Micro Hole Drilling Solutions for Precision Manufacturing Excellence
In the age of advanced manufacturing, micro hole drilling has become a cornerstone of precision engineering. From aerospace to medical, electronics to automotive, the demand for ultra-small, high-accuracy holes continues to grow—pushing manufacturers to adopt smarter, faster, and more reliable drilling technologies.

What is Micro Hole Drilling?
Micro hole drilling refers to the process of creating holes typically smaller than 1mm in diameter, often ranging from 0.05mm to 0.5mm. Unlike conventional drilling, this process requires specialized high-speed machinery, superior tool control, and advanced cooling systems to prevent deformation, tool wear, and inaccuracies.
These micro holes are used in:
Medical implants and surgical devices
Printed circuit boards (PCBs)
Fuel injection systems
Aerospace turbine blades
Filtration and fluid control components
Why Micro Hole Drilling Matters
Micro holes are often mission-critical. A slight deviation in size, roundness, or depth can impact product functionality or safety. That's why manufacturers are turning to CNC micro hole drilling machines designed specifically for high-speed, high-accuracy small diameter drilling.
