Model: Integral Drill Rod

Length: 1000mm-6000mm

>> 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: 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 Rods

Diameter:25-87 mm

Length:600-6095 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.
