SND840 Synthetic Diamond Powder With Medium Toughness and Thermal Stability

  1. Synthetic Industrial Diamond Powder

2.  Character of SND840 

SinoDiam SND840 is a medium quality synthetic industrial diamond powder with Complete shape of cubo-octahedron, medium toughness and thermal stability, good wear resistance.  

Applied for making most of the medium quality diamond blade, core bits, electroplate diamond tools 

for stone and concrete.

3. Saw Grit Diamond Size Specification

SND890 20/25-45/50 SND880 20/25-70/80 SND860 20/25-70/80

Regular shape with the great 

thermal stability. Applied for 

making the high quality pro 

blades, core drill bits and 

diamond wires

High toughness, complete 

shape with straight crystal 

edges, good color and 

transparency, high toughness 

and thermal stability. 

Application of diamond cutting, 

drilling and grinding on hard 

materials.

Medium to high toughness, 

Blocky crystal shape, medium 

to high transparency and 

impact resistance, with 

relatively high thermal stability. 

Applied for diamond sawing 

tools and geological tools.

SND840 20/25-70/80 SND830 20/25-70/80 SND820 20/25-70/80

Complete shape of 

cubo-octahedron, medium 

toughness and good wear 

resistance.  Applied for making 

most of the medium quality 

diamond blade, core bits, 

electroplate diamond tools 

for stone and concrete.

Low to Medium toughness, 

semi-blocky shape, low to 

medium transparency and 

impact resistance, low 

thermal stability. Applied 

for for making diamond 

blade or girnding wheels 

for general application.

Low toughness, comparatively 

regular shape, low transparency, 

low impact resistance and low 

thermal stability. Applied for 

making the diamond cutting 

and grinding tools with 

medium-low load.

4. Other Grade and Mesh Size Diamond
