You could use a 1×42 belt grinder for bevel grinding, profiling, and most of the initial steps of knife development, but the lower motor power and smaller work surface associated with 1×42 grinders leaves the 2×72 grinders more equipped to create knives at a faster pace. In many cases, it’s better to go with a 2×42 belt grinder over a 1×42 grinder. A 2×72 grinder would work best with a motor that has at least 2hp. On the other hand, a 2×48 grinder can work well with a motor that provides 1.5hp, because the length of the belt is shorter.
“Motor size is another crucial consideration when looking for a 2×72 belt grinder. The motor size will directly influence the amount of power the grinder outputs for grinding your knives. As the belt size increases, so does the demand for motor power. Experts recommend 1HP for every inch of belt width at 72 inches in length. This means a 2×72” grinder will work optimally at around 2HP. You will also have to know about your knife steel type to get the correct motor size. Don’t forget that a 2×72 inch grinder will enable you to use a wider selection of belt types and grits compared to the 1×30-inch belt grinder for knife making. We hope that this guide has made it easy for you to choose the best 2 x 72 belt grinder that fits your knife making needs.
