Embodiment Construction

[0018] The present disclosure generally relates to devices, systems and methods for reamer blocks and other expandable tool blocks. A reamer block may include one or more cutting elements. For example, a reamer block may include one or more rows of cutting elements. According to embodiments of the present disclosure, a reamer block may include a knife pocket holder coupled to a body of the reamer block. The knife pocket holder may include a plurality of knife pockets. Individual cutting elements can be inserted into the cutter pockets and the cutter pocket holders can be connected to the reamer body. In this way, a standard reamer body can be developed and individual cutter pocket holders designed according to the unique conditions of the wellbore and operator preference. This can reduce manufacturing costs, improve ease of inventory management, and allow customization of cutting element profiles and / or patterns.
