The modular reamer can include a tubular body having a first end and a second end and an internal bore, the internal bore extending longitudinally through the tubular body from the first end to the second end. The tubular body has an external surface with an outer diameter with cutting elements extending from the tubular body beyond the outer diameter of the tubular body for engagement with a bore hole sidewall. Each of the first and second ends have a coupling for coupling engagement with a tubular string. ## Claims ### Claim 1 A modular reaming device incorporable into a tubular string comprising: a tubular body having a first end and a second end and an internal bore, the internal bore extending longitudinally through the tubular body from the first end to the second end, the tubular body having an external surface with an outer diameter; and cutting elements extending from the tubular body beyond the outer diameter of the tubular body for engagement with a bore hole sidewall, and wherein each of the first and second end have a coupling for coupling engagement with a tubular string. ### Claim 2 (depends on 1) The modular reaming device of claim 1, wherein the first and the second ends are both threaded. ### Claim 3 (depends on 1) The modular reaming device of claim 1, wherein the first and the second ends are both female threaded, whereby the modular reaming device serves as a collar. ### Claim 4 (depends on 1) The modular reaming device of claim 1, wherein the first end is female threaded, and the second end is male threaded. ### Claim 5 (depends on 1) The modular reaming device of claim 1, wherein the tubular body is selected from the group consisting of steel, metal, metal alloy, or mixtures thereof. ### Claim 6 (depends on 1) The modular reaming device of claim 1, wherein the tubular body is steel and is grade P110 or greater according to API 5CT. ### Claim 7 (depends on 1) The modular reaming device of claim 1, wherein the cutting elements are selected from the group consisting of metal, metal alloy, steel, composite or mixtures thereof. ### Claim 8 (depends on 1) The modular reaming device of claim 1, wherein the cutting elements are cladded, deposited, or brazed to the external surface of the tubular body. ### Claim 9 (depends on 1) The modular reaming device of claim 1, wherein the cutting elements are a plurality of blades disposed on the external surface of the tubular body extending along a longitudinal length of the tubular body. ### Claim 10 (depends on 9) The modular reaming device of claim 9, wherein the plurality of blades taper at each end. ### Claim 11 (depends on 9) The modular reaming device of claim 9, wherein the plurality of blades extend diagonally with respect to a longitudinal axis of the internal bore of the tubular body. ### Claim 12 A method of making a modular reaming device comprising: forming cutting elements on an external surface of a tubular body, the external surface having an outer diameter and the cutting elements extending beyond the outer diameter, the tubular body having an internal bore extending longitudinally through the tubular body from a first end to the second end of the tubular body; and forming a coupling on at least one of the first or second end of the tubular body for coupling engagement with a tubular string. ### Claim 13 (depends on 12) The method of claim 12, wherein the coupling is a threaded end. ### Claim 14 (depends on 12) The method of claim 12, wherein both the first end and second end is threaded. ### Claim 15 (depends on 12) The method claim 12, wherein the first end is female threaded, and the second end is male threaded. ### Claim 16 (depends on 12) The method of claim 12, further comprising coupling the modular reaming device to at least one of a casing or a drillpipe string. ### Claim 17 (depends on 12) The method of claim 12, further comprising coupling a first end to a first casing or drillpipe and coupling the second end to a second casing or drillpipe. ### Claim 18 (depends on 17) The method of claim 17, further comprising disposing the modular reaming device coupled to the first casing and second casing into a borehole. ### Claim 19 (depends on 1) The modular reaming device of claim 1, wherein the tubular body is selected from the group consisting of steel, metal, metal alloy, or mixtures thereof. ### Claim 20 A modular reaming system comprising: a tubular body having a first end and a second end and an internal bore, the internal bore extending longitudinally through the tubular body from the first end to the second end, the tubular body having an external surface with an outer diameter; and cutting elements extending from the tubular body beyond the outer diameter of the tubular body for engagement with a bore hole sidewall, and wherein each of the first and second end have a coupling for coupling engagement with a tubular string.
