Manufacturing & Production
Frequently Asked Questions
What is a Taper Rod Integral Drill Steel?
Integral drill steel (also known as integral drill rods) is a rock drilling tool that combines the steel rod and the carbide bit into a single unit. It is widely used in hand-held rock drilling, underground mining, and small hole blasting.
Which taper angles are available for your drill rods?
We supply drill rods with multiple taper angles to meet different drilling requirements, including 4°46", 6°, 7°, 11°, and 12°. Taper 7° and 11° are the most commonly used angles for medium to hard rock formations.
What premium material is used in manufacturing?
Our taper drill steels are manufactured using high-quality 55SiMnMo alloy steel. This provides exceptional strength, high wear resistance, and long-lasting fatigue life in tough drilling conditions.
What is the difference between Chisel and Cross bits?
Chisel bits are generally used for soft to medium-hard rock structures and offer fast drilling speed. Cross bits are ideal for hard, fractured, or abrasive rock types as they provide better stability and drill straighter holes.
What shank sizes and lengths do you offer?
Standard shank dimensions include Hex19mm, Hex22mm, and Hex25mm. We provide a wide range of lengths starting from 400mm up to 6400mm to accommodate various mining and quarrying applications.
