Abstract
A cutting segment for stone and the like, the segment having a porous center section. A conventional mixture of cement and diamonds is made, and a quantity of filler is added to the mixture. The filler will withstand the sintering process, but subsequently falls out so pores are provided. A segment is made with only the center porous, while the side sections are as dense as is conventional. The result is that the porous section can receive coolant and/or the resulting slurry for efficient cutting, and the center section wears faster to yield a concave cutting edge.
