Carbon Steel Integral Drill Rod for Rock Drilling
Integral drill rod?is a drilling tool for small-diameter shallow-hole rock drilling, which usually made of 19 mm, 22 mm, and 25 mm hexagonal hollow steel. It usually has fixed length and has a forged collar with a shank at one end and a cutting structure at the other. And it has a wide application like quarrying, construction, tunneling, underground mining, road construction, trenching, etc.

Precautions for use
1. Before use, check whether the rod is bent. For bent integral rod, straighten the rod before use (do not use hammering or heating to straighten). Do not remove the plastic cover before using the product to prevent the water hole from being blocked.
?
2. For hard rock with strong corrosion and rock with multiple cracks, it’s better to use a cross-shaped integral rod.
3. When the width of the cutting edge of the integral drill head is worn to more than 3mm, please grind in time. When?alloy is severely worn, please stop?grinding. When the head has an inverted cone, stop grinding?to eliminate the inverted cone.?Otherwise, the alloy will be severely worn and even the drill will be stuck;
4. Adjust the working air pressure according to the rock conditions. The standards are normal rotation, fast penetration, no bending of the drill rod and normal powder discharge;
5. When the drilling depth is ≥2000mm, use a set of drill rod. And short rod to open the hole, and long rod to continue drilling, so as to increase the service life of the whole rod.
The integral drill?rod?has the characteristics of less impact energy loss, high rock drilling efficiency, fast drilling speed. And there no need to load and unload the drill bit. It can also work?in various mining projects when combined with low-power gasoline rock drill, pneumatic and hydraulic rock drills.
