While we are talking, they may innovate a new one and be available right at your stores. We have done complete research on today’s topic from the overwhelming list of such belt grinders, including belts.

Taishi Multifunctional Electric Belt Sander with 2 x 82 Inches Polishing Grinding Belt

  • Motor Power: 2HP, 1.5 KW;
  • Power Source corded electric;
  • Flat Platen: 2.5″ × 2.5″ (big wheels) solid aluminum wheels;
  • Aluminum Contact Wheels: 2.5″ × 2″;
  • Disc speed: 2800 RPM.

Love to make the first entry with an advanced Taishi 2 x 82 belt grinder. The pure attraction is its thick steel. Even the good enough counterpart and idler wheels are both connected. However, the drilled and tapped D-plate becomes the only way to get integrated with the axles, which move the pieces in both forward and backward positions to grind bevels. 

No flimsy contraption by the iron-cast construction, added steel coating is a plus point while using the beast. As a result, it becomes handier while dealing with smaller objects, either to manage the sturdy knives. Whether to deal with belt changing, the model goes so simple and easy.

However, the ergonomic push-down handle comes with an almost square shape. Over a tension beam, it leads all by itself with the tracking wheels. The motor accelerates the strategy at a single pass and 2800 revolutions per minute disc speed.

No dust shield included, but instead of making a slight mod, after making ports, use trimming the bottom by Dremel before attaching a dust port.  

What we liked 

  • Heavy-duty knife-making tool;
  • Easy belt changing;
  • Powerful and quiet;
  • Good for beginners.


  • No noticeable cons.

  • Grit Type coarse;
  • Aluminum Flat Platen: 2.5 X 2.5″/6.35 x 6.35 cm (Big Wheels);
  • Motor: 2HP, 220V.

Our next top handy pick is Happybuy 2 x 82 inches belt grinder with a flat platen. However, this one we found the best for knife making, even for industrial production with pro-graded manufacturing power at 3 phases. Competing with similar models in almost all grinders and sanders categories, this has achieved its position as an ideal aftermarket reliable belt grinder. 

You may do tasks by wearing out the belt; that is nice. Even under 80 grits need not attach a delicate mod to its dust shield back for cursor grit belts.

More handy precise knife production, including a VFD 2.2kw inverter to control better with multi-speed. Also, the 2HP motor runs with less stress and is available in the box.

Though it accepts a 2″ x 82″ belt, it is not an impossible task to fit a lower-sized one, for instance, 2″ x 42″ in it. Its arm and integrated belt sander work table are specially arranged for any big or small knives. If you are busy but want an easy belt change, the machine will allow for this. As well, the precision belt tracking system will help the most. Another specific adjustable belt tensioning releases the belt jams, however, allowing more precise work. 

What we liked 

  • Easy assembly;
  • High-quality grinding;
  • All-steel construction;
  • High-speed copper motor;
  • Easy operation & variable speed.

  • Belt sander table: 6-3/4 x 9 in;
  • Belt speed: 3400 FPM;
  • Disc speed: 2500 RPM;
  • Disc table tilt: 45 degrees.

Aiming for a standard 2″ x 72″ belt grinder? Jet J-4103 is the one in this price-to-weight ratio class. As stated in the title, it is worth much and makes itself so special for its integrated square wheel. Something more is its wheel area, about 3″ X 2″ or 1-1/2″ X 2″. Such contact wheels are very promising to reach tight spaces for grinding a great variety of wood and metals. 

As well, its serrated contact wheels are useful for removing heavy stocks, either to snag a casting after cleaning the top. Even if you want, you can go ahead with this for multipurpose finishing. The speed and efficient finishing will never disappoint you at any cost.

Want more? How about the platen setting? We have experienced this function for level grinding over its precise flat surface at high speed. We could not align the belt because of not include a similar mechanism for the bottom roller. Though top alignment works well with the top rollers, it may not become a pain point for the pros. 

What we liked 

  • Square wheels;
  • Never will choke with extended usage;
  • Accept pressures;
  • Similar in size, powerful motor, and disc.


  • No belt is aligned for the bottom roller.

