Products Description LEANOMS
All Leanoms DTH Hammer Numa are constructed internally at our cutting-edge factories. To ensure longevity and quality, all components are precisely made utilizing premium raw materials and put through specialized heat-treatment procedures at our facilities. API Reg pin connectors are standard, which are available with all common backhead connections. Get in touch today for help choosing the right hammer for your drill project and you will get a quotation for reference.
In addition, it offers the following benefits:
1. Due to the unique inner structure of the DTH Hammer Numa, which was created in accordance with the most recent rock drilling theory, deliver maximum energy to the drilling bit, fast drilling speed, and low air consumption.
2. Long life span: the wear-resist of tungsten carbides is 10-20 times higher compared with other similar materials, which greatly extends the life of the carbide DTH button bits.
3. Fewer intemal parts,simple structure,long life span,less failure and easier to maintain because all the parts are heat trated.
4. The multi-head thread connecting the chuck and the hammer's cylinder makes it simple to remove the bit from the DTH Hammer Numa.
5. Tailored product offering covers all your applications and conditions

Products Design Concept LEANOMS
Efficient Energy Transfer:
Numa focuses on maximizing the efficiency of energy transfer from the hammer to the drill bit. The design ensures that the energy generated by the piston is effectively transmitted to the bit, enhancing penetration rates and overall drilling performance.
Valveless Design:
Many Numa DTH Hammers feature a valveless design, eliminating the need for a foot valve. This simplifies the internal structure, reducing maintenance requirements and potential points of failure. The absence of a foot valve enhances the reliability of the hammer during drilling operations.
High-Quality Materials:
The use of high-quality materials, often precision-machined alloy steel, is a cornerstone of Numa's design philosophy. These materials are selected for their durability, wear resistance, and ability to withstand abrasive conditions encountered during rock drilling, ensuring a long service life for the hammer.
Precision Machining:
Internal components undergo precision machining to maintain tight tolerances and ensure optimal performance. Precision machining is a critical aspect of Numa's design to provide consistent drilling results and reliability.
Compatibility with Various Bit Shank Configurations:
Numa DTH Hammers are designed to be compatible with various bit shank configurations. This versatility allows users to choose the appropriate drill bit for specific applications and geological conditions, providing flexibility in drilling operations.
Streamlined Flow Paths:
Internal flow paths are designed to optimize air or drilling fluid flow, facilitating efficient flushing of cuttings from the borehole. This streamlined flow contributes to improved drilling efficiency and helps prevent blockages.
