View Top 7 Picks Reviews

1. Estore 2 x 72 Belt Grinder

Estore 2 x 72 Belt Grinder
  • Motor Power: 1.5HP, single phase;
  • Disc speed: 3450 RPM.

Love to make the first entry with an advanced Estore 2 x 72 belt grinder. The pure attraction is its thick steel D-plate of 3/8". Even the good enough counterpart to which the 8" flat platen and idler wheels are both connected. However, the drilled and tapped D-plate becomes the only way to get integrated with the axles, which moves 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 1.5-inches handle comes with 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 3450 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.

Disliked

  • No noticeable cons.

2. WKM 2" x 72" Belt Grinder with Flat Platen

WKM 2
  • Power source: electric-powered;
  • Disc speed: 2850 RPM;
  • Motor: 2HP, 220V.

Our next top handy pick is WKM 2 x 72 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. For cursor grit belts, even under 80 grits need not attach a delicate mod to its dust shield back.

More handy precise knives 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 72" 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 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 most. Another specific adjustable belt tensioning releases the belt jams, however, allowing more precise works. 

What we liked 

  • Easy assembly;
  • Inexpensive replacement belts;
  • Easy belt changing;
  • Powerful and quiet.

Disliked

  • No noticeable cons.

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 including 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
