Are you struggling to choose between the Dremel 3000 vs 4000?  They are two of the most popular rotary tools in the professional woodworking world. They are finding their way onto the workbenches of skilled woodworkers and the tools of hobbyists around the world. Both the 3000 and 4000 have been selling well for years. Also, they have a wide range of accessories and attachments to choose from. The similarity between the two machines has led some people to argue that they are identical. Yet, others have said that the differences are so vast that it would be impossible to confuse one for the other.

Overview of the Dremel 3000

3000 Rotary Tool

The Dremel 3000 is an improved version of Dremel’s rotary tools. It is a hand-powered tool that has different tips used for craft purposes. It has the EZ Twist nose cap with a wrench that allows you to use the nose cap to function as a wrench. It tightens the parts of the rotary tool. You do not need a tool wrench when you have a nose cap. The fan design cools the rotary tool.

It comes with two vents that give a cooling effect to the tool when it is running. When the rotary tool is running, it heats hence the need for a cooling system. It does not affect your body. The symmetrical design has a nose cap that looks like a trumpet. 

You are allowed to use the accessories and attachments that come with the rotary tool. Its features make the rotary tool efficient. You combine them using a wide range of applications.

The case secures the accessories as they are not exposed to damage if dropped. The wrench fitment prevents your thumb and index fingers from being hurt. You are allowed to tighten and release the locking as you change the head accessories. It is inside the collar that fits comfortably. 

Use both the wrench and the collar to tighten the collet. However, you still experience sore fingers. That is why you need a separate spanner to switch attachments. The shell of the rotary tool has a 125W to 130W motor. That increases the torque, although the speed remains at 10,000 to 32,000 rotations per minute. 

The Dremel 300 is easy to handle and quiet. The ergonomic design makes it comfortable to use. The thumb grips take away the strain that comes with the tool. The shaft is flexible to use.