Palmgren 2″ x 42″ Benchtop Belt Grinder

  • Weight: 35 pounds;
  • Power source: electricity;
  • Belt sander table: 6-3/4 x 9 in;
  • Belt speed: 4400 FPM;
  • Disc speed: 3500 RPM;
  • Disc table tilt: 45 degrees;
  • Platen size: 2 3/8″ X 7 1/4″.

The Palmgren 2″ x 42″ is an incredibly versatile benchtop belt grinder. As well, it performs contour sanding, intricate part sanding, and dry sharpening too. Combining the 2-in by 42-in. belt grinder with a benchtop sander makes it an ideal machine for standing crowds. Also, polishing, finishing, deburring, and bevelling are available in this all-in-one type belt grinder.

The grinding belt and the 6″ wheel often tilt up to 45°. However, you can choose between vertical and horizontal angles for workpiece precision. This mechanism lets users, like us, choose between bevel angles, especially for knife-making.

Due to its idle roller guard and the common removable belt platen, regular contour sanding for plastic, ferrous, non-ferrous, and composite materials becomes a painless process whether cast iron construction ensures structural rigidity with an anti-vibration system.

Featuring a 3.5AMP motor is impressive though powered by electricity. However, such limited power intends 3500 revolutions per minute at a single phase.  

What we liked 

  • Tracking adjuster;
  • Tool-free knob for removing old belt;
  • Both horizontal and vertically positioned operating belt arms;
  • Best for beginners.


  • Thinner metal platen.

Jet J-41002 2 x 42 Bench Belt Grinder

  • Material: cast iron;
  • Power source: electricity;

  • Belt speed: 3100 FPM;
  • Disc speed: 3450 RPM;
  • Disc table tilt: 45 degrees.

The apt title is the Jet J-41002 belt grinder takes 2-inch belt sanding to an unmatched level by the previous popular options. Nothing to beat this benchtop beast from Jet. Best suited to those with tight budgets or pockets. A flex shaft lets users mount on to alternate as a carver or sander. In general, the turning as an abrasive sander performs in multi-functions instead of any cop saws, or jigsaws. 

Featuring the belt unit can remove extra materials from the pieces, whether many of the well-established models do not let users step on for finishing with themselves, even in the case of knives or other flat pattern tools productions. So, the overall combined steps can help you to reach smaller spaces with its integrated thinner belt.

How about handling odd blade shapes? The precision angle, a kind of pro-grade miter gauge, can lock and can measure blades from both left and right sides, up to 45 degrees. The overall dimension with an 8″ wheel presents itself larger in 2 x 42 Belt Grinders listing whether the 3100 FPM belt speed stands itself as one of the highest categories.

What we liked 

  • Simple setup;
  • Dust deflector and chute;
  • Removable platen;
  • Cam lock;
  • Perfect for heavy knives making; 
  • Rubber feet.


  • Steel base;
  • Bad runout.

BUCKTOOL BD4801 Bench Belt Sander

  • Weight: 43.5 pounds;
  • Power source: battery-powered;
  • Belt Size 4″x36″;
  • Belt speed: 2161 FPM;
  • Disc speed: 3450RPM;
  • Belt Grit 120#.

The 4″ belt grinder by 36-inches, BD4801 series for knife making, manufactured by Bucktool. Such an impressive tool can sharpen tools. Not only within a minute but on a flat plate that is available in stores. Working like a belt sander, move forward to shape various materials. 

The model also accepts any brand 1″ belts. For top-quality metal sanding, this addition makes itself no longer a big grinder, except for the 6″ white wheel. This brush wheel removes rust at 3450 RPM, by enabling you for safe mounting. 

Else, other full belt guards, including battery-powered tools, are breezy during operations in darkness. Major integrated fast belt tensioning system, tool-free belt changes, simple belt tracking knob, and dust port ensure safety. Even this most portable sander can make itself easy with wood, plastic, or any composite materials. You can direct it as a bolted-on to a sturdy top for detailed work if you wish.

While finishing, polishing, and deburring heavy metals, we had no fret about its longevity. Because heavy-duty construction always supports a power motor that supplies power even running under loads. 

What we liked 

  • High belt and wheel speed;
  • Pasted design sand disc paper;
  • Plunge line sharpening accessory;
  • The aluminum sanding belt dust outlet can prevent melting;
  • High portability with battery.


