Laser-Drilled Micro-Hole Filter Disc is used for controlling flow and holding back fine particles with discs laser-drilled with micron-sized holes in exact positions — for restrictors, nozzles and medical devices. Custom to drawing is the reference cited for it on drawings, datasheets and purchase orders.
What Custom to drawing Means for Laser-Drilled Micro-Hole Filter Disc
The dimensions in the table below are supplied to suit Custom to drawing. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.

Specifying Laser-Drilled Micro-Hole Filter Disc Beyond the Standard
- Hole diameter & tolerance: 20–100 µm holes held to about ±3–5 µm.
- Hole count & layout: From a single orifice to thousands, in any pattern.
- Thickness: 0.1–0.5 mm; thicker discs need tapered or stepped drilling.
When Laser-Drilled Micro-Hole Filter Disc Is Not the Right Choice
Not economical for large open-area filtration — etched or woven media are far cheaper per hole.
