Только через пару заточек и угол гайки източится

Заточить грани под угол 120 градусов между собой это только пол дела. Нужно еще чтоб сами грани имели угол к оси вращения. Иначе сверло будет только елозить по поверхности. Собственно по этому в ролике и не показывается как сверлят сверла после такой "заточки". Поэтому ценность видоса около нулевая. Да и вообще заводская заточка под 120 градусов как по мне не сильно хороша, да сверло долго живет но сверлит при этом далеко не айс, предпочитаю сразу перетачивать на более острый угол.

реально только для сверл большого диаметра. И крепить сверло нужно ухитриться правильно, иначе выйдет херня.

А затылочные кромки под 90 затачивать не обязательно что ли?

треугольники должны быть выбраны разной высоты, после заточки одной плоскости сверло в приспособе поворачивается на 180 градусов. Этим достигается угол к оси.

Это бред. Оно будет сверлить только потому,что оно металлическое,и только что-то мягкое.)))))
