Abstract: The present invention relates to a chassis for a downhole drilling tool. The chassis is positionable in a drill collar of a downhole tool and includes a first portion and a second portion. The first portion defines a passage for the flow of drilling fluid through the drill collar. The first portion is made of a high machinable material and has at least one cavity therein for housing instrumentation. The second portion is positioned about the first portion such that the first portion is isolated from the drilling fluid. The second portion is made of a high strength and/or an erosion resistant material. A HIP process may be used to metallurgically bond the materials together to from the chassis.
