Each of the plurality of blades includes a gauge having a length and an angle. The machined connection is configured to allow attachment of a plurality of machined rings to the plurality of blades. 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. The drill bit is configured to operate in different formations based on the gauge of each of the plurality of blades. The drilling tool is redesigned by removal or addition of one or more of the machined rings based at least in part on a modified length and a modified angle configured in view of a characteristic of the wellbore. ## Claims ### Claim 1 A drilling tool for drilling a wellbore in a formation, comprising: 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, wherein the drill bit is configured to operate in different formations based on the gauge of each of the plurality of blades, and wherein the drilling tool is redesigned by removal or addition of one or more of the plurality of machined rings based at least in part on a modified length and a modified angle configured in view of a characteristic of the wellbore. ### Claim 2 (depends on 1) The drilling tool of claim 1, comprising: a locking pin configured to secure the plurality of machined rings to the plurality of blades. ### Claim 3 (depends on 1) The drilling tool of claim 1, wherein the drill bit is a fixed-cutter bit. ### Claim 4 (depends on 1) The drilling tool of claim 1, wherein the characteristic of the wellbore is based at least in part on a formation depth. ### Claim 5 (depends on 1) The drilling tool of claim 1, wherein the characteristic of the wellbore is based at least in part on a formation hardness. ### Claim 6 (depends on 1) The drilling tool of claim 1, wherein the characteristic of the wellbore is based at least in part on a rotary steerable system (RSS) employed. ### Claim 7 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. ### Claim 8 (depends on 7) The method of claim 7, wherein designing the drilling tool further comprises: securing the plurality of machined rings to the plurality of blades via a locking pin. ### Claim 9 (depends on 7) The method of claim 7, wherein the characteristic of the wellbore is based at least in part on a rotary steerable system (RSS) employed. ### Claim 10 (depends on 7) The method of claim 7, wherein the operational need is based at least in part on a formation depth. ### Claim 11 (depends on 10) The method of claim 10, wherein the characteristic of the wellbore is based at least in part on the formation depth. ### Claim 12 (depends on 7) The method of claim 7, wherein the characteristic of the wellbore is based at least in part on a formation hardness. ### Claim 13 (depends on 12) The method of claim 12, wherein the operational need is based at least in part on the formation hardness. ### Claim 14 (depends on 7) The method of claim 7, wherein the drill bit is a fixed-cutter bit.
