Abstract
A super hard polycrystalline construction is disclosed as comprising a body of super hard material having a first fraction of super hard grains in a matrix of a second fraction of super hard grains. The average grain size of the first fraction is between around 1.5 to around 10 times the average grain size of the second fraction and the first fraction comprises around 5 vol % to around 30 vol % of the grains of super hard material in the body.
