3 Types of Discs

Electroplated discs consist of a metal disc with a layer of diamonds electroplated onto the surface. Our electroplated discs are double sided and have either a ring of diamond coating, or a slatted or saw edge surface. These discs don’t last as long as the multi-layered discs, but are extremely efficient for a lower initial cost.

Multi-layered sintered diamond discs are just that. Layer upon layer of diamonds create the approximately 2.3 mm sintered diamond circumference ring on these discs. The thickness varies according to the diameter of the disc ordered, and ranges from 1/10th mm to 3/10th mm. These are absolutely great instruments for final or thin cutting and they last longer than regular electro-plated discs. Black marking is a non-issue because there is no metal to strike your work.

Solid sintered diamond discs are traditional, hot pressed instruments. They are solid sintered all the way to the mandrel. They last an extremely long time and do just about everything you would want a disc to do, except for final separation or creating a very thin space. The normal thickness is about 3 ½ tenths of a millimeter, and are manufactured in a variety of diameters.
