Abstract
A method for making drill bits includes sequentially moving a plurality of drill bits through a belt furnace, and moving the drill bits to a cooling station using an automated device after the drill bits have moved through the belt furnace. A continuous process for making core drill bits may also include placing a drill bit on a belt of a belt furnace, transporting the drill bit through the furnace using the belt, removing the drill bit from the belt using an automated process, and cooling the drill bit.
