Drill stands for timber construction, where a hole through a beam has to come out where the drawing says. The fixed stand drills square to around 240 mm depth, taking bits to 320 mm and diameters from 8 to 26 mm. The tiltable version swivels to 45° for angled holes and reaches around 310 mm with bits to 460 mm. Both accept drills with 43 or 57 mm collars, so they fit machines you already own.
