Highest powered tool in its class

One of the great features of oscillating tool is its high performance. It can accomplish the most demanding and the toughest applications as it has a motor of 3.8 Amp. It operates at 120 volts. This tool comes with 3.2 degrees of oscillation. It’s the highest Amp rated tool among those tools that fall into the same range of price.

Quick-Lock Accessory Change Interface

Every manufacturer of oscillating multi-tools has made their own design to provide a quick way of changing blades and accessories. Dremel is no exception. They have developed the Quick-Lock system.

This Quick-Lock Change System lets the user change the accessories with a simple turn of a lever. You can do it safely and without using any kind of tools. So, finally you can use a wrench-free oscillating tool. The Dremel MM40-06 Multi-Max provides you with the quickest accessory-change system than other similar oscillating tools in the market. It gives you the opportunity to switch between a wide variety of accessories rapidly and easily. It allows you to finish your projects without any trouble.

Quick-Boost Feature

This is a wonderful feature that comes along with this tool. Generally, while using an oscillating tool, it becomes a challenge to cut through a tough material. As the tool goes through the material, slowly it tends to reduce its speed and the user has to apply more effort to help it cut through. If you have faced this type of situation with your oscillating tool previously, now its time for you to be happy as the Dremel Multi- Max mm40 is available with a quick-boost feature. It keeps up a constant speed throughout the toughest materials and applications. You can stay worry-free that your oscillating tool might slow down or get stopped in the middle of a tough job. This tool has brought an improved cutting speed. You can avail that speed by maximizing the angle of oscillation to 3.2 degrees. By setting it to 3.2 oscillation angle, you can get double cutting speed than other comparable tools.

Quick-hold Magnetic Flange System

This one is another important feature of this Dremel multi max. The Quick-hold magnetic flange holds the accessory in place and makes it easier and faster for you to change the accessories securely. It also saves your time and effort. The Quick-hold magnetic flange system is designed ergonomically so that the accessories stay in place without slipping while in use. So it accelerates the speed of your work as the accessories don’t get moved at all and you can also accomplish your tasks safely.

Variable Speed Dial

When you are working on a project and your tool doesn’t allow you to change the speed of cutting or scraping, it’s the most frustrating situation you face. It becomes very tiring when you have to work with a wide range of material. If you can’t set the speed of your tool, then for some material it can cut or scrape fast, but in case of other material it can take ages. However, Dremel multi max-3.8 gives you the privilege to regulate the speed according to what kind of material you want to work on. Thus, it also augments your performance. The variable speed dial can be adjusted from 2 to 10.

Separate on/off Switch

Another aspect of this Dremel tool is that it has a separate on/off switch. So, the tool can retain the speed setting that you last used. So, if you want to work at a different speed level, at first you must adjust the speed dial and then you switch on your machine again. Otherwise, the tool will start working from the previous point of speed level unless you change it. But it saves time when you want to work with the previous speed setting. You don’t have to reset the speed dial.

Corded Unit

This is a corded unit and has a 7-foot rubber-coated cord. This corded tool delivers consistent power.


The tool is supported by a limited warranty of two years.

Solution: As it’s a corded oscillating tool, electricity is the only power source for operating it. No other power option is there for this tool such as batteries. However, an advantage of a corded tool is that most of the places have electricity support and you can get a stable source of power. Nevertheless, if you are in search of a battery-powered tool, then this tool is not the one you are looking for.

Use of non-Dremel blades is not recommended

Using any other brand blades with this Dremel MM40-05 oscillating tool isn’t recommended.
