What an LD 4 drilling rod does in quarry drilling
The role of the drill rod in the drilling string
A drill rod connects the drilling machine to the tool working at the bottom of the hole. In our product description, drill rods are built for reliable transfer of drilling energy in quarry and mining applications. On an LD-4, that energy has to reach the bottom of every hole, from shallow line-drilling holes to deep blast holes.
Why rod choice matters on an LD-4 machine
Drill rods are working parts, and they sit between a well-built machine and the rock. A rod that does not suit the machine or the job costs drilling time. That is why quarry owners look for an LD 4 drilling rod manufacturer that knows the machine the rods will run on.
What buyers of LD-4 drill rods usually need
Quarry owners and contractors who search for an LD 4 drilling rod manufacturer in India usually want three things: the right rod length for the machine, confirmation that the rods suit their tooling, and a supplier who will still be there when they need the next batch. This page explains how we handle each of those points.
What to check in an LD 4 drilling rod manufacturer in India
Rod length
The LD-4 is listed with a drill rod length of 1.5 meters (4 feet). Confirm the length with any LD 4 drilling rod manufacturer before you order, because a mismatch can stop a machine.
Hole diameter and tooling
The LD-4 drills holes of 3 to 7 inches. Rods work together with the hammer or bit at the end of the string, so ask the supplier to confirm that the whole set is compatible. We publish no rod sizes or thread details on the website, so our team confirms these with you directly.
Machine knowledge and supply
A manufacturer that builds the LD-4 itself understands how the rods are used in practice. Leelanjali Rock Drill makes the LD-4 Slim Drill Machine and lists drill rods alongside it.
Quotes and enquiries
Prices depend on the rod and the quantity, so we give quotes rather than a fixed list price. Send your machine model, rod length and quantity through the contact page and the team will reply with the details.