  • No cons.

Jet 708598K JSG-6CS Belt/Disc Sander

  • Weight: 196 pounds;
  • Power source: corded electric;
  • Belt sander table: 12-1/2-by-7-inch;
  • Belt speed: 2500 FPM;
  • Disc speed: 
  • Disc table tilt: 45 degrees, 25 degrees.

Jet 708598K JSG-6CS is a great wielding shop starter grinder we have used so far. Apart from the 2×42 and 2×72 belt grinders, this one appears with a 6″ x 48″ size unique belt with other counterparts. Beginner-friendly for those in welding shops. 

Comes with a strong 1.5HP motor and a 15-34″ idler roller from the middle to the tool reset distance. However, you need a 20AMP circuit for consistent results. 

Yeah, in the bottom, a door is available in the cabinet. Settles down its powerhouse for working on both wood and metal sanding and grinding, but depending on the belt grit. Its task-level with good results also depends on sanding belt/disc installation. 2 ground cast iron tables are available for such reasons with miter gauge slots. Even in that case, it has integrated positional stops at 90° and 45° for both sanding tables. 

This unit can work without vibrations with disc sandpaper, not the belt paper on the 12″ disc. Which may create too loud for longer jobs. Including a 4″ dust collector; we recommend safety wearings before going ahead with the sharp edges.

What we liked 

  • Backstop for horizontal mode;
  • Belt guard;
  • Ground cast iron tables;
  • Beginner-friendly;
  • For heavy-duty jobs;


  • Expensive;
  • No dust collector included.  

WEN 6502T with Cast Iron Base 4 x 36 Belt Sander

  • Motor Power: 4.3 Amp;
  • Disc speed: 3600 RPM.

It’s expensive gear, but useful. You can’t overload this thing as It’ll stop, trip its breaker, overheat, and generally throw a temper tantrum. So, take care to not put an excessive amount of pressure and keep a copy . 

With a 4.3 amp motor, the WEN Belt Disc Sander easily sands, polish, and removes all of the notched edges and splinters on your wood and lumber. The belt also tilts anywhere from 0-90 degrees to accommodate the requirements of your particular workpiece, while the heavy cast-iron base prevents vibrations.

If one makes proper use of this grinder, it’s going to last for years to come. I’ll recommend using the vertical position, and also, don’t use the wheel sander frequently.

What we liked

  • Good speed;
  • Quite;
  • Great for the price.


  • Part can’t be found;
  • Dumb adjustment.


2 x 42 vs 2 x 72 Belt Grinder?

By the overwhelming fame of 2″ x 72″ belt grinders or the 2″ by 42″ ones, why do these become unbeatable by other models, for instance, 1″ by 42″ belt grinders? Either these split from each other more? The answers lie in their constructions. As stated, over 85% of modern belt grinders take 2″ x 72″ belts. In that case, the second raised in your mind is correct. Else, the size-based is another economy opt-out fact.

The 2 x 72 belt grinders are 30% more expensive than 2″ by 42″ or 1-inches width ones. Why? Because of the triple made grinding surface area. Also, the high work table and platen are perfect for knife sharpening and more detailed works.

Should You Use a 2″ x 42″ or 2″ x 72″ Belt Grinder for Knife Making?

A very common question. Making their own knives for multipurpose utilization, for instance, livelihood, hobby, art, and more. Many of the grinding machines come with battery-power or an electric cord as the power source, limiting their smoothing capacity and portability.

Blade smithing, in that case, a traditional DIY task. However, instead of sharpening stones, people turn this skill into knife making by 2-inches or 1-inch popular belt grinders. So, if you want a quality knife that fits in your hand, you should shop for a 2″ x 72″ belt grinder for better service with proper sharpening edges. 

Is there a Difference Between a Sander and Grinder?

A belt sander or a belt grinder? Most of the reviews declare these same for some similar jobs at the same time. Though both acts as sanders differentiate from their basic speeds and attachments. Speaking about the speed, sanders are not good enough for metals. Belt grinders at 3500 to 8000 feet per minute speed and more than 3500 RPM can grind the metals, woods, plastics by the single pass. 

Angled grinders use sturdy wheels or discs that are available with several types, and purposes too. The alignment of these belts is quite easy.
