Dremel 4000 vs. 4300 – What’s the Difference?

Dremel 4000 vs. 4300

For hobby or professional wood crafting, you need a rotary tool and some of the most popular ones in the market are the Dremel 4000 and 4300. These can also be used to craft metal, making them very versatile.

Rotary tools usually come into play after saw cutting and they help in carving, engraving, routing, etching and sand polishing. However, these two units do have some differences and to understand them, we need to look at their features first.

1. Speed and Power: The 4300 Has a Slight Edge

Speed and power usually go hand in hand. Though the two have the same speed range (5,000-35,000 RPM) with a variable speed setting, Dremel 4300 has a slightly higher power draw of 1.8 amps compared to 1.6 amps for the model 4000.

This makes it slightly more powerful, allowing you to cut smoothly through hard materials such as metal. However, the higher power draw may result in a slightly higher power bill, especially if used continuously for long periods.

It is important to note though that both models have electronic feedback control. This feature ensures the tool regains and retains the selected speed after making contact with the material to prevent stalling.

2. Accessories: The Dremel 4300 Wins   

Dremel’s 4000 is available in 4 kit options, which are 2/30, 3/34, 4/34 and 6/50. On the other hand, the 4300 is available in 2 kit options, which are 5/40 and 9/64.

Taking into consideration the largest option for each, the 4000 has 6 attachments and 50 accessories while the 4300 has 9 attachments and 64 accessories.

This is quite a big difference. The model 4000 only gives you a shaping platform attachment, a right-angle attachment, a detailer’s grip attachment, a line and circle cutter, a flexible shaft and a multipurpose cutting kit as attachments plus 50 assorted accessories.

Dremel’s 4300 adds on a garden tool sharpener, a sanding-and-grinding guide and a pivot light to what the 4000 comes with, plus 64 accessories. This makes it more versatile because you can do more with the extra attachments and accessories.

One notable addition is the pivot light, which is very handy as it helps to improve visibility. Some might argue that you can comfortably use external lamps to illuminate your working area and this is true.

However, as you tilt the tool to carve, cut or sand your workpiece, you will block some incoming light at some point and this will create shadows that will interfere with visibility.

That said, the LED attachment is installed very close to the tip and rotates for convenient use. It is battery powered and this allows you to light up your work area even after unplugging the tool.

All in all, Dremel’s 4300 gives you more value for money, making it a better choice.

3. Ease of Use: The Dremel 4300 Wins

One of the most notable differences between the Dremel 4000 and 4300 is the accessory change system. The older 4000 model is equipped with an EZ twist nose cap, which basically functions like a bolt and nut.

Though not difficult to use, this system is a bit cumbersome, especially if you have to switch tips multiple times for your project.

However, the 4300 model has a keyless 3-jaw chuck that allows for quick clamping and removal. This makes it ideal for working on complex projects that require different accessory bits.

4. Operation: The Dremel 4300 Runs Cooler and Quieter

Dremel’s 4300 features a completely redesigned airflow system that makes it run cooler and quieter than the model 4000.

It produces 85.4 decibels, which is equivalent to the noise produced in a city’s traffic while the 4000 produces 88.9 decibels, which is equivalent to a running bulldozer.

5. Cost:The Dremel 4000 is More Affordable

It goes without saying that most new models of any product line are always more expensive than the old ones, especially if they have certain feature upgrades.

In this case, the Dremel 4300 is the newer model and packs in some new features such as the 3-jaw keyless chuck, a redesigned airflow system, and more accessories. Therefore, it is costlier than the Dremer 4000.

That said, if you still want the 4300 and you are on a tight budget, you can buy the one with 5 attachments and 40 accessories, which is relatively affordable. After that, you can buy the remaining attachments and accessories as extras if you require them in your project.

Otherwise, get the affordable Dremer 4000, which still offers very solid performance.

6. Other Features: The Dremel 4000 Lighter and More Compact

Concerning size, Dremel’s 4300 is slightly longer than the model 4000 by a centimeter. It is also heavier by 2.5 oz. and this effect will most likely be felt during long periods of use.

Conclusion: Which One is Better?

It is quite clear that the Dremel 4300 is better than the model 4000 because it is easier to use and is more versatile. Though slightly more expensive, it is a solid investment that every craftsman should consider buying.
