The cutting element further includes a sleeve extending around a portion of a side surface of the superabrasive layer and a side surface of the substrate, wherein the sleeve exerts a radially compressive force on the superabrasive layer. ## Claims ### Claim 1 A cutting element for use in a drilling and/or milling bit, comprising: a substrate having an upper surface; a superabrasive layer overlying the upper surface of the substrate, wherein the superabrasive layer comprises an upper surface, a rear surface secured to the upper surface of the substrate, and a side surface extending between the upper surface and the rear surface of the superabrasive layer; and a sleeve in direct contact with and extending around at least a portion of the side surface of the superabrasive layer and of a side surface of the substrate, wherein the sleeve exerts a radially compressive force on the superabrasive layer greater than a radially compressive force on the substrate. ### Claim 2 (depends on 1) The cutting element of claim 1, wherein the sleeve extends over at least a portion of the upper surface of the superabrasive layer. ### Claim 3 (depends on 2) The cutting element of claim 2, wherein the sleeve extends over a majority of the upper surface of the superabrasive layer. ### Claim 4 (depends on 2) The cutting element of claim 2, wherein the sleeve extends over an entirety of the upper surface of the superabrasive layer. ### Claim 5 (depends on 2) The cutting element of claim 2, wherein a portion of the sleeve extending over the at least a portion of the upper surface of the superabrasive layer comprises a central opening therein, a portion of the upper surface of the superabrasive layer exposed within the central opening. ### Claim 6 (depends on 2) The cutting element of claim 2, wherein a portion of the sleeve extending over the at least a portion of the upper surface of the superabrasive layer comprises an opening therein such that at least a portion of the side surface of the superabrasive layer and at least a portion of the upper surface adjacent the side surface of the superabrasive layer is exposed. ### Claim 7 (depends on 2) The cutting element of claim 2, wherein the sleeve is in direct contact with the upper surface of the superabrasive layer. ### Claim 8 (depends on 2) The cutting element of claim 2, wherein the superabrasive layer comprises a chamfered surface between the upper surface and the side surface of the superabrasive layer extending at an angle relative to a longitudinal axis of the cutting element. ### Claim 9 (depends on 8) The cutting element of claim 8, wherein a material having a Mohs hardness less than a Mohs hardness of the superabrasive layer is disposed between an inner surface of the sleeve and the chamfered surface of the superabrasive layer. ### Claim 10 (depends on 2) The cutting element of claim 2, wherein a portion of the sleeve extending over the at least a portion of the upper surface of the superabrasive layer exerts an axially compressive force on the upper surface of the superabrasive layer. ### Claim 11 (depends on 1) The cutting element of claim 1, wherein the sleeve comprises a material different from each of the superabrasive layer and the substrate. ### Claim 12 (depends on 1) An earth-boring tool comprising a tool body and the cutting element of claim 1 coupled to the tool body. ### Claim 13 A cutting element for use in a drilling and/or milling bit, comprising: a substrate; a superabrasive layer over the substrate; and a sleeve in direct contact with and extending circumferentially about at least a portion of the superabrasive layer and of the substrate, wherein the sleeve exerts a compressive force on the superabrasive layer greater than a compressive force on the substrate. ### Claim 14 (depends on 13) The cutting element of claim 13, wherein the sleeve exerts a radially compressive force on a side surface of the superabrasive layer and on a side surface of the substrate. ### Claim 15 (depends on 13) The cutting element of claim 13, wherein the sleeve exerts an axially compressive force on the superabrasive layer. ### Claim 16 (depends on 15) The cutting element of claim 15, wherein the sleeve extends over at least a portion of an upper surface of the superabrasive layer. ### Claim 17 (depends on 13) The cutting element of claim 13, wherein the sleeve exerts a radially compressive force and an axially compressive force on the superabrasive layer. ### Claim 18 (depends on 17) The cutting element of claim 17, wherein: the superabrasive layer comprises a chamfered surface extending at an angle relative to a longitudinal axis of the cutting element between an upper surface and a side surface of the superabrasive layer; and the sleeve comprises a protrusion extending radially inward toward the longitudinal axis of the cutting element and overlying the chamfered surface of the superabrasive layer, the protrusion applying axially and radially compressive forces to the superabrasive layer. ### Claim 19 (depends on 13) The cutting element of claim 13, wherein an upper surface of the sleeve is co-planar with an upper surface of the superabrasive layer. ### Claim 20 (depends on 13) The cutting element of claim 13, further comprising an intermediate layer disposed between the superabrasive layer and the substrate, the intermediate layer exerting a radially compressive force on the superabrasive layer.
