The 4000 and 3000 share some similarities. But the main difference is the power and on/off switch, which is higher or added to the 4000. The 3000 on the other hand is smaller and more light weight than the 4000.
But the 4000 features a speed dial that is separated from the on/off switch and can dial up or down speed in approximately 1000 rpm increments. The benefit for any user is that when you find that "sweet-spot" for speed, they will be able to get back to that. The on/off switch on the 4000 also locks out the collet or shaft lock mechanism. That means when the tool is on, you cannot accidentally push or activate the collet locking mechanism and damage the tool. Further the 4000 has electronic feedback, which gives you that extra push, when doing tougher applications.
See the overview below for specs:
Yes! The tool has consumer replaceable motor brushes.
The bushes should last between 50 and 100 hours, depending on your application. A consistently more aggressive application could cause brushes to require more frequent changing. Our advice is to check the brushes every 30 hours. When the carbon piece is shorter than 1/8 then both brushes should be replaced. Keep in mind they will not wear identically. Not checking and replacing your brushes could cause damage to the tool. Once replaced, we recommend the tool be turned on with no load for 5 to 10 minutes to seat the brushes. The tool will run smoother with seated brushes.
- For the Dremel 3000 and 4300 you can order replaceable brushes in the sparepart section
- For the Dremel 4000, you can contact a local service center to replace them for you.
The 3000, 4000, 4300 tools will work with all accessories in our line that are suitable for use on a high speed rotary tool. Most of those will have a 3,2mm shank. Some (like smaller drill bits) will have smaller shanks. If you are not using a keyless chuck (sold separately) it is really important to use the alternative collet and collet nut we supplied. The collet supplied with this tool will work with accessories that are 3.2mm shank. If you require a collet that will work with a smaller shank accessory, they can be purchased separately (#481, #482, #483) or in a full set (#4485). Please use the collet that corresponds with the shank size of your chosen accessory.
It depends – the 3000 features variable speed on a click-and-set switch – when using this tool your speed selection is going to be more of a feel or a sound as you get comfortable using the tool. The speed chart in the owner's manual acts as a guideline for the speed settings of 2/4/6/8/10 on the tool. If you know your application could require more exacting speeds or power then we would encourage you to consider moving up to the 4000 or 4300. You can also consider the cordless tools for extra freedom, these model numbers are 8220 or Lite (also known as 7760).
No. The 4000 is designed to be a tool that will work as well for heavy duty applications as it does for the lighter duty uses.
There are reasons this could happen and some things you can do to prevent it. The vents on the cord end of the tool are air intake vents. Keep those open and unblocked. The vents on the front or nose end of the tool are output vents. The air that is running through the tool has to escape through those vents. You may actually hold the tool near those vents, but we discourage you from wrapping your hand around the tool in a way that would COVER those vents. If you're holding the tool like a pencil, consider the use of a Detailer's Grip so you have optimal control and airflow. You may also consider the Flex Shaft Attachment – it take the weight of the tool out of your hand completely. If you're holding the tool more like a golf club, move your hands back slightly so they're on the body of the tool, not over the vents. It's also important to consider what you're doing. For example, to complete a task like cutting, you may be running the tool at 35,000 rpm, contacting a material that gets hot easily – like metal, and there's a lot of heat being generated. Having full airflow through the tool is really important. If you find the tool is really warm when you go to turn it off, consider letting to run for a minute with no contact on the material. This will keep the air flowing through the tool without generating additional heat from the application.
FAQ | Rotary-Tools | Cordless
There is no fixed answer to this question. The runtime of a cordless tool depends on the battery type, the type of application (e.g. light polishing or heavy cutting) and the tool model (Lite or 8220). We have designed our tools in such a way that the average battery life of each tool is matched with the most frequent type of applications for each model.
Dremel batteries will last for hundreds of charges.
Stall protection is built into the tool to protect the motor and the battery from overheating in the event of a stall in the material.
The stall protection kicks in when you put too much pressure on the tool for too long or the bit becomes bound in the work piece, especially at high speeds. If this happens, the motor will stop. Simply remove the tool from the material. If the tool was stuck for more than five seconds, you will have to turn the tool off and then back on to re-start. If the stall was less time than that, the tool should begin spinning on its own when removed from the material. If you find you are continually stopping in the work piece, you may need to consider an alternative tool, accessory, or technique to accomplish what you are attempting to do with the tool. Keep in mind the tool is more prone to stall sensitivity when the battery is close to the end of the charge.
For tools with separate battery charger (not usb charger), like the one for the 8220:
Keep in mind if the charger detects the battery is fully charged, the indicator lights on the charger may cycle through quickly and it will look like your battery is not charging. To check that, take your tool back out of the charger, turn it on and see what color the fuel gauge light is. If it is green, you are good to go. The tool does not need any charging. On the charger itself, there is nothing that will light up. All of those signals will show up on the tool. When the battery terminals in the tool make contact with the charger, the tool will evaluate the state of the battery. If charging is necessary, so the battery can accept any charge at all, the blue lights on the tool that indicated speed will scroll while the tool is accepting a charge. If the battery is too hot or cold, the tool will not charge immediately, but will reevaluate and when the tool gets to the proper temperature, charging will begin.
For tools with a USB charger (like Lite (7760)):
While the tool is charging, you will see the indicator in the tool lightened up. Once this light is off, the battery is charged:
The high performance motor will allow the tool to maintain speed under load/in use. The feature is designed to bring the tool back to the selected speed when the accessory meets the material. This will really be most noticeable at the lower and mid-range speeds. It will be undetectable in high speed applications. It is important to consider technique when using any tool that works through speed instead of torque. A tool that works as a result of torque or force is different than a high speed rotary tool. The accessory should never be forced into the material consider a less aggressive more frequent pass and at the lower and mid-range speeds, the tool will adjust to come back up to the selected speed.
This tool will work with all accessories in our line that are suitable for use on a high speed rotary tool. Most of those will have a 1/8 shank. Some (like smaller drill bits) will have smaller shanks. If you are not using a keyless chuck (sold separately) it is really important to use the alternative collet and collet nut we supplied. The collet supplied with this tool will work with accessories that are 1/8 shank. If you require a collet that will work with a smaller shank accessory, they are available separately (#481, #482, #483) or in a full set (#4485). Please use the collet that corresponds with the shank size of your chosen accessory.
All of the Dremel High Speed Rotary Tool Attachments are compatible with the 8220 but you may experience reduced run times on the battery when using certain attachments.
The tool is cordless, so the greatest satisfaction as a user may occur when you are using the tool in a situation where using a corded tool simply is not possible, like sharpening a chain saw in the woods, or in your garden / hard to reach places with a cord. Cordless tools do provide a convenience that corded tools do not have, but they also have run time limits.
Three solid lights means the battery is fully charged and ready to go. Two lights indicates the battery has 50% of the remaining charge. One flashing light means the tool is about to turn off. Three flashing lights indicate the tool is too hot for use, let it cool down. Three side to side lights indicate the battery is too low to run at all. A recharge is necessary.
