Eccentric Casing System Bit Link 3"~10" Hammer ODEX System
Reliable performance Symmetric Casing System With Reamer-IV For Complex formation Drilling Product Description ODEX is an excellent option when unconsolidated formations are too dense or cobbly for Auger Drilling. ODEX is a down-hole air hammer system that is designed to advance casing during drilling. Once a desired depth is reached they eccentric bit can be retrieved leaving the casing in place for sampling or installations. When the bore-hole is complete, the casing is
Symmetric Casing System With Reamer IV For Complex Formation Drilling
Reliable performance Symmetric Casing System With Reamer-IV For Complex formation Drilling Product Description 1.Drilling Straight and fast Theoretically , Concentric drilling makes sure the hole in all formations such as gravel bed , sand bed and pebble bed etc is considerably straight , the drilling speed fast and the drilling torque relatively small . 2.The torque for Concentric drilling is much less than for eccentric drilling. A smooth and steady drilling may be achieved
QL50 152mm DTH Button Bits 5 Inch Bits For Concrete Drilling And Blasting
QL50 152mm DTH Button Bits 5 Inch Bits For Concrete Drilling And Blasting In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.

12 Inches Dth Drill Bits Hammers High Pressure Drill Deep Hole Length
In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length. DTH bits are paired with their corresponding hammers (by drilling hole diameter and spline configuration). Customers can customize their DTH bits in various ways, such as changing the tungsten

Carbon Steel Dth Hammer Button Bits Water Well Drilling Cir90 90mm Low Air Pressure
Descriptions: DTH bit is for rocks cutting , and subject to severe stress from the striking piston as well as from the abrasive cuttings passing the bit at high velocity. When selecting the right bit for optimum performance you have to balance penetration against bit life. On occasion you can successfully sacrifice bit life for penetration, remember the rule of thumb that states that a 10% increase in penetration covers at least a 20% loss in bit life. Our products are
