Frequently Asked Questions (FAQ)
⬥ What sizes of tapered drill rods are available?
We offer tapered drill rods in lengths ranging from 400mm to 8000mm, with taper angles of 4, 6, 7, 11, and 12 degrees. Shank sizes include Hex 22mm*108mm, Hex 25mm*159mm, and Hex 19mm*108mm.
⬥ What materials are used to construct these drill rods?
The drill rods are manufactured using high-quality carbide and high-quality alloy steel to ensure maximum durability, wear resistance, and high performance in hard rock drilling environments.
⬥ Can you produce customized lengths and carbide sizes?
Yes, we can custom manufacture drill rods with specific lengths, carbide sizes, and designs to match your specific machinery and rock drilling requirements.
⬥ What are the primary applications for tapered drill rods?
Tapered drill rods are primarily utilized in granite and marble quarrying, gold mines, railways, tunnel excavations, and other hard rock drilling construction projects.
⬥ Do you require a Minimum Order Quantity (MOQ)?
We have no MOQ requirement for testing and trial orders, allowing you to evaluate our product quality before making bulk purchases.
⬥ What is the difference between tapered drill rods and integral drill steel?
Tapered drill rods connect to a detachable taper bit and are highly versatile. Integral drill steel rods have a fixed carbide bit directly integrated onto the rod end, which is suitable for smaller, standard hole drilling.
