Rock Drilling Tools are indispensable for penetrating hard-faced rock formations like granite, facilitating essential operations such as bench drilling, quarry drilling, and creating secondary holes for blasting. In this comprehensive guide, we&#;ll delve into the intricacies of rock drilling tools, from their components to their applications, empowering you with the knowledge to make informed decisions for your drilling projects.
KSQ Technology supply professional and honest service.
It encompasses a variety of equipment designed to withstand the rigors of drilling through tough rock formations. These tools typically consist of drill bits, drill rods, shank adapters, and couplings, each playing a crucial role in the drilling process.
Bench Drilling: Commonly employed in mining and construction projects, bench drilling involves drilling horizontal holes on elevated benches to extract minerals or create access for further excavation.
Quarry Drilling: Quarry drilling is essential for extracting dimensional stone, gravel, or other materials from natural rock formations, requiring precision drilling to maximize yield and minimize waste.
Secondary Holes for Blasting: In blasting operations, secondary holes are drilled to enhance the efficiency and safety of the blasting process, allowing for controlled fragmentation of rock masses.
Selecting the appropriate drilling tools is paramount to the success of any drilling project. Factors such as rock hardness, drilling method, and environmental conditions must be carefully considered to ensure optimal performance and cost-effectiveness.

Model: Integral Drill Rod
Length: mm-mm
>>Application
Integral Drill Steels are a fixed length with a shank at one end and a bit at the other ,and are able to drill to a depth equivalent to their effective length.The bit may consist of single chisel-shaped tungsten carbide insert or three such inserts.To drill deep holes,the rods are designed to be used in a series where the length of any rod used in longer than the one used just before it.
Model: Tapered Drill Rod
Diameter: 19mm - 25mm
Taper Degree&#;4°, 6°, 7°, 11°, 12°
>>Application
Tapered drill rods are used in granite and marble quarry, gold mine, railway, tunnel, etc. for drilling.tapered drill rods have a tough life, transferring the percussion energy from rock drill to drilling bit and then into the rock. They're also subjected to high bending stress, not to mention
Model: Tapered Button Bits
Button size: 32&#;34&#;36&#;38&#;40mm
Taper angle:7 °/11°/12°
>>Application
The Rock Drilling Bits are made from grade hard alloy and special steel, generally matched with the light-duty rock drill, to drill the rock hole within diameter of 50mm. The drill tools are used in metallurgy mine, geological exploration, water conservancy construction, electricity, traffic, tunnel, quarry, national defence stone project etc
Model: Cross Drill Bits
Degree: 4,6,7,11,12
Diameter:22-55mm
>>Application

The cross rock bit can be used under any rock drilling condition, it's hardly impacted by the model of drill rig and the rock performance
Model: Chisel Drill Bit
Degree: 4,6,7,11,12
Diameter:20-40mm
>>Application
Tapered equipment affords drillers the ability to change drilling bits whilst still using the same drilling rod. Drillers choose tapered cross type bits if the goal is to minimize hole deviation in small hole range drilling.
Model: Threaded Drill Bit
Bit Diamond:33 to 152 mm
Button Angle:30°,35°,40°
>>Application
The thread button drill bits are made by high quality alloy steel bar and tungsten carbides. Through heat treatment, our drilling tools are tough enough to meet rock drilling demands and have the least loss of energy while drilling the rocks. Besides, we can design customized thread button drill bits according to different drilling application, and custom drill bits are applicable to drill soft rock, loose-medium rock and hard rock.
Model: Threaded Drill Rods
Diameter:25-87 mm
Length:600- mm
>>Application
Thread drill rod other names extension rod, Extension drill steel, Extension drill rod, and Extension steel, M/F rod ( Speedrod ) , Produce Hexagonal and round cross sections, Hexagon rods are more rigid, heavier and transfer energy more efficiently, while increasing flushing. Round rods are generally lighter than hexagonal rods and are normally used in extension drilling applications. With the longer steel tending to be larger in diameter, conventional extension steel is characterized by a duplicate thread on each end of the steel.
Model: Threaded Cross Bits
Bit Diameter:33-80 mm
>>Application
The cross rock drill bit can be used under any rock drilling condition, it's hardly impacted by the model of drill rig and the rock performance. Generally, chisel bit are mainly used for hard rock, cross bit and button bit are mainly used for fissured rock.
Model: Shank adaptor
Length: 300mm-800mm
Thread:R32,R38,T38,T45,T51
>>Application
Integral Drill Steels are a fixed length with a shank at one end and a bit at the other ,and are able to drill to a depth equivalent to their effective length.The bit may consist of single chisel-shaped tungsten carbide insert or three such inserts.To drill deep holes,the rods are designed to be used in a series where the length of any rod used in longer than the one used just before it.
