Drill chuck

Abstract

The drilling clamp comprises a body with a threaded hole (3.1, 3.2, 3.3) with a screwed-in drilling sleeve (2.1, 2.2) having a thread for temporarily securing the sleeve to the element subjected to drilling operations, wherein the drilling sleeve (2.1, 2.2) is terminated with a knob with a knurled surface or a surface intended for a wrench, used to press the sleeve (2.1, 2.2) to the surface being drilled, countersunk or reamed, and combinations of drilling clamps connected by connectors through threaded holes (3.2) can be created, which can co-create complex drilling devices.
