Lapidary Diamond Saw Blades

How to choose saw blades

Start with your saw's blade diameter and arbor (center hole) size, then choose the bond. Sintered blades carry diamond throughout the rim and last a long time, while electroplated blades cut fast but the diamond layer wears away. Thinner rims waste less material; sturdier rims suit heavy cutting.

Blades are meant to run wet, so keep the coolant topped up and feed the rock gently to avoid glazing the rim.
