In between the minimum to maximum horsepower motor lies a great deal of options you can choose. When buying your next machine, make sure you choose the right motor size for your project.

Belt Speed

The best speed is essential for making high-quality knives or for best grinding results. That is why you should check this factor in every belt grinder you intend to buy. The speed is often measured in surface feet per minute SFPM. More SFPM is often considered better in a lot of ways.

If what you intend to use in your new belt grinder requires a slower speed, there is no need to go for a faster belt speed. However, in most cases, faster belt speed is better when any speed can be used. Therefore, find out before making a purchase what belt speed will be right for your projects.

Variable Speed

Choosing the right speed for each project can be a great strength to have in a belt grinder. Not all of these machines have the variable speed feature. Therefore, if you know various speed options would work the best for you and your grinding tasks, choose a sander that offers these features. You should also check the number of speed options it offers.

Faster speed completes the work quicker, and slow speed would take you so much time to c0omplete a knife. However, sometimes for you to do quality work, you will have to use both slow and high speeds at different times or different applications.

Ease of Assembly

You should check the cleaning method before you choose to buy any of these machines. Cleaning up may seem to be a small factor, but it is worth considering every bit.


It is all about how much money you are willing to part with to get a new belt grinder. It is a question every potential buyer should ask themselves before making the purchase. Once you have prepared a budget, purchase a machine whose price falls within that budget.

Different models come at different prices, and it is such a variance in prices that can help you choose what you can afford. If you know how much you are willing to spend on a new grinding machine, you will less likely be confused or find yourself in a dilemma.

Different Belt Grinder Size

It does not matter what you want to use your belt grinder for: the right size can make a huge difference in making your work a success. Whether you are in the knife-making business or just do it as a hobby, you should know how to choose your belt grinders.

If you are looking for a belt grinder for knife-making, the model you choose should help you create a sleek, beautiful blade. There are numerous machines to choose from, with some being better-suited to certain processes than others.

2×72 Belt Grinders

This size is best suited for professional knife-making and accounts for most belt grinders for knife making. You can never go wrong in creating the sleekest and most beautiful blade with this if you know how to use it and make knives. They are the industry standard and are compatible with several belt materials.

For their level of performance, the 2×72 belt grinders are surprisingly compact. These machines also come with more accessories such as wheel attachments, rotary platen, and surface grinding attachments. The 72-inch belt length reduces heat build-up and wear.

1×30 Belt Grinders

This is the cheapest belt grinding machine to start knife making with, making it an affordable investment for hobbyists. They are great finishing tools that also work well for detail work and knife sharpening. These tools may not be anywhere near their high dollar counterparts but for what they are worth. They are fantastic and a great place to start.

The belt is 1-inch wide, which makes it adequate for profiling knives and grinding bevels. However, the belt is not wide enough to flatten off materials effectively, even though that is a downfall you can live with.

1×42 Belt Grinders

In terms of performance, the 1×42 belt grinders are somehow similar to their 1×30 counterparts. As you can see, these machines have slightly more surface area for grinding, which is a good thing for your projects.

 However, it has a smaller range of abrasives readily available for it. The belts perform excellently for knife sharpening and detail work. You can use the 1×42 belt grinders for bevel grinding, profiling, and the greater part of the knife development’s initials steps. Also, remember that its smaller work surface and lower motor power make it inferior at creating knives faster.

2×42 Belt Grinders

These grinding machines are usually designed for the woodworking market. They often come with a six-inch disc sander on the side. They are always the better option than the 1×42 belt sanders since the two are similarly priced, but the 2×42 has a wider belt.

That makes their wider belts the winning point in the comparison between the two. They also work fairly well for knife-making and are popular with knife-making hobbyists. So if you are beginning and need an entry-level belt grinder, consider taking this over the 1×30 and 1×42 belts because it is more stable than these two.

2×48 Belt Grinders 

These grinders are very interesting in many ways. For instance, the smallest size of the belt can come in a square wheel configuration body. However, most commercially available grinders of this size are available in an upright style.

They also have an excellent array of belts, which is the same selection that is available for the 2×72. Therefore, the 2×48 machines can be an excellent alternative to the 2×72 grinders. Both hobbyists and professionals use both sizes.

4×36 Belt Grinders

Besides the fact that they are common, these are the sanders many people have questions about. Many sites warn people against them. But why? Most hardware stores have these machines, but they are not good for knife making.

They are not well-suited for most knife-making applications. The way they are made does not allow for the use of the belt’s edge, and since this is an essential part of knife making, you cannot use it for these applications. However, other parts can be utilized just well. For instance, they are great for woodworking.
