Durston 1551 Round Bracelet Mandrel 15" (380mm) Long Eurotool Wooding demonstrates the fundamental diamondThe Durston 1551 Round Bracelet Mandrel is a professional grade forming tool crafted from hardened steel with a smooth, highly polished surface. Measuring 15" (380mm) long, this tapered round mandrel ranges from 1 3 8" (35mm) at the smallest diameter to 3" (75mm) at the largest, giving jewelers and metalsmiths a wide working range for shaping and sizing bracelets. The polished surface helps metal slide and form cleanly without marring finished pieces.
