Dremel 400 XPR vs 4000 | How They Compare Head-To-Head

Features of the Dremel 400 XPR

The Dremel 400 XPR kit features a flex shaft, circle cutter, lawnmower, garden tool sharpener attachment, and storage case. Dremel 400 Series XPR rotary tool offers performance, precision, and control. This is needed to complete a range of projects of all Dremel rotary tools.

That is from work, home, or studio. The XPR attachments take advantage of the increased strength of the device’s unique motor design. It works well with Dremel attachments and accessories. A combination of high speed and performance does not compromise quality. It has almost every feature you want.

This kit features the new 400 Series XPR rotary tool, saw attachment for cutting in tight places. The planer is perfect for unsticking doors affected by humidity. A flex light attachment to light up the work area, and sharpeners for lawnmowers and garden tools.

It has many attachments that work great. It cut through wood and drywall for installing outlets in basements, and attachments saw through metal.

It’s a very high-quality rotary tool that comes with a foot pedal. The pedal is for speed adjustment, which makes a difference by making the work easier. The Dremel and the cable extension with some bits yield better results, and the variable-speed tool works very well.

It gets into small spaces, and with the variable speed, you have control while working on your project. The Dremel gets hot when running at high speed.

Speed variance

Variable speed provides great control and precision and varies from 5,000 to 35, 000rpm. That way, you have the freedom to match your material with speed.


It features a permanent magnet motor for increased performance and consistent speed at all speed settings. The Dremel motor gets the job done while maintaining a consistent level of speed and power.

Speed selector

The speed selector switch is in a different location than the power switch. You can easily keep track of the last speed you used, making it a snap to pick up where you left off.

Features of the Dremel 4000

Dremel 4000 is a rotary tool. It comes with 6 attachments, 50 high-quality Dremel accessories, a deluxe carrying case, and an accessory case. An effective ventilation system makes the workspace conducive. It prevents heat from building up. That is why the tool has managed to be noise-free and smooth.

The storage case protects your tool from damage. Dremel 4000 comes with electronic feedback control that signals when something is not working. That includes speed and too much pressure. If your grinding becomes too hard, you get a signal.

You have control over what happens with the rotary tool. Dremel 4000 introduces a speed dial feature that you easily turn on and off. You are allowed to change the speed even when you are operating the rotary tool without stopping it. That gives the rotary tool maximum performance.

Dremel 4000 comes with better attachments, although it allows some dust to get inside the rotary tool. I urge you to use compressed air to get rid of the particles. The rotary tool is solid and durable. In case of an accident, it does not break easily.

The tool combines practicality and technology, and the motor brings out maximum performance. There is a balance between power and ease of manipulation. The rotary tool is ideal for professionals, and it is user-friendly.

The rubber grip makes the operation comfortable. You hold the rotary tool in your way that makes you comfortable. You have no fear of having the tool slipping off your hands. Compatibility is one of the strengths of the rotary tool. It comes with more accessories that it works with.

The speed dial assists you in controlling and monitoring speed. The dial is in an area that does not disturb your operation. It is far from the handle. A separate On/Off switch makes the Dremel tool easy to use.


The motor is strong enough to deliver top performance at all speeds. The speed varies from 5,000 to 35,000 RPM. It consists of an electronic feedback circuitry with notifications when there is a fault or the rotary tool is at risk. That allows consistency in performance even on tough tasks.


Dremel 4000 has a slim and ergonomic body. The 360-degree grip zone gives you extra comfort, and that extends usage.

Which is better

The Dremel 400 xpr is the better version of Dremel. It is versatile and handy. However, it is less affordable than the Dremel 4000 due to its small size. It is a small tool that does almost everything. It is for all small hobby cutting/grinding tool needs. You can still make the same operations using the Dremel 4000.
