Small Hole Drilling Tapered Drill Rods H22

---

Connected at one end to a rock drill and at the other to a taper drill bit, the taper drill rod serves as the conduit for transmitting power, enabling the drill bit to perform its work. An advanced version of integral drill rods, the tapered drill rod typically features a forged collar that ensures the shank maintains the correct striking face position within the rock drill. The effective length of the tapered drill rod, measured from the collar to the bit end, typically ranges from 0.6 meters to 3.6 meters.

Parameters:

• Shank Sizes: Hex.19mm, Hex.22mm, Hex.25mm
• Taper Degrees: 4°46’, 6°, 7°, 11°, 12°
• Length: 400mm to 8000mm

Features:

• The drill rods undergo a carburizing process that enhances their surface hardness, thereby improving wear resistance and extending their lifespan.
• Made from 23CrNi3Mo, a material comparable to Sandvik Sandbar 64, the drill rods offer exceptional performance.
• Combining cost-effectiveness with reliable performance at a reasonable price.
• A comprehensive range of drill rod types tailored for diverse drilling applications.
