This event exceeded my expectations with how well it was organized and the friendly, competent staff. After more than 1,000 shows under my belt, Metalwerx has achieved a very strong attendance and pleasant buying atmosphere.
Flex Shafts Demystified
About this course
Confused by the dizzying array of rotary burs, bits, and mandrels on the market? Ready to invest in a flexible shaft machine (or have an old one that needs some TLC), but don’t know where to start? In this essential skill-builder, we will cover all the flexible shaft machine basics, from choosing the right models of motor, handpiece, and rheostat to maintenance and choosing the right bit for the job at hand. Through a series of detailed demos and Kristin’s thorough handouts, students will gain a firm understanding of rotary bits, from drilling, cutting to grinding and polishing.
