There are numerous belt grinders available in the market and while many of them seem very similar, there are differences that can greatly alter the quality of your project and budget. We understand the frustration of choosing the best belt grinder for your projects and here are some of the criteria that we used in picking the best belt grinders for this review:
Price
Price isn’t the only factor that needs to be considered but sure is very essential when sampling out your best choice. A general rule of thumb is that the price needs to match the value of the product. To be sure, you can start by comparing your favorite picks online. However, you need to be careful since cheaper prices might sometimes mean a compromise on quality.
Quality of materials
Material quality is a fundamental factor that influences the versatility of a belt grinder. To evaluate a belt grinder’s durability and its capability to be used for a wide range of projects, we reviewed the quality of materials used to make it. This varied from plastic, metals, and sometimes both. For sturdy, durable, versatile, and lightweight tools, most manufacturers often prefer to use a combination of plastic and metal. We also kept an eye on the paint used to coat the surface as it prevents corrosion. Note that subpar paints rub off on your workpieces.
Versatility
Top-quality belt grinders are heavily drowned with the sheer vastness of belt grinders in the market. Picking out the best one often means that you can easily use it to adapt to various functions or activities for different DIY projects such as renovations, carpentry, landscape work, and much more. The belt grinders we have reviewed in this article are able to handle the versatility of multiple projects while still offering premium quality.
Longevity and warranty
As noted earlier, the quality of material used to make a belt grinder influences its longevity. Here, we evaluated belt grinders largely made of plastics and metals. Plastic belt grinders easily break when used in heavy-duty projects while their metallic counterparts tend to be more durable. From this review, we recommend that you go for belt grinders backed by a warranty of at least 1 year to ensure the manufacturer stands behind their product.
