RC Drilling String Hammers for Drilling Sampling are specialized pneumatic tools designed specifically for reverse circulation (RC) drilling, a technique widely used in mineral exploration and geological sampling. These hammers drive the drill bit into the ground and use air pressure to lift cuttings from the drilling hole to the surface, ensuring clean and uncontaminated samples are collected efficiently.

Length:1500-6000 mm

Depth: 300-5000 m

>> Application

This series reverse circulation pipes can increase penetration in lost-circulation formation, reduce driling fluid consumption, protect reservoir stratum and save the cost of other consumption tools. ln additional, the pipes can be worked in two direction circulation drling ways to control the well driling. By reverse circulation method to ki the we the heawy mud can be transferred directly to the bottom of well, no periodic circulaton and save time.

Length:70-235 mm

Diameter: 59-146 mm

>> Application

Jcdrill supplies various types of adaptor subs and couplings to enable connection of rods to different rods, core barrels, casings tube cutters, and water swivels.Adaptor subs and coupling can be customized

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: 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.
