How small of a hole can you EDM?
The ultra precision discharge circuit for micro machining also contributed. Makino’s EDM Applications Department in Auburn Hills, Michigan, has produced holes as small as 0.0015 inch diameter in testing. Hole diameter tolerances held were ±0.0002 inches, with a positioning pitch between holes of 0.0080 inches.

What’s the biggest hole in the world?
In terms of depth below the surface, the Kola Superdeep Borehole SG-3 retains the world record at 12,262 metres (40,230 ft) reached in 1989, and is still the deepest artificial point on Earth.
What is the smallest hole in the world?
The experts at the University’s Manufacturing Engineering Centre, are drilling holes as small as 22 microns (0.022 mm) in stainless steel and other materials.
What is a micro drill bit used for?
These very hard, solid tungsten carbide, micro twist drill bits are excellent for producing smooth, precision holes and drilling through all hard metals. Ensure a steady hand when using these drills, ideally used at high speed in a pillar drill.

In which process drilling small diameter holes of 0.025 mm is possible?
One of the major advantages of laser drilling over conventional drilling is that there is no contact between the tool and the workpiece, eliminating delamination caused by the thrust force and vibration of the drill bit. Drilling small diameter holes is possible, down to 0.025 mm.
Can wire EDM make holes?
With more than 30 years’ experience in the industry, American Wire EDM is a trusted resource for EDM hole popping. We utilize state-of-the-art, CNC-operated EDM machinery to drill blind- or through-holes as small as 0.010” in diameter in materials as thick as 11.61”.

What is the smallest size hole you can drill?
We have some of the most advanced hole drilling capabilities and are continually developing new processes to drill holes as small as 1 micron.
But read more… Engineers and scientists at Cardiff University are appearing in this year’s edition of the Guinness World Records book for the smallest hole ever drilled — at least with human-made tools. By using a process named ‘electro-discharge machining’ (EDM), they’ve drilled holes just 22 microns wide.
What is the minimum size a drilled hole can be through PCB?
Technical limitations in the manufacturing process, including plating and available drill bits, limit the minimum size a drilled hole can be through a PCB. At Bittele Electronics, our minimum drill hole diameter is 0.15mm for standard holes and 0.1mm for laser drilled holes.
How small can microdrilling holes be made?
They demonstrate the very small holes that the shop is capable of producing by the EDM microdrilling process. The apertures range in size from 10 micrometers (0.0004-inch) diameter for the smallest to 1,000 micrometer (0.040-inch) diameter for the largest.
