KGR Industries produces DTH Hammers and Bits for down-the-hole drilling applications in mining, water well drilling, quarrying, civil engineering and other rock drilling operations. The range includes a variety of DTH hammer designs and button bits, designed with drilling requirements such as hole diameter, shank arrangement, equipment compatibility and operating conditions in mind.
KGR manufactures DTH hammers in valve and valveless designs and offers KGR DIAMOND DTH Button Bits in hole diameters from 3 inches to 24 inches. Button bits are available for major DTH hammer brands, providing options for various drilling equipment configurations.
DTH HAMMER AND BUTTON BIT RANGE
DTH Hammer Series
KGR Industries offers DTH hammers in BR, RK, Cheetha, DHD, Digger and SD Series. The range comprises KGR BR 2, KGR RK3, KGR CHEETHA, KGR DHD35, KGR DHD 360, KGR D40, KGR D45, KGR D65, KGR D85, KGR SD6, KGR SD8 and KGR SD10.
The hammer series and models of KGR’s DTH hammers for various drilling equipment configurations are as follows. The hammer configuration is to be chosen depending on the drilling machine, the required hole diameter, the shank configuration, the air supply and the operating conditions.
KGR’s valve and valve-less hammer designs are designed to reduce energy consumption and maintenance requirements and to allow for easy disassembly and reassembly.
DTH Button Bits
KGR DIAMOND DTH Button Bits are available for all major DTH hammer brands and sizes from 3” to 24” hole diameter. The range comprises configurations of Cheetha, Panther, DHD-340, Mission-4, SD-4, QL-40, DHD-360, QL-60, Mission Mega, SD-6, COP-64, SD-8, DHD-380 and SD-10.
The button bit should be designed in accordance with the hammer, hole diameter required, formation being drilled and the operating conditions. The matching of these factors assists in determining a proper drilling combination.DTH HAMMER AND BIT SPECIFICATIONS
DTH drilling components operate as part of a complete drilling assembly. Selecting a suitable combination therefore involves more than the required hole diameter. Hammer type, shank compatibility, bit size, operating pressure, air consumption, drilling formation, and equipment configuration should be considered together.
| Specification | What to Check |
|---|---|
| Hole Diameter | Required borehole diameter and corresponding bit size |
| Hammer Model | Suitable hammer series and model for the drilling setup |
| Shank Type | Compatibility between the hammer, bit, and drilling equipment |
| Operating Pressure | Pressure required by the selected hammer |
| Air Consumption | Compressor capacity available for the hammer |
| Rock Formation | Hardness, abrasiveness, fractured or variable strata |
| Connection | Thread and connection requirements of the drilling assembly |
KGR supplies technical specifications for every model. The technical sheet of the KGR DIAMOND 40 mentions the K40100 hammer with the same shank types SD-4, QL-40, DHD-340 and COP 42. It also features a 38 kg hammer weight, a 98 mm outside diameter, an operating pressure range of 150 to 350 PSI, and an air consumption of 190 to 480 CFM. These specifications are for the KGR DIAMOND 40 and should not be used for other hammer series without verification.
Matching the Hammer and Bit
Choose a DTH hammer and button bit as compatible components of the drilling system. The required hole diameter is the basic bit requirement, while the hammer and shank configuration must be compatible with the drilling machine and the existing drill-string arrangement.
Information such as the current hammer or bit model, shank type, hole diameter, drilling formation, compressor capacity and operating pressure can help determine the right configuration for what to replace with.
APPLICATIONS AND SELECTION OF DTH DRILLING PRODUCTS
DTH drilling is used for applications where impact energy must be delivered directly at the bottom of the borehole. KGR discusses DTH products for mining, water well drilling and civil engineering applications. The company’s drilling range also includes quarrying and other rock drilling needs.
KGR’s DTH products are used in applications such as:
- Mineral exploration and mining
- Well drilling for water
- Drilling and mining of rock
- Construction projects of civil engineering
- Drilling for construction
- Drilling operations on DTH
Selection of products is an important factor of drilling formation. Hard and abrasive rock, fractured strata, changing ground conditions and required hole diameter and depth of drilling can all impact the hammer and bit configuration needed for a project.
Factors to Check Before Ordering
Buyers should establish the following before choosing a DTH hammer or button bit:
- Hole diameter required
- Current drill and hammer setup
- Type of shank
- Rock formation or properties
- Depth of drilling to be done
- Capacity of the compressor
- Operating pressure available
- Current drill pipe connection
- Necessary quantity
This enables the possibility of evaluating the product configuration in terms of the actual drilling system instead of choosing components on the basis of size alone.
Drill-string compatibility is also important because KGR makes friction-welded Drill Pipes for drilling applications in a range of sizes and configurations.
MANUFACTURING, QUALITY AND CUSTOM DTH SOLUTIONS
KGR Industries manufacture DTH hammers, button bits and drill pipes under the brand name KGR. The company's published information includes details of its manufacturing capabilities including friction welding and induction hardening. KGR also states that its products are tested rigorously by technically qualified engineers and technicians.
KGR states that DTH hammers are made of high-quality alloy steel and are subject to radiographic and ultrasonic testing. Its technical documentation also says that different types of DTH hammer and button bits can be produced according to customer specifications.
Quality-Focused production
DTH hammers and button bits operate under the effects of repeated impact, rotation, air pressure and abrasive drilling conditions. So, when choosing drilling components, factors such as material quality, machining accuracy, compatibility and product testing are important things to consider.
KGR’s product information lists alloy-steel construction and radiographic and ultrasonic testing for its hammer products. The technical data sheets also provide model specific specifications that allow the customer to assess each configuration against the requirements of their drilling application.
Choosing the Right DTH Combination
In choosing DTH Hammers and Bits, the hammer, button bit, drilling equipment, air supply and ground conditions must be taken as a whole.
KGR’s range offers several hammer series and button-bit combinations for various drilling needs. The customer can initially set the required hole diameter and equipment configuration, then match the hammer and bit according to the applicable technical specifications.
KGR’s DTH Hammer Drill Guide describes the working process, main components, impact mechanism, rotation, feed force and flushing for customers who want to understand the working principle more clearly before choosing the components.
KGR’s technical documentation also mentions that DTH hammers and button bits can be made according to the specifications of the customer.
