Among all of the options within the product category of multi-purpose tools, one thing that I like the most is the Fein MultiMaster FMM 350QSL.

This model has also been given favorable ratings in many other reviews in the past, which is an assurance that it can deliver a high level of customer satisfaction.

If you have personal or professional projects that need to be done, there is a need to have the right set of tools that will allow you to complete the job successfully.

Fein has recently updated the model name designations. Now I am looking into the differences between the new FMT250QSL | FMM350QSL | AFMT12QSL | FSC500QSL | FSC500QSL | AFSC18QSL and other models.

In the absence of these tools, it will be impossible for you to accomplish the output that is anticipated.

In my case, I make sure that I have a reliable, professional tool set. Even if I am not into professional carpentry and am just a DIY enthusiast, I know the need for the right set of tools.

Why Chose An Oscillating Power Tool

An oscillating power tool is not a single purpose tool. Rather, it is deemed as a collection of multiple tools that make small repairs and fixing jobs super easy in everyday life.

A typical set of oscillating tools, like the Fein Multimaster Q350, includes blades of various shapes and purposes. From cutting wires to sawing wood, these sharp-edged oscillation tools are vital to increasing work efficiency for carpenters and household engineers.

The true power of the Fein oscillating tool lies in the fact that no other tools can do what Fein Multimaster can. This gives the Fein tool an undeniable significance in terms of usefulness and proves to be a valiant partner in shaping a builder’s dream into reality.

Without a proper oscillating power tool in your toolbox, sooner or later, you would have to call the local handyman every time any upgrade would be implemented around the house.

To save both money and time, get yourself the Fein Multimaster tool to patch your problems yourself.

Fein MultiMaster 350Q Features

The Fein Multimaster 250Q | 350Q professional oscillating toolset is filled with exceptional features that make it one of the best products for people who have purchased sanding and scraping kits that will be used for various home renovation and construction projects, such as in installing tiles on the floors or walls, among others.

  • The StarLock Mounting system allows changing blades in 3 seconds without additional tools
  • Quietest and least Vibration of all oscillating multitools
  • New powerful and quiet 350 Watt motor
  • German quality

Powerful motor

Among the wealth of features that are found in this product, one that I personally found to be good is its 350-watt motor, which can be attributed as the primary reason for its dominant performance, whether you are sanding, scraping, or cutting.

Electronic Speed Control

It also has an electronic speed control that will allow users to choose the setting that is most appropriate for the job.

QuickIn Rapid Clamping System

This toolset also has QuickIn Rapid Clamping System. The main benefit that is being delivered by such is that it will allow you to change the functions of the tools in a snap.

You will not have to slow down the work that is being done as you change from one function to another.

Blades and Accessories

The universal E-cut blade is another feature that makes this product a cut above others in the competitive landscape. This makes the toolset ideal for various base and flooring work.

This also makes the product work perfectly on a wide selection of materials, such as plastic, wood, and drywall.

Some items included in this toolset are sanding pads, sanding sheets, a dust extraction kit, a carbide rasp, a carbide blade, a scraper blade, and a segmented blade.

With all of these, you will be given the guarantee that you will have all the tools that you need for the renovation job.

User Reviews

In many reviews about this product, one thing that is often highlighted is the fact that it has an ergonomic design, which leads to the reduction of fatigue and discomfort associated with its use.

Because of its smart design, even if the tools are used for an extended period, there is no need to worry much about being tired

Based on my personal experience, as well as based on the opinions that have been shared by other people, another thing that makes this toolset an excellent choice is that it is durable.

Even after years, you do not have to buy a new one as it can still function as well as new.

Lastly, in many reviews about this product, it has been praised because it is complete with the tools that you will need for sanding, scraping, and cutting.

This means that there is no more need for you to look for any other tool when you have this set, as it can offer what is needed for you to get the renovation job done.

Fein MultiMaster Pros

Quality

The quality of the MultiMaster tool is excellent – there’s a great design, the result of combining good materials with painstaking manufacturing processes. Think back to those days when quality was king in tool manufacture, and you’ll have an idea of the excellence of this tool.

Perfect For Sanding And Flush-Cutting

Functionally, this oscillating tool is perfect for sanding and for flush-cutting, with absolutely no lack of power (remember these 350 watts?). You’ll save time using this tool versus any manual method, and even when compared to most other power tools.

Easy Attachment Replacement

Changing the attachments is quick and easy too – the quick-clamping lever pops open and closed, yet it still holds each and every accessory piece tightly and firmly. All the attachable accessories have an eight-edged pattern, allowing attachment adjustments in increments of 45 degrees.

Dust Extraction

Dust extraction is excellent – the device does a fine job pulling in the dust during any lengthy period of sanding. Use the tool to remove hardened grout like it was soft putty, or to cut tough-to-get-to nails – the tool slides and cuts under siding like butter.

Sanding

Sand with ease those window frames that you want to repaint – the profile kit for sanding, which uses rubber inserts to form the profile for the sanding surface, is much better than the one for Porter Cable (which had to be returned to the store because of poor performance).

Long Cord

The attached extension cord is 16 feet long! How many power tools do you own with an attached cord that long?

Fein MultiMaster Cons

Price

This multi-master oscillating tool costs a lot – be prepared to pay big for it. Also, the blades the MultiMaster tool uses are expensive to replace, each one costing more than you would expect – and these blades have a very short lifespan. One blade wore out the first time I tried to cut a 10p nail, and it didn’t even finish the cut.

Speed Controller Ergonomics

For an oscillating tool, the variable speed control is difficult to adjust, and the control is located in an awkward position at the back. It’s also hard to see the blade when the tool is running.

Construction of Case

The plastic carrying case is flimsy – its walls are not much thicker than a few sheets of paper, and it doesn’t fully open 180 degrees, only to 90 degrees.

Sandpaper Type

I like the sanding attachments, but the pads fit the cloth-backed sandpaper only (of which you get five small squares of each of the three different grits). Paper-backed sandpaper won’t attach, and it’s hard to find supplies of the cloth-backed variety.

Finishing Thoughts

Here’s a couple of thoughts that could make you go either way for this Fein Multi Master tool. Read them, and decide for yourself if it’s good or bad for you.

The Fein MultiMaster tool is heavy – it’s not a one-handed tool and must be guided with both hands.

You do need some hand strength when attaching accessories.

Here’s what I’d suggest if you buy this oscillating tool:

  • at first, use the MultiMaster tool only with the attachments in the set – buy other attachments after you’ve verified how the old attachments work and whether they last
  • score lines for cutting wood, using a chisel or razor blade – otherwise, vibration on the un-scored wood will ruin the piece
  • wear ear protection – it’s noisy
  • find and buy a metal case that fits the MultiMaster tool – be sure the case has lots of compartments.

Additional Items to Consider

If you are going to buy the MultiMaster 350Q SL tool from Fein, I suggest that you also purchase the Fein 63502113019 3-5/16-inch flush cut wood blade. With such, you will have something that will prove helpful if there is a need to cut softwood.

This will be a great addition to the tools you have to make it more flexible for other jobs you have to accomplish.

Conclusion

This Fein MultiMaster tool is VERY useful, especially if you’re doing renovations or remodeling.

I’d consider it a vital addition to any remodeler’s or contractor’s toolkit. But expect to buy more attachments as time passes and add hundreds of dollars worth of attachments for your starter kit.

Also, be prepared to spend in total what you paid for the tool when you buy replacement supplies (sandpaper, blades, etc.). But I will say this – the Multi-Master is a serious tool!
