Description
The Proxxon FBS 115/E Precision Rotary Tool (No. 38472) is the high-torque workhorse of the Proxxon Micromot system. At 100W with variable speed from 5,000 to 20,000 RPM, it delivers more power and control than standard rotary tools — making it the go-to choice for demanding applications in model making, jewelry, woodcarving, metalworking, and electronics work.
The integrated keyless chuck accepts shanks from 0.3 to 3.2mm (1/64" to 1/8"), so you can swap bits without a collet wrench. Pair it with the Drill Stand MB 200 or Tool Clamp No. 28410 for hands-free stationary use, or attach the Flexishaft 110/BF for flexible-reach work in tight spaces.
