What is a sandwich saw blade segment? What are its advantages?

Compared with traditional diamond blades, sandwich diamond blades have obvious characteristics.

Multi saw blade diamond cutting segment,The structure of the diamond sheet welded with silver solder on the circular saw blade is like a "sandwich".

The layers of these 3 parts are tightly compressed by high temperature. These layers are double layers of high-hardness diamond with a softer metal layer in between.

Sandwich cutter head has m shape and conventional type.such as:stone block cutting diamond segments.The purpose of designing such structure "sandwich" diamond segment is to keep balance during the stone cutting and make sure the stone edge is not declining.

The operational principle is like this: the bilatere diamond layer is harder than the metal layer in the middle, when cutting the stone, these 2 layers receive little abrasion and then become sharp "knife", it brings easy cut-in.

M shape sandwich diamond cutting segment.The metal layer is a bit softer in the middle, it assists cutting, finally the blade will go in the ready routin and makes the cutting straight, the planeness of the slab and tile is greatly improved.
