Taper drill rod is used for rock drilling, blasting holes and other drilling works in quarries, coal mines, traffic, and other constructions. It works with taper drill bits and is available in different lengths for various applications. Our taper drill rods come in a variety of taper angles. Generally, light-duty rock drills usually use a 7° taper or smaller, while heavy-duty rock drills mainly use 11° or 12° taper angles. The basic requirement is that taper drill rods and taper drill bits must share the same tapered degree. We provide tapered rods in a full range of shank configurations and steel hex diameters for hand-held pneumatic drilling needs.

Frequently Asked Questions
Q: What are the primary applications of tapered drill rods?
A: They are widely used for rock drilling, blasting holes, and other excavation tasks in quarries, coal mines, and infrastructure construction projects.
Q: Which taper angles should I choose for my drilling equipment?
A: Generally, 7° or smaller angles are used for light-duty rock drills, while 11° and 12° angles are designed for heavy-duty drilling machines.
Q: What materials are your tapered rods made from?
A: Our rods are manufactured using high-quality carbon steel and alloy grades such as 95CrMo, 55SiMnMo, and 23CrNi3Mo for maximum durability.
Q: Do the rod and bit need to have the same taper degree?
A: Yes, it is a technical requirement that the tapered drill rod and the drill bit must have the exact same taper angle to ensure a secure fit and efficient power transfer.
Q: What is the standard packaging for international shipping?
A: We typically package the rods in reinforced wooden cases or in secure bundles to prevent damage during transit.
Q: What shank sizes are available for hand-held drilling?
A: We offer a full range of hex diameters, most commonly Hex 22mm and Hex 25mm, with various shank lengths to meet pneumatic drilling needs.
