material. 【ENGINEERED FOR STABILITY & LONG-TERM USE】These bits stay stable with minimal vibration, even at high speeds—ensuring smooth, consistent edge work. We use them daily ourselves, and in typical hobby use, they’ve proven to be long-lasting—even after months of regular work. What may seem like early wear is usually just compression of the rubber surface. For best results, use the right grit, avoid heavy pressure, and clean after use.
