Saeshin AT-11 Jura Straight Nose Cone (End Handpiece Only)

Part # 134.495EX6B Only 2 left Weight -- lb -- g
Current price $120.00

The Saeshin AT-11 Jura Straight Nose Cone is a replacement end handpiece designed for use with JURA Micromotors. This straight nose cone was standard equipment on the first generation of JURA micromotors and remains a compatible replacement for those machines. JURA's newer machines use the NSK EX6B nose cone, which is only available through dental dealers. The Saeshin AT-11 is identical to the NSK EX6B in size, shape, and performance, making it the practical solution for jewelers and metalsmiths who need a direct substitute.

This is a slim, precision handpiece that accepts 2.35mm diameter burs only. Its slender profile is popular for detail work, though the narrow construction means it may require replacement sooner than thicker handpiece designs. Longevity depends entirely on how the handpiece is used and maintained.

This handpiece has no replacement parts and cannot be serviced by the owner.
