I'm a full time carpenter. I have 35 years of experience on a belt sander. A good belt sander can provide quick, smooth sanding in experienced hands, or provide more fuel for a wood stove in inexperienced hands. An important consideration when choosing a belt sander is: Who am I? Tool is used 90% of the time. This tool from Makita 3 x 24 (9920) is the best solution for these 90% usage criteria. Mostly I do the sanding of the solid piece before assembly as well as sanding the assembled work. A NOTICE. If you are using this tool to sand floors or other large surfaces, this is not a sander. Buy a suitable grinder. This grinder comes in three sizes (18), (21) and (24). 24 is the best choice as it has a large sole that makes flat grinding easier. The straps also last longer. Note. Makita also makes a similar 4 inch wide model in this style. The straps are approximately 40% larger for that extra inch. avoid it If you really need a 4 x 24, buy Makita's HD model. (11 amps) Good. Features of this sander include: 1) This belt sander runs very well 2) The 15 foot cord length is important as you don't always need an extension cord 3) Light enough to be operated with one hand if required. less tiring with prolonged use 4) The dust bag picks up dust fairly well 5) The power is enough for most jobs 6) Made in Japan which has higher quality standards than most Overall I think it's really the best belt grinders that are available on the market will give you years of production. With over 1000 hours of belt grinders of all brands under my belt, I have the experience to know what I'm talking about.
