QL50 DTH Hammer

 

The QL50 DTH Hammer is mostly determined by the size of the hole and the kind of rock formation. The appropriate hammer position should provide just enough space for cuts to depart the hole while yet being as near to the target hole diameter as is practicable.

 

A fantastic option for rock drilling equipment. We can increase your profits. We can accommodate your drilling requirements for a range of uses, including mining, quarrying, geothermal energy, water well drilling, and anchoring.

 

The LEANOMS Group, based in Xiamen, China, is the premier worldwide productivity partner with an integrated professional R&D, production, market, and service system. We have skillfully supplied Rock Drilling Tools in a range of applications for more than 20 years as the top manufacturer and service supplier. We are drill experts! We also understand your industry!

 

QL50 DTH Hammer is used to drill holes through several varieties of rocks. To spin the bit in the ground in combination with DTH hammers, drill hammer bits are constructed with a spline drive. Drill bits can drill a range of hole diameters since they are available in a number of sizes and designs. Our range of QL50 DTH Hammer is constructed with high-quality components to provide you with the ideal mix of penetrating power and bit durability. We provide a large selection of standard and bespoke drill bits on a variety of shanks with different head shapes for any purpose.

When it comes to drill bits equipped with a Down-the-Hole (DTH) Hammer, there are two main variations: those with a foot valve and those without a foot valve. Each configuration offers distinct characteristics and advantages.

 

QL50 DTH Hammer Drill Bits with Foot Valve:
Drill bits equipped with a foot valve have an additional component incorporated into their design. The foot valve is typically located at the bottom of the hammer assembly, just above the drill bit. Here are the key characteristics of drill bits with a foot valve:

 

Retention of Air Pressure: The foot valve helps to maintain air pressure within the hammer assembly during the drilling process. This ensures a continuous supply of compressed air, which is crucial for efficient drilling performance.

 

Reduced Air Consumption: By retaining air pressure within the hammer assembly, drill bits with a foot valve can help reduce air consumption during drilling operations. This can lead to cost savings and increased efficiency, particularly in projects with limited air supply.

 

Improved Hole Cleaning: The foot valve aids in the effective flushing and removal of drilling cuttings from the borehole. It helps prevent the cuttings from clogging the drill bit and obstructing the drilling process, resulting in improved hole cleaning and better drilling performance.

 

Enhanced Penetration Rate: The retention of air pressure by the foot valve can contribute to increased penetration rates. This is because a continuous and consistent supply of compressed air helps deliver maximum impact energy to the drill bit, facilitating faster drilling progress.

 

QL50 DTH Hammer Drill Bits without Foot Valve:
Drill bits without a foot valve follow a more traditional design, where there is no specific mechanism to retain air pressure within the hammer assembly. Here are the key characteristics of drill bits without a foot valve:

 

Simplified Design: The absence of a foot valve simplifies the design of the drill bit and hammer assembly, making it more straightforward and easier to maintain.

 

Potential for Higher Air Flow: Drill bits without a foot valve may allow for higher air flow rates, which can be advantageous in certain drilling scenarios where increased air velocity is required to clear drilling cuttings or when working with harder rock formations.

 

Cost Efficiency: Drill bits without a foot valve are often more cost-effective compared to their counterparts with a foot valve. This can be advantageous in projects with budget constraints or when specific drilling conditions do not necessitate the use of a foot valve.

 

 

Wooden Crates and Pallets: Our packaging solutions are designed with durability in mind. We utilize sturdy wooden crates and pallets to safeguard your valuable drilling tools during transit, minimizing the risk of damage.
