Capabilities and limits
These features are produced by drilling or cnc machining. Capability: 82/90 degree, depth +/-0.05 mm. Design rule worth copying onto the drawing: countersink diameter within 2.5x hole diameter.
Design guidance
Before sending the RFQ, check these against your drawing:
- Feature rule: countersink diameter within 2.5x hole diameter.
- Over-specification is the quiet budget killer: a 20/10 scratch-dig face costs roughly three times an 80/50 face, so grade each surface individually.
The full rules live in our tolerance design guide and holes and edges design guide.
Who orders this
The recurring buyers of glass with countersunk holes: ccd inspection equipment (CCD cover plates, reference grids, stage glass); oled packaging (cover lids, frit-seal frames, fill-port plates); laser systems (windows, beam splitters, debris shields).

Common questions
Do parts ship with inspection data?
Dimensional reports, surface certificates and material certs per melt are available; specify the level on the RFQ.
What is the design rule for countersunk holes?
Countersink diameter within 2.5x hole diameter.
Is there a minimum order for glass with countersunk holes?
No. Single prototypes are accepted, and pricing steps down at 10, 100 and 1,000 pieces.
How fast can prototypes ship?
Machined prototypes ship in 5 – 10 working days. Coated or bonded parts add 1 – 2 weeks depending on queue slots.
