Makita 9403 Belt Sander with Cloth Dust Bag Review

Makita is one of the big names when it comes to power tools, as evidenced by the capabilities of the Makita 9403 11 Amp Belt Sander with Cloth Dust Bag. To wit, the Makita 9403 is a powerful belt sander that can do flush sanding at walls and other vertical surfaces with its extended base. Meanwhile, its wide belt can remove material quickly in order to ensure a high production rate all throughout. Furthermore, for something so powerful, it’s one of the quietest belt sanders you could ever get your hands on, with a noise level of 84 decibels only. This 11-amp wonder even includes a dust bag and a belt size of 4 inches by 24 inches. That’s essentially what the Makita 9403 1 Belt Sander brings to the table.

A Quiet Yet Powerful Storm

In order to give that 84 decibel rating context, here’s how noise levels are rated. A pin drop is 10 decibels, a whisper is 30 decibels, and talking is 60 decibels. Meanwhile, passing diesel truck is 80 decibels and a food processor and average belt sander is 95 decibels. It’s impressive that the Makita 9403 Belt Sander was able to bring down its noise at around 84 decibels, making it louder than a passing truck but significantly quieter than other belt sanders, food processors, or even a lawn mower (which is around 90 decibels). It also has a low profile so that less gouging and more balance could be achieved. There’s also its amazing large front grip that’s ergonomically correct.

High-Grade Construction All Throughout

Speaking of its design and construction, the Makita 9403 features labyrinth construction that seals its motor and bearings from contamination and blockage from the sawdust or steel dust, which are collected instead on its handy cloth dust bag that’s put in a convenient location for uninterrupted operation all throughout. Furthermore, its dust bag features double insulation and the ability to swivel 360 degrees. It’s also designed, as mentioned, to do vertical surface flush sanding through its extended base. It also features lever control for easy belt changes, one sanding belt, and a replaceable ceramic wear plate. Speaking of the belt, it’s four inches wide and can handle speeds of up to 1,640 feet per minute to ensure fast material removal every time.

Makita 9403 Reviews 

I love this belt sander, and here’s why. Named the Makita 9403 Belt Sander with Cloth Dust Bag on its Amazon.com page, it’s the sander I depend on when removing large quantities of stock without worrying about gouging (since it even has anti-gouging features included). Everything is visible because the dust goes directly to the dust bag, plus it comes complete with a soft start feature, compactness, balanced heaviness, a motor that’s safeguarded from the debris, and a large belt capable at going high speeds without snapping. It’s also very quiet, as advertised.

Cons

Some Amazon.com customers aren’t impressed with the Makita 9403. One Amazonian user claims the sander doesn’t have a flat metal flap that the belt slides over, which has a tendency to leave dish marks all over the wood you’re sanding. He had to put in a 4-inch wide piece of cloth back granite over the flap to make it flat enough for his needs, ensuring that it smoothed things out nicely.

Conclusion 

Although the Makita 9403 Belt Sander isn’t perfect and has flaws in regards to its flatness (there are even Amazon.com complaints about its dust bag not collecting a lot of dust), it still ranks high in all other factors. It’s as quiet as advertised, it’s ergonomically designed to not tire out your wrist, and it’s powerful enough to remove large quantities of stock or smoothen out multiple planks of rough hardwood without its motor smoking and damaged by the end of your work.
