In the case of laser drilling, a single laser pulse with a comparatively high pulse energy generates the hole. In this way, many holes can be made very quickly.
This method is often used in drilling thin filters. During percussive drilling, the bore is produced by several successive laser pulses with a lower pulse duration and pulse energy.
This drilling method provides deeper and more precise holes than single-hole drilling. Percussive drilling allows hole diameters from 0.02 to 0.4 mm and drilling depths up to 10 mm. High-temperature materials such as hastelloy, tungsten, molybdenum and all types of precious and non-ferrous metals are suitable for laser drilling.
