Method and apparatus of drill bit adjustable gauge system

A method for designing a drilling tool for a wellbore, comprising:

• selecting a drill bit design based at least in part on an operational need;
• forming the drilling tool based at least in part on the selection of drill bit design,
• wherein the drilling tool comprises:
• a drill bit comprising a plurality of blades,
• wherein each of the plurality of blades comprises a gauge having a length and an angle;
• a machined connection disposed on the drill bit,
• wherein the machined connection is configured to allow attachment of a plurality of machined rings to the plurality of blades,
• wherein the plurality of machined rings are configured to form the length and the angle of each gauge based on number and type of each machined ring attached, and
• wherein the drill bit is configured to operate in different formations based on the gauge of each of the plurality of blades;
• selecting the length of each gauge based on a characteristic of the wellbore;
• selecting the angle of each gauge based on the characteristic of the wellbore;
• attaching each of the plurality of machined rings based at least in part on the selection of the length and the selection of the angle;
• selecting a modified length of each gauge based on the characteristic of the wellbore;
• selecting a modified angle of each gauge based on the characteristic of the wellbore;
• and
• redesigning the drilling tool by removal or addition of one or more of the plurality of machined rings based at least in part on the modified length and the modified angle.
