TopSeiko has been passionate with Micro Machining in brittle materials such as ceramics, glasses, and refractory metals.

With our continuous effort to improve ourmicro-hole drilling capabilities, we can now drill holes as small as 10 micron in ceramics.

Moreover, grooves as small as 50 micron width can be machined in Technical Ceramic materials. Grooves can be straight or spiral.

Small Hole Drilling is a specialty of Top Seiko.

We make parts with multiple hole configuration such as gas dispersion plates requiring hundreds or even thousands of small diameter holes on daily basis.

What makes us special is that it's not only many holes but clean de-burred many holes!
