API Standard Spiral Blade Water Well Drilling Tools for 152 - 711 mm Dia Hole Range

Api 7-1 standard integral spiral blade stabilizer for big hole water well drilling

Introduction

Integral Spiral Blade Stabilizer is made from AISI 4145H modified alloy steel, and completely meets the requirement of API Spec 7-1 standard. It is mainly used to stabilize the drilling tools in the process of drilling hole. It also can be separated into Drill String and Near-bit types. During the production process of Drilling tool stabilizer, traceability is maintained from the receipt of raw material to completion of final products, and serial numbers are die-stamped on each work piece body. During each manufacturing process, inspection and test are performed to make sure that every piece is quality.

Optional Stabilizers:
We offers several options for IBS, in both alloy steel and non-magnet materials:
Spiral Integral Blade Stabilizer;
Straight Integral Blade Stabilizer;
Non-Magnet Integral Blade Stabilizer;
