What Is Wheel Grit Diamond?

Wheel grit diamond consists of monocrystalline diamond grains used as individual cutting points in bonded and electroplated abrasive tools. During grinding, the exposed grains remove material while the diamond and bond wear at controlled rates.

More friable grades renew cutting edges readily, while tougher, blockier crystals provide greater grain stability and wheel life. The suitable grade therefore depends on the required balance between cutting action, form retention and surface finish.

Wheel grit diamond, diamond wheel grit and wheel-size diamond grit generally refer to the same synthetic diamond product family for grinding-wheel applications.

Cutting Action
Exposed Cutting Points
Diamond grains penetrate the workpiece and remove material.
Edge Renewal
Controlled Fracture
Worn grains fracture to expose fresh cutting edges.
Bond Interaction
Exposure & Retention
Grain strength and shape influence retention and wheel wear.
Grinding Balance
Cutting vs Wheel Life
Grade selection balances cutting action, finish and durability.

Wheel Grit Diamond vs Crushed & Sharp Diamond Grit

Both are HPHT monocrystalline diamond abrasives, but different manufacturing routes create different crystal shapes and grinding behavior.

Comparison of wheel grit diamond and crushed sharp diamond grit
Comparison Wheel Grit Diamond Crushed & Sharp Diamond Grit
Manufacturing Route Directly synthesized HPHT crystals, followed by mesh classification. Larger HPHT crystals are mechanically crushed and classified.
Crystal Structure More complete single-crystal structure. Fractured single-crystal particles with newly exposed surfaces.
Typical Morphology Semi-blocky, blocky or well-formed crystals, depending on grade. Irregular, angular and multi-edged particles.
Standard Mesh Range 50/60-400/500 mesh 60/70-400/500 mesh
Grinding Behavior Controlled balance of friability, stability and wheel life. Sharper cutting action and faster cutting-edge renewal.
Common Selection Form retention, dimensional control and stable wheel life. Free cutting, lower grinding force and faster material removal.

Selection note: Products with the same mesh size may perform differently. Select according to the bond system, workpiece, grinding stage, surface-finish requirement and target wheel life.

Wheel Grit Diamond Selection Guide

Match crystal strength and morphology to the grinding load, bond system and required wheel performance.

Wheel grit diamond selection guide based on grinding requirement, bond system, preferred crystal properties and performance focus
Grinding Requirement Typical Bond Direction Preferred GWD Properties Main Selection Focus
Lower-load, free-cutting grinding Resin bond Lower strength · Controlled fracture Cutting efficiency, lower grinding force and heat control
General-purpose grinding Resin or vitrified bond Balanced strength · Semi-blocky to blocky Stable removal rate, surface finish and wheel life
Precision and profile grinding Vitrified or metal bond High integrity · Controlled wear Dimensional accuracy, form retention and consistent wear
High-load or long-life grinding Metal bond or electroplated High strength · Blocky crystals Grain retention, wear resistance and extended tool life

Final grade selection also depends on mesh size, workpiece, diamond concentration and actual grinding conditions.

Wheel Grit Diamond FAQs

Common questions about GWD grades, mesh sizes and product selection.

What is wheel grit diamond?
Wheel grit diamond is HPHT monocrystalline diamond classified into mesh-size fractions for bonded and electroplated grinding tools.
How is wheel grit different from crushed diamond grit?
Wheel grit retains a more complete crystal structure. Crushed grit has more irregular, angular particles and sharper cutting edges.
What mesh sizes are available?
Crownkyn GWD grades are available from 50/60 to 400/500 mesh. Coarser sizes favor material removal, while finer sizes improve finish.
What information is needed to recommend a GWD grade?
Provide the bond system, workpiece, mesh size, grinding stage, required surface finish and expected wheel life.
Can wheel grit diamond be used for grinding steel?
Diamond is mainly used for carbide, ceramics, glass and other hard non-ferrous materials. CBN is generally preferred for steel.
