Let's get started!

It is potent enough for different surfaces but functions excellently on lumber. as pointed out, it generates reduced noise compared to other sanders within its range. The sound generated stands at 85 decibels.

Variable Speed

The Makita 9903 comes with variable speeds, unlike the Makita 9403 belt sander. Some belt sanders have a fixed speed, which isn't a big deal. You need to figure out whether you require this feature or not. 

For instance, if you usually work on one type of surface which calls for similar speed throughout, you won't need to purchase a power tool with variable speeds. On the other hand, if you`re like me and work on different surfaces that need varying speeds, then the Makita 9903 is the perfect companion. 

This unit offers adjustable speeds from 690 to 1440 ft/Min, and you can select your desired speed using the speed dial. 

Adjustable Belt 

Having a reliable and adjustable belt for your sander is vital. If the belt remains loose, the unit can significantly damage your workpiece. Fortunately, the Makita 9903 sports a feature that fixes the belt automatically, hence no more worries about damaging your workpiece. 

Dust Bag

Woodworking can be messy and dusty, which is why the Makita 9903 comes with a dust bag. This inclusion is advantageous since it removes all the dust and debris. Consequently, this leaves your lungs and eyes safe. 

Besides, the dust bag isn't inconveniently huge and has the ideal size for holding dust. Again, it's easily cleanable and aptly suitable for utilization in situations where sanded dust can be perilous. 


Like all Makita power tools, the Makita 9903 has a nice build, and even the position of the dust bag is strategic, as it lets the dust get in effortlessly without interfering with your work. 

This unit is equipped with a standard-sized 3 by 21 inches belt. Its build aids in flushing sand from the walls while the belt`s adjustment knob works efficiently to get the job done.

Comfy Handles 

Lastly, I`ll talk about the comfy handles featured in this unit. They are soft, easily holdable, and comfortable enough for working extended hours. The front grasp is ergonomic, making your work easier. The role of the handle is to direct the belt on the sanding surface; therefore, you need to consider it when shopping for a belt sander for the deck. 


The Makita 9903 belt sander comes with one belt and a dust bag for dust collection. 

Cost & Comparison

Regarding cost, the Makita is more on the expensive side at $260 to $300. However, with a 4.7 out of 5 stars rating, it's worth spending the extra funds to buy this beast. 

The Bosch OS50VC belt sander goes for $320 to $360, and it's the most expensive option in this review. On the other hand, the Triton T41200BS goes for $200 to $230. 


Bosch OS50VC Orbital Belt Sander 

Bosch has a reputation that precedes them, and with good reason. I honestly don't think this review would be complete without a Bosch product. 

The Bosch OS50VC will be a handy companion as you prepare your deck for staining and painting. It can effortlessly cover sections with not-so-wide spaces, no sharp corners, and a few edges. Besides, this sander will operate for a prolonged time without overheating or breaking down. 

The SheetLoc paper-clamping system facilitates fast unloading and loading of sandpapers. Further, its distinctive suspension system reduces vibration, allowing for stability. So, this unit is user-friendly, making it perfect for novices and professionals. 

The back and front lever mechanisms allow for easy removal and installation of different accessories, while the Velcro-like pad makes pulling the sheet much easier. That said, it is very expensive and unsuitable for use on wide surfaces.

Triton T41200BS Belt Sander 

The T41200BS belt sander has a handful of helpful features, such as variable speed control for improved adaptability and belt tracking modification for accurate sanding belt placement. Again, this unit comes with a higher material elimination and work rate due to the robust 1200W/10Ah motor and a 4 by 6 inches sanding surface. 

By connecting it to a steady workbench and utilizing the included accessories, you can swiftly turn this belt sander into an efficient bench-mounted sander.

When it comes to performance, the Triton T41200BS sander has a dust port at the back which connects to the dust bag, which comes with the device that links to a dust removal system for a safer and tidier workspace. 

The lock-on dial and rubber grip enhance ergonomics and control, particularly when working for extended periods. Also, it is user-friendly in terms of belt switch and stock elimination, with stock elimination being more reliant on the belts than the unit itself. 

This unit comes with a carrying case, inversion clamps, and replacement belts for utmost storage convenience. The Triton belt sander is an excellent companion for your mid-size and light tasks. 

Why Choose the Makita 9903 Belt Sander?

After intense research of the Makita 9903 sander, the specs, pros, and cons, I have concluded that this unit is the best belt sander for your deck. While expensive, it has multiple features that make it easy to use, reliable and efficient. 

When it comes to cons, there isn’t anything significant, just the price. Other power tools have disadvantages, but the Makita stands out and is a must-have for any serious woodworker.
