AW BW NW HW Φ73 Φ89 Water Hardening Drill Rod
Water Hardening Drill Rod Description
Drill Rod using thread system. Drilling precision can be further improved by using this as the first rod in a normal drill string. Furthermore, since this is a speed rod design it will produce straighter holes and at least 10% higher penetration rate in good rock conditions compared to rod and coupling sleeve combination system.
Overall capacity:
1. A variety of hot-rolled seamless pipes of large diameter and small-diameter pipes complete range of sizes, from the outside diameter of 21.3mm to 1500mm, wall thickness from the 2mm to 250mm.
2. A comprehensive selection of materials available in carbon steel, alloy steel and other special materials in accordance with customer requirements.
3. Strong R & D base Top scientists and experts in research centers owned by the Group to develop for the future.
Water Hardening Drill Rod Specifications:
1. High Penetration Rate
2. Longer lifetime
3. Lower Using Cost
4. Excellent cemented carbide
5. AW, BW, NW, HW, PW, BWL, HWL, NWL, PWL
