Abstract
A cutting element configured to mitigate spalling on a front cutting face thereof. The cutting element include a diamond table having the front cutting face defined thereon and at least one recess defined on the front cutting face of the diamond table. The at least one recess has a width within a range of 25.0 μm to 650 μm and a depth within a range of 25.0 μm to 600 μm. Methods of forming a cutting element configured to mitigate spalling on the front cutting face thereof. The methods including forming at least one recess on a front cutting face of a diamond table to have a width within a range of 25.0 μm to 650 μm and a depth within a range of 25.0 μm to 600 μm. Method of using a cutting element configured to mitigate spalling on the front cutting face thereof.
