Drillen

Drillen is a Dutch verb that encompasses several related activities tied to making holes or to practicing through repetition. The meaning depends on context and sector, with common uses in mechanical work, training, and the energy industry.

Mechanical drilling refers to using a drill to bore holes in materials such as wood, metal, or plastic. Tools range from handheld cordless or corded drills to drill presses and hammer drills. The process usually involves securing the workpiece, selecting a suitable drill bit, and applying controlled torque and penetration depth. Proper technique and safety measures, including eye protection and clamping, are essential to avoid injuries or damage.

Training drills refer to repeated practice designed to improve skill, speed, or coordination. In military, sports, music, or education, drills establish routines, timing, and precision. A drill can involve a sequence of predefined steps, commands, or patterns intended to build automatic performance.

In the energy industry, drilling denotes the creation of boreholes to access subsurface resources, most notably oil and gas. A drilling rig supports the drill string, casings are installed to stabilize the hole, and drilling mud helps manage pressure and remove cuttings. The operation proceeds from site preparation to drilling, casing, cementing, and completion, under strict safety and environmental regulations.
