We've developed these bits to solve the issue of quickly smoothing the ends of cut synthetic whalebones. We make these bits in-house. They feature a groove to hold the synthetic whalebone in place for easy sanding. These bits fit all common rotary tools such as Dremel brand.
One bit will last through many, many corsets. Save a ton of time on your next project!

*We recommend wearing a respirator, safety goggles, and ear protection when operating rotary tools. Use common sense for dust collection and ventilation.
