Product Introduction

This 22/25 hex drill rod is integrally forged from premium alloy steel and processed by multi-stage quenching and tempering heat treatment. It boasts great toughness, outstanding impact and bending resistance, and is not easy to bend or break in underground rock drilling work. The hexagonal rod ensures stable clamping and efficient torque transmission. Both-end threads are precisely CNC machined with standard tooth form for tight connection with bits and couplings, enabling fast assembly and replacement. The smooth central water passage delivers steady flushing flow to remove rock dust and cool the bit, preventing sticking. It is compatible with pneumatic rock drills, widely used for mine tunneling, bolt support and quarrying. As an original manufacturer, we carry out strict flaw detection. Various lengths and custom specifications are available, packed in wooden cases, ready for delivery with formal invoices.
