Core drill bit and methods of forming the same

A core drill bit comprising an abrasive tip and a drill body, wherein the abrasive tip comprises:

• a longitudinal axis running a length of the core drill bit;
• a first region comprising abrasive particles contained within a first bond matrix, wherein the first region comprises an annular cross-section about the longitudinal axis of the core drill bit;
• and
• a second region comprising abrasive particles contained within a second bond matrix, wherein the second region comprises an annular cross-section about the longitudinal axis of the core drill bit,
• wherein the first region comprises at least one first abrasive characteristic selected from the group of a first bond matrix composition, a first bond matrix concentration, a first bond material composition, a first bond material content (vol %), a first infiltrant composition, a first infiltrant content (vol %), a first average abrasive particle size, a first abrasive particle concentration, a first type of pores, a first average pore size, a first pore size distribution, and a first porosity, a first filler composition, and a first filler concentration;
• wherein the second region comprises at least one second abrasive characteristic selected from the group of a second bond matrix composition, a second bond matrix concentration, a second bond material composition, a second bond material content (vol %), a second infiltrant composition, a second infiltrant content (vol %), a second average abrasive particle size, a second abrasive particle concentration, a second type of pores, a second average pore size, a second pore size distribution, a second porosity, a second filler composition, and a second filler concentration;
• wherein at least one first abrasive characteristic is different than at least one corresponding second abrasive characteristic;
• and
• wherein at least one of the first region and the second region has a Fast Fourier Transform value greater than 1.
