Description

Integral Drill pipes usually have forged collar, and are fixed length with a shank at one end and
a bit at the other. This provides a hexagonal chuck section to provide leverage for the rotation
chuck bushing. They are able to drill to a depth equivalent to their effective length. The bit usually may
consist of a single chisel shaped tungsten carbide insert. Holes are typically drilled in 0.4m increments to accommodate the air-leg feed length. To drill deep holes (up to 2.0m), the rods are designed to be used in a series where the length of any rod used is longer and the head size is slightly smaller than the one used just before it in the sequence. To do this, a series of rods must be produced so that the bit diameter is reduced for each increase in length of rod to prevent jamming of the bit in the hole.
HENGLONG Integral Drill pipes 's raw material is Z708(40SiMnCrNiMo)/55SiMnMo.
HENGLONG provides a variety of integral drill pipes and plug hole rods in a full range of lengths and steel hex diameters for all of your hand-held pneumatic drilling needs.
Integral drill pipe's shank sizes 82.5 mm*22mm(3 1/4”*7/8”), 108mm*22mm(4 1/4”*7/8”), 108mm*25mm(4 1/4”*1”), 159,*25mm(6 1/4”*1). Lengths: 400mm to 6400mm(1’4”-21’). Head diameters: 27mm to 40mm.

Performance

High spindle speed, with the utilization rate of the percussive force 18% to 25% higher than using separate drill bits;
Easy to remove the integral drill rod instead of removing the drill bit, which avoids breakage, cracking of drill bit and breakage of the conical end of drill rod;

Application

Integral Drill Pipe is mainly used in small-hole drilling, such as stone quarrying,foundation drilling, tunneling, underground mining,road cutting, and trenching and so on, and equipped with small power rock drills, like air leg rock drills, hand held rock drills, etc. It can reduces the expense of impact energy, improves the drilling speed and efficiency, which can be used for drilling bore hole diameter from 23mm to 45mm usually.
