2×42 Belt Grinder vs 2×72 Belt Grinder

When comparing a two-inch belt grinder, the Jet 41002 has many advantages over other brands. If you’re looking for a cheaper model, the craftsman or Palmgren models won’t cut it. However, a 439-dollar Grizzly 2×72 belt grinder is more rigid and a better value. The Grizzly is a better choice for people who regularly grind expanded and conditioning wheels.

Jet BG-379-1

A Jet BG-379-1 2×42 bench belt grinder is a powerful tool that is easy to use and safe to use. It features a hinged top cover, advanced belt tracking, a vented and fixed front wheel, and JET’s exclusive Spark Arrester. The machine also features a two-year warranty. Its powerful motor allows it to grind steel with precision and power.

When choosing a belt grinder for knife making, be sure to consider the speed, belt size, and motor size. A faster belt will remove more material faster and may be necessary for professional-level work, but a slower belt will provide greater control and a smoother edge on your blades. However, if you are just starting with knife making, a slower speed will provide better results. Many direct-drive belt grinders offer variable speeds. If you need versatility, the variable-speed version is ideal.


Whether you need a large work area, wide belt width, or smaller workspace, a 2×42 or 2×72 belt grinder is the right choice for your needs. These models are both equipped with great accessory options and excellent belt selections. The smaller models are perfect for general purpose work, but 2×72 models are better suited for more extensive knife sharpening and profiling.

Both grinders are compatible with most types of blades and blade materials, but they are best suited for beginners.

Its swivel mechanism makes belt changes quick and easy, and it can be tilted from a vertical position to a horizontal one.


If you’re new to knife making, you may be wondering which of the two Happybuy 2X42 and 2X72 belt grinders is the right one for you. The two grinders are similar in terms of price, but they offer different features and capabilities. The W1843 features a wide variety of applications, including knife sharpening, buffing, and various woodworking uses. The J-4103 offers a precise angle for fast and even grinding. Its steel frame is welded at its joints, making it durable and reliable.

The 2×72’s abrasive machines offer more options, including wheel attachments that range from 1/4″ to 16″. These wheels are great for tight spots and fullering and profiling. There are also surface grinding attachments that work well with the 2×72. Slack belt rotary platens are also becoming more common in 2×72 grinders.

It also features dual-thumbscrew belt tracking adjustment locks for maximum belt security and a rubber-coated drive drum to help reduce belt slippage.

Jet J-4103

When comparing the two models, consider what they have in common and what they don’t. For example, the W1843 2X72 belt sander is excellent for knife sharpening and buffing. However, the Jet J-4103 belt grinder is superior in many ways, including high-speed flat and level grinding and precision machining. Despite its low price, this grinder does not sacrifice vital details. It also has two contact wheels, one is 1.5 inches wide and three inches long, and a large yoke setting for smooth, even grinding.

Among its features, the 2X72 belt grinder has variable speed options and is suitable for knife making. It has adjustable speed control and a frequency converter. A 2×72 belt grinder should also have variable speed settings and a frequency converter. While wood and steel grinding is similar in function and performance, a thinner belt will increase efficiency and reliability. It’s important to choose the right belt size for the material you’re grinding because the wrong one can affect the final look of your knife.


You can’t go wrong with the Palmgren 2×42 belt grinder if you want to produce high-quality knives. Its versatility makes it a great choice for various knife-making tasks, including surfacing, finishing, deburring, and sanding. The 2×42 belt grinder has a cost-effective price, but that doesn’t mean it sacrifices any features. It delivers excellent performance for knives, and it’s easy to see why it’s one of the best grinders in its class.

The two models have a similar price range, but the difference is in the amount of abrasive they accept. The 1×42 is ideal for general blade sharpening, while the 2×42 is better suited to knife making. Both models have adjustable speed, but the 2×72 offers a wider work surface. Compared to the 1×42, the 2×72 belt grinder has more surface area and is more versatile than the 1×42.
