Quick answer: Glass With Blind Holes covers depth control +/-0.05 mm, flat or radiused bottom. Prototypes ship in 5-10 working days.
glass with blind holes – manufactured to drawing with documented tolerances, from single prototypes to production.
The numbers
| Feature | Blind Holes |
|---|---|
| Capability | depth control +/-0.05 mm, flat or radiused bottom |
| RFQ inputs | PDF/DXF/STEP drawing, quantity brackets, surface and edge spec |
Specification advice
The shop-floor rules that matter here:
- Feature rule: leave at least 30% of thickness under the bottom.
- 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.
For the complete framework, see the tolerance design guide and the holes and edges design guide.
Capabilities and limits
These features are produced by ultrasonic machining or cnc machining. Capability: depth control +/-0.05 mm, flat or radiused bottom. Design rule worth copying onto the drawing: leave at least 30% of thickness under the bottom.
Where these parts end up
The recurring buyers of glass with blind holes: microfluidic devices (chips, manifolds, via plates, bonded stacks); semiconductor equipment (view ports, wafer carriers, plasma rings, chamber windows); industrial displays (touch covers, gauge windows, printed bezels).

Frequently asked questions
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.
What files do you need for a quote?
A dimensioned PDF plus DXF or STEP geometry. If only a sketch exists, our drawing review service formalizes it before quoting.
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 blind holes?
Leave at least 30% of thickness under the bottom.
