The #10 is a slender hand piece with rotating lever action that releases and closes the collet for quick and easy changes. It requires lubrication after the first 2-3 months of continuous use. This hand piece is designed to be used only with 2.35mm (3/32") burs.
Foredom's #10 Hand piece measures 7-3/8" long x 3/4" diameter. Weighs 4.5 ounces.
With the addition of a Duplex spring, #10D is more flexible than the standard model. Used for very delicate work and when more precise control is needed. Recommended for experienced flex shaft users.
