Best Belt Grinders for Knife Making

The best belt grinders for knife making will help you achieve beautifully designed sharp knives. These machines are constructed to help you shape the metal and sharpen it, to achieve the best results.

Despite being called a belt grinder, most models on the market are also praised for their dual belt and disc grinding capability. 

Here's a list of Best Belt Grinders for Knife Making

They are suitable for countless applications and bring the versatility of two tools in one.

With many models on the market, the real question is which one to buy. What features to look for and how to select the best?

A hard question, but not one that is impossible to answer. If you want to know which are the best belt grinders for knife making, check out our top picks below. But first, check out what features to look for before buying.

How to Choose a Belt Grinder for Knife Making

Buying a belt grinder requires careful considerations of the machine’s capabilities compared to your needs. Among a handful of specs, these are the most important to look at.

1. Dual Grinding Capability

Knife making requires a belt grinder, but unless you’re only making knives, having a disc and a belt in one machine is a more versatile solution. Most belt grinders for knife making have a disc too, so finding the right model should be reasonably easy.

2. Speed

It is essential to check the motor’s capabilities and speed of the machine. If you need a belt grinder specifically for knife making, than one that has a lower rate could suffice. Metals, as most hard materials, require more moderate speeds. However, if you want to make a wooden handle, for example, pick a unit that can reach higher speeds too.

3. Table Tilting

Some parts are more comfortable to shape or sharpen in a position different than vertical. Pick a unit that has tilting capability to make sure you have all the freedom you need. Most belt grinders can tilt at least 45 degrees, but for genuinely unlimited versatility, we recommend those machines that can tilt at 90 degrees.

4. Dust Management

Grinding leaves a considerable amount of dust and debris that can not only spoil your work surface but can eventually get into the grinder, altering the capabilities of the motor. To keep everything under control, choose a machine with a dust port, ideally compatible with all vacuum cleaners.

5. Safety

Last but not least, consider safety. The belt grinder you like must be easy to operate and must come with an easily accessible on/off switch. An overload shutoff is another desirable safety feature, and so are the belt and disc guards. Remember that grinding of hardwood and metals is dangerous, so always take all necessary precautions to avoid potential accidents.
