Manufactured by Barranca Diamond Products, a wholly owned subsidiary of MK Diamond Products. Barranca's BD297 lapidary diamond blades are manufactured in the United States.

 They are made from mechanically notched carbon steel (1045) cores. As the outer circumference of the blade does all the cutting there is minimum side clearance abrasion. This minimizes marks on the cut material, premature segment wear, and core overheating. BD-297 notched rim blades are for use with oil coolants only.

The saw blades are bushed to the correct arbor size at the factory. Because of this they have to be ordered in - the normal time frame is approximately 21 days. 5/8" arbors can be bushed to 1/2", 1" arbors can be bushed to 3/4" or 5/8". Please request at time of order.
