The drill rods and casing provided by Dalemei ensure the steel grade and mechanical performance. The pipes are subjected to non-destructive testing using eddy current and ultrasonic testing to ensure that there is no damage inside the pipes and the quality is good.
Impregnated Diamond core bits Description: The impregnated diamond drill bits are the most commonly useful bits in the mineral exploration industry, as they have the widest range of application. The high grades of synthetic diamond are distributed in the bit's matrix. Casing Shoe: The casing shoe bit is mainly used in handling casing tube in the shallow earth surfaces, and we have casing shoes bit in different hardness to better fit various casing tube bits. The casing shoe diamond bit is mainly made up of diamond single crystal steel body, tungsten carbide and polycrystalline diamond. Main functions of casing shoe: 1): Protect casing ends from distortion. 2): Help casing pass through stratum to bed rock. 3): Carry mud to earth surface. 4): Help down-pass of casing when drill rod is in hole. size available: Q series(Wireline Series): AQ, BQ, NQ, HQ, PQ, SQ,BQ3, NQ3, HQ3, PQ3 W Series: RW, EW, AW, BW, NW, HW, PW, SW, UW, ZW, HWT, PWT, BWS, NWS Metric Series: 46, 56, 66, 76, 86, 101, 116, 131, 146 X Series: RX, EX, AX, BX, NX, HX, PX, SX, UX, ZX TT series: NQTT, HQTT,PQTT
The pneumatic pick is a tool with compressed air as its power. The compressed air is distributing alternatively through the tube-shaped distributing valve into either end of the cylinder, so that the hammer is reciprocating motion in it, which impacts the tail-end of the pick rod and drives the pick rod into the rock or strata of mine, thus causing them to split into pieces.

DRILL RODS: The tool steel drill rod pieces (O-1, A-2, D-2, H-13, S-7, M-2, and W-1) are usually machined in the annealed state and then heat treated to make hardened, long lasting tools. The Applications Table below shows the classes, steel grades, hardening methods, and typical applications for Drill Rod. To use the table, find the class in the left column. To find out what is drill rod used for, find the steel grade in the table below and read the applications in the right column of the same row. DRILL PIPES: Available Ranges: Sizes : 3",3 ½", 4 ½" & 5 ½" Length : 5', 10', 13', 15', 20' & 30'

The drill rod is the part that links the drill bit and the shank adapter in the rock drill and undertakes the task of transmitting the impact energy to the drill bit, the rotational torque, and the flushing medium. In actual use, the force conditions of the drill rod are harsh, and it is easy to consume a large number of wearing parts. Product Category Drill rods include tapered drill rods and threaded extension rods according to their connection methods. Tapered drill rod: It is suitable for drilling shallow holes, the tail is connected with the rock drill using the shank adapter, and the tapered part of the head is connected with the drill bit. Threaded extension rods: It is more suitable for drilling deep holes. It can use a sleeve with female threads to connect two drill rods with male threads. With the deepening of the hole depth, multiple drill rods can be connected. It is very convenient to remove the rod from the connection after chiseling. Except by connection type, drill rods include light drill rods and heavy drill rods. Light drill rods include tapered drill rods, shank rods, and integral drill rods. Heavy drill rods mainly include drill rods used for drifting and tunneling rigs, benching drilling rigs, and Open-cutting drilling rigs. Length Light drill rods: 300mm-6000mm(without shank, the conventional length of the shank is 108mm). Heavy drill rods: 600mm-2000mm(Drill rods less than five meters are available). 1. We have professional technical, procuring, marketing, order management, and after-sale service teams, which can provide customers with pre-sale technical solution consultation and product selection suggestions, in-sale order management, and after-sale on-site technical guidance and other services. 2.
