Product Description:

Different rock formations and rock drills require different taper angles. When drilling with high impact hydraulic rock drills in medium-hard to hard and abrasive rock formations, a wide taper angle is normally used. Taper angles of 11 and 12-degrees are normally used on modern drill rigs. For low impact rock drills and softer rock formations, a narrow taper angle of seven degrees is used. A 7-degree angle can also be used if bit spinning is a problem when using 11 and 12-degree equipment. In addition, a 4, 46 degree angle is ideal for soft rock when you're using pneumatic or hydraulic drill rigs - to prevent bits from spinning or becoming detached.

Features:

• Carburizing process is applied to promote surface hardness, thus grant better wearing quality and lifespan for the drill rods;

• 23CrNi3Mo, which is in same league as Sandbar 64, is applied as drill rod material.

• Cost-effective, good performance with reasonable price.

• Complete types of drill rod for various drilling scenarios.

Technical Parameters:

Applications:

The H25 Hexagonal Drill Rod is particularly well-suited for use in deep drilling applications. Its unique hexagonal shape provides increased stability and durability, making it an ideal choice for drilling in tough environments. The H25 Hexagonal Drill Rod is also an excellent choice for use in geothermal drilling and environmental drilling applications.

Main Drilling duties in tunneling, construction, mining, quarrying, etc.
