Main Differences

For professional and personal use alike, the Dremel brand is one that has withstood time for hundreds of tool owners; their Dremel 4000 and Dremel 4300 rotary tools are no exception to this standard of excellence.

Regardless of whether you have previously owned a rotary tool or are looking to purchase your first one, it may not be clear initially which of these models is best.

When it comes to many of the tool basics, they are identical. To determine which is best, other features need to be taken into consideration.

To help you make the most informed choice, here are the main features of both models.

Attachment Style

The key differentiator between Dremel 4000 and Dremel 4300 is the way the various attachments are connected to the rotary tool.

For the Dremel 4000, the various pieces are attached via an EZ Twist nose cap that utilizes a collet lock. This design allows for fast attachment changes and ensures your attachments stay in place when your tool is in use.

The Dremel 4300 has a unique, three-jaw chuck design that allows for the user to change accessories without needing additional tools. It is equally durable compared to its collet-using counterpart, but this design makes it a better, easier way to change out tips.

Kit Options

However, the Dremel 4000 model has four different kits available for purchase (2/30, 3/34, 4/34, 6/50), while the Dremel 4300 model only has two (9/64 and 5/40).
