88 %

I think Makita 9403 4" x 24" Belt Sander with Cloth Dust Bag is a great tool not only for professionals, woodworkers or construction men, but also for other people out there as simple as me. Despite the fact that it was manufactured by a reliable company, Makita, I think it is such because of its great performance, power, efficiency and its usefulness to people who want to fix things on their own and save thousands (like me!).

Because of that, I thought about writing this guide to help you look for a high-quality belt sander when shopping for one. Other than that, this guide will also enlist other products similar to Makita 9403 4" x 24" Belt Sander with Cloth Dust Bag that are worth trying. Check out this article and learn more about the features of this belt sander.

We Like

  • It is heavy duty and efficient
  • The cloth dust bag catches most sawdust
  • It can be easily repaired

We Don't Like

  • It is difficult to work on vertical surfaces or surfaces underneath
  • Continually plugs up and doesn’t fill the sawdust bag when using 50-60 grit belts in some occasions
  • The metal flap, where the belt slides over the wood, isn’t flat


Once you are born in a family where every penny, bill and check is important, products that are long-lasting, durable and efficient are always a must-have. Though the price of a product is also an important factor to check, I always buy stuffs that assure me of a long-term use, regardless of the tag. I admit that a tag showing a few dollars catches my eyes, and soon I bring them to the counter and pay for it, but somehow in the long run, I have learned that low-quality products, though they are sold at a lower price, will only serve its purpose for a short period of time.

Aside from that, when you live in a house where every room looks like it is about to crumble, a great tool is really helpful to fix and patch up some of the damaged parts of the house. How I wish we could afford Makita 9403 4" x 24" Belt Sander with Cloth Dust Bag; our deck boards were repaired by an expert at an expensive rate. We could have saved thousands when we had our very own belt sander and repaired our deck boards on our own.

Who Is It For?

A belt sander like Makita 9403 4" x 24" Belt Sander with Cloth Dust Bag is not only fit for construction workers or professionals; it’s also great for people who love to DIY and save money. This baby is a powerful workhorse; with 120 volts and 1200 watts, it performs well with heavy duty construction works.

If I were to buy a tool, I wouldn’t be looking for tools that would only serve for a single purpose. I would be looking for some tool that is multi-tasking, efficient, powerful, reliable and affordable, as much as possible. No product is perfect, but I think this belt sander from Makita is the product I’m looking for. It might allow me to remove paints and finishes, smooth surfaces and repair deck boards. In my opinion, I think it is reliable, making it worth every penny.

With a belt sander which would allow me to repair a variety of damages on my own, it doesn’t only spare me from the expensive charges of construction workers and professionals, it also keeps me active and fit since I do all the work and fuss all by myself.

Buyer's Guide

What Benefits and Features Should this Belt Sander Have?

Every belt sander is different from others in some way. Either it is their capabilities, size or power; all belt sanders serve their own purpose. Here are a few features and benefits you should check on a belt sander before you bring them home.

  • Requires Small Storage Area

You don’t want to see your belt sander just lying on plain sight, do you? We also don’t want to see it stuffed in a small cabinet where it doesn’t even fit. So, one factor you should consider is a belt sander’s size. The smaller it is then the better.

  • Sawdust Collection Ability

You’ll always be dealing with dusts when you use a belt sander. Dusts, scientifically speaking, are particulate matter that can be harmful to us once we unconsciously inhale it. So, it is important that you check if the belt sander is equipped with a sawdust collector or not.

  • Motor Speed

We all want to get the work done quickly, don’t we? Well, when purchasing for a belt sander, you may opt for a belt sander with a motor of multiple speeds or you may also opt for one with a single speed. But, of course, a multiple-speed belt sander is always a better option.
