Description

( 54) КОМБИНИРОВАННОЕ СВЕР/Ю(54) COMBINED SVER / U

Применение стального корпуса уменьшает хрупкость сверла, позвол   ему надежно работать на изгиб и скручивание.The use of a steel body reduces the brittleness of the drill, allowing it to work reliably in bending and twisting.

Отсутствие ка){авок, наличие продольного среза и пр мой режущей кромки на сверле дает возможность беспреп тственно удал ть стружку из зоны обработки материала.The lack of ka {{avok}, the presence of a longitudinal section and a straight cutting edge on the drill allows unrestricted removal of chips from the material processing zone.
