The Parts of a Flex Shaft
Pressing on the foot pedal (similar to a sewing machine pedal) controls how fast the bits, burrs, discs, and brushes spin.
You can purchase the motor, flexible shaft, hand piece, and foot pedal all in one kit. Many kits also include various tool attachments. This is the ideal way to get started. After you have the basics, you can purchase additional attachments and even different hand pieces.
Flex Shaft Manufacturers
Foredom is one of the top manufacturers of flex shafts, kits, and attachments. It's the most commonly used flex shaft among bench jewelers. You can purchase the kits as well as individual pieces from the Foredom website. Amazon and Rio Grande also offer Foredom flex shaft kits.
Choose an SR motor, one of the most powerful ones which will go forward and in reverse. It operates at 1/6 horsepower at 18,000 rpms and 115 volts. Foredom measures their horsepower in maximum efficiency, not in maximum output (like Dremel). If Foredom measured in max output, their flex shaft's horsepower would be the equivalent of 1/4 horsepower. That's a big motor.
There are different hand pieces available for the flex shaft. The most popular and most versatile hand piece is the Foredom H.30. It can accommodate small and large attachments to perform light or heavy work. The Foredom H.20 is also a common choice, but it uses smaller attachments than the 30 and is geared towards lighter bench work.
The 9100 Fortiflex is Dremel's most powerful motor. It operates at 1/5 horsepower at 23,000 rpms.
Drill bits are used for drilling holes and piercing metal.
Burrs are used for cutting, carving, and setting gemstones.
