As technology demands precision and smaller tolerances, engineers are turning to Bird Precision micro-drilled inserts. Bird Precision offers laser drilled, wire lapped orifices that are burr-free, extremely round and sharp-edged. Bird Precision's synthetic sapphire or ruby orifices feature zero porosity, high temperature tolerance and wear resistance, and are almost chemically inert. Bird Precision orifices exhibit highly repeatable flows from 0.5 cc/min and offer the industry paradigm for strength and dependability. Bird Precision orifices are available in standard hole sizes ranging from 0.0004" to 0.081", with or without stainless steel micro screen filtration, in many standard design sizes.
