Good connector for removable power cable?

[blawb]

Hi all - I just found an old dremel that has a non-detachable power cable. I'd like to but a break in the cable and add a connector so that I can easily detach the power cable for storage. Should be something sturdy, maybe with threads. Any recommendations?

Don't do it.

Why?

Connectors on cords that move around a lot do last long.
You can do it, but don't be surprised if the connector goes bad extremely fast. On 3d printers hot end connectors fail ALL. THE. DAMN. TIME. I hard wire them them right from the start these days. Cars have the same issue, that's why all those connectors are strapped down, double clipped and secured. Same for aircraft, you don't leave connectors dangling and flopping around. It doesn't matter how good that connector is, it will not stand up.

These are good points, but many people use power tools on simple extension cords all the time, and those are fairly rugged. Also, on that type of connection, the female side is more likely to fail, but is easy to replace. Plus, a connector for this really doesn't need to be certified for thousands of hours of fly-time or drive-time.

well if you really want to and your dremel is a low voltage model, a simple barrel jack would do, with a lot of strain relief so it can last more than a week of use, else the copper in the cable will fail right where is stop being supported. if it is the 110/220v versions, well, no do not do it, you will have to have a rather bulky connector that will make your life harder than needs be, or do but get a connector rated for the voltage you use, and up to your country's standards.

And they come unplugged all the time unless the part where the plug is sitting stationary/on the ground. They use the cord to get there roughly where they need to be, just like using your Dremel with an extension.

My guess is you don't want that connector down at the end of the cord you want it near the handle which is always moving. Otherwise just use an extension cord.

No, what you want is is to buy a Foredom

IEC C8 paired with a C7 cord.

Absolutely not meant to be on a moving cord.
These are built to go from a stationary wall, to a stationary power supply.

No one puts a connector on the end of a moving cord unless they have to, it's just bad engineering.

Commando plugs then, 'cause of the name.

Those look fantastic.
