Why a 2x72

Ask knife makers and fabricators and most will tell you to skip the small grinders and go straight to a 2x72. The 2 in. x 72 in. belt is the standard size, so belts are easy to find in every grit and abrasive, and the machines take a wide range of wheels, platens and attachments.

Fixed speed or variable speed

A fixed-speed grinder runs fast, which is great for stock removal. Variable speed (usually through a VFD) lets you slow down for finishing, heat-sensitive steel and polishing. If you do fine work on knives or tools, variable speed is worth it.

Contact wheel and platen

The contact wheel diameter sets the hollow grind radius. 8 in. and 10 in. wheels are common for knives. A flat platen gives you flat grinds and squaring. Small-wheel attachments and slack-belt work round out what one machine can do.

Power and mounting

Many 1.5 HP grinders run on 120V; larger motors and VFD setups may want 240V. Plan on a solid pedestal or bench and dust collection: grinding swarf gets everywhere.

Belts are a running cost

Ceramic belts cut fastest and last longest on steel. Keep a range of grits on hand. Each listing shows what's included and what you'll need to add.

Questions about 2x72 Belt Grinders

Is a 2x72 belt grinder worth it over a 1x30?
For regular knife making or shop grinding, yes. A 2x72 has more power, more belt surface and a huge range of belts and attachments. Most people who start on a 1x30 upgrade later.
Do I need a variable speed belt grinder?
For heavy stock removal, fixed speed works. For finishing, heat-sensitive steel and polishing, variable speed gives you much more control.
What contact wheel size is best for knife making?
8 in. and 10 in. wheels are the most common for hollow grinds. The wheel diameter sets the grind radius.
Do belt grinders run on 120V?
Many 1.5 HP grinders do. Larger motors and some VFD setups need 240V. The product page lists the motor voltage.
What belts should I buy?
Ceramic belts are the best value for steel because they cut fast and last. Keep coarse grits for shaping and finer grits for finishing.
