Using the wrong supply can damage the unit and voids any warranty the equipment may have. Select your voltage option above, then confirm the notice below updates before purchase. Learn more

The Foredom C.EM table top dial speed control gives flex shaft users a hands-free alternative to a foot pedal — set your preferred RPM once with the hand dial, then use the motor's own switch to return to that exact speed every time. The solid-state design delivers continuously variable control from off to full speed, with no hunting or surging, so you can stay focused on the work rather than managing the motor.

Two voltage versions cover jewelers and metalsmiths worldwide: the C.EM-1 at 115 V for North American 110–120 V mains, and the C.EMH-2 at 230 V for international 220–240 V mains. The compact plastic housing — just 5" long × 5-3/4" wide × 2-5/8" high — sits securely on the bench without crowding your workspace, and a green indicator light confirms power is live at a glance.

Features

  • Table top solid-state speed control operated by a hand dial — no foot pedal required
  • Continuously variable speed range from Off to full speed
  • Green indicator light shows when power to the control is on
  • Set a speed once and use the motor's own switch to return to it reliably
  • Replaceable fuse protects internal electronics from power surges and overloads
  • Compact plastic housing sits securely on the bench with a minimal footprint

Customers praised this dial control for delivering consistent, steady RPMs, particularly useful with hammer attachments. One shopper noted "love the control over rpms - keeps me steady and easier on my body." However, one customer found RPM scaling non-linear at lower settings, requiring careful monitoring.

Dial top control

This is a convenient way to achieve a steady rpm, especially when used with the hammer handle with its rpm limitations. I tested the rpm at different settings. With the unit I got, the rpm is not linear with the settings. At 1/4 setting the rpm on mine is around 7K. At full it is the expected 18K. Thus, be careful at the lower setting to not exceed the rpm recommended for the hammer handle.

Love the bench top speed control ! So nice to keep a consistent speed, especially with the hammer handpiece.

What was I waiting for?

I have the Foredom SR motor the foot pedal is good but sometimes the rpm goes higher than you need. Purchased the hammer attachment and needed to bring the rpm down. I now also have the constant rpm for drills, burs and my new hammer attachment. Must say I use this way more than I thought I would. I'm really glad I finally made the purchase.
