If you have need for thousands of small holes (one micron and larger) drilled into 0.0625 stainless steel tubing or larger, Lenox Laser, Inc. has this and many other products readily available for you.
Of great interest to many, Lenox Laser has made precision microhole arrays with a density of 35,000 holes in a 0.25" diameter disc. Custom orders are a specialty because Lenox Laser can produce virtually any array pattern in virtually any shaped part in many materials.
