Shopsmith Premium Shaper Cutters are perfect for crafting your own unique trim and decorative edges. Shapers also create decorative joinery for a variety of applications and projects. Shopsmith Shaper Cutters can be used with any shaper that accepts 1/2 Inch Bored Cutters. For your safety, we recommend these cutters always be used with a Shaper Fence when straight-line shaping.
