Bladed spiral stabilizers KS
Bladed spiral stabilizers KS

Vane spiral calibrators (version: sleeve-nipple) of the KS type – are designed to calibrate the borehole walls to the nominal diameter with wear of the rock cutting tool, as well as centering and improving the operating conditions of the rock cutting tool while drilling in soft (M), medium (C), hard (T) and hard (K) low-abrasive and abrasive rocks.

The calibrators are solid-milled (the body of which together with the blades is one whole) and welded (where the blades are welded).
