what is QL in drilling?
In drilling, “QL” typically refers to a specific series or design of Down-The-Hole (DTH) hammers and their corresponding drill bits.
“QL” often stands for “Quantum Leap,” a brand name used by manufacturers for their DTH hammer range. These QL hammers are designed for high-performance drilling in various rock formations, particularly in applications such as mining, quarrying, water well drilling, and construction.
The QL series is known for its robust construction, efficient energy transfer from compressed air to the drill bit, and versatility in different drilling conditions, aiming to provide increased productivity and reduced operating costs.
QL 60 hammer specifications
The QL 60 hammer is a widely recognized DTH (Down-The-Hole) hammer designed for various demanding drilling applications.
While specific specifications can vary slightly between manufacturers, here are the common specifications and characteristics you’ll find for QL 60 hammers:
General Specifications:
Shank Type: QL60 (This refers to the standardized connection interface between the hammer and the drill bit, ensuring compatibility). It can also be compatible with COP64GOLD.
Drill Bit Range: Typically suitable for hole sizes ranging from approximately 152 mm (6 inches) to 203 mm (8 inches), though some sources indicate up to 216 mm (8.5 inches) or more.
Backhead Thread (Pin): Commonly 3 1/2″ API Regular.
Hammer Outside Diameter: Around 140 mm to 145 mm (approximately 5.5 to 5.7 inches).
Hammer Length (without bit): Varies but is generally around 1000 mm to 1200 mm (approximately 39 to 47 inches).
Hammer Weight (without bit): Typically in the range of 90 kg to 105 kg (approximately 198 lbs to 230 lbs).
Working Pressure Range: Generally designed to operate efficiently between 10 to 24 Bar (150 to 350 PSI), with some models capable of up to 34 Bar (500 PSI) or more.
Air Consumption: This is highly dependent on operating pressure and can range significantly. For example, at 10.3 Bar (150 PSI), it might consume around 8-9 m³/min (280-320 CFM), while at 24 Bar (350 PSI), it could be upwards of 30-40 m³/min (1000-1400 CFM).
Piston Weight and Stroke: These internal specifications contribute to the hammer’s impact energy and frequency. For instance, piston weight might be around 20-22 kg (44-48 lbs) with a stroke of 95-108 mm (3.75-4.25 inches).
Make-up Torque: The recommended torque for assembling the hammer components, often in the range of 6000-8000 Nm (4500-6000 ft-lb).
Recommended Rotation Speed: Typically between 30-60 RPM.
Recommended Feed Force (Pull Down): Varies with pressure, often starting around 670 kg (1500 lbs) at lower pressures and increasing to over 1800 kg (4000 lbs) at higher pressures.
Key Design Features (often highlighted by manufacturers):
Valved or Valveless Air Distribution: Some QL60 hammers use a traditional foot valve on the bit, while newer designs might feature valveless systems for improved reliability and performance, especially in deep holes.
Robust Construction: Designed with heavy-duty components and hardened materials (e.g., alloy steel for pistons and cylinders) to withstand abrasive conditions and extend service life.
Efficient Energy Transfer: Optimized internal design to convert compressed air into powerful impacts on the drill bit, leading to high penetration rates.
Adjustable Air Flow (Choke System): Some hammers include a choke system to adjust air volume for optimal cutting evacuation, even when drilling under water.
Simplified Design: Often engineered with fewer internal parts to facilitate easier maintenance and reduce potential points of failure.
When choosing a QL 60 hammer, it’s crucial to consult the specific manufacturer’s technical data sheet as variations exist across different brands and models.
QL 60 hammer dimensions
The “QL 60” in drilling refers to a specific DTH (Down-The-Hole) hammer shank style, and the dimensions of QL 60 hammers can vary slightly between manufacturers while adhering to this common interface.
However, here are the typical dimensions you can expect for a QL 60 hammer (excluding the drill bit):
Outside Diameter (OD): This is one of the most consistent dimensions for DTH hammers, as it dictates the minimum hole size the hammer can drill. For a QL 60 hammer, the OD is generally around 140 mm to 148 mm (approximately 5.5 to 5.8 inches). Some models might be slightly larger, especially those designed for heavy-duty or abrasive conditions.
Length (without drill bit, shoulder to shoulder): The overall length of the hammer body, excluding the attached drill bit, is a crucial dimension for handling and fitting within drill string components. Typical lengths range from 1000 mm to 1200 mm (approximately 39 to 47 inches). Some manufacturers might list this as “length from shoulder to shoulder” to ensure consistency.
Weight (without drill bit): The weight of the bare hammer body impacts rig capacity and handling. QL 60 hammers typically weigh between 90 kg to 105 kg (approximately 198 lbs to 230 lbs).
Backhead Thread (Pin): This is the connection point to the drill pipe. For QL 60 hammers, it is almost universally a 3 1/2″ API Regular pin connection.
Drill Bit Shank Type: The hammer is designed to accept drill bits with a QL60 shank, which defines the specific splines and locking mechanism for the bit.
Backhead Wrench Flat Size / Hammer Flat Size: This refers to the flat surfaces on the hammer body used for gripping with wrenches during assembly and disassembly. This can vary, but common sizes are around 101 mm to 114 mm (approximately 4 to 4.5 inches).
It’s important to note that while the QL60 shank is standardized, minor variations in design and specific material thicknesses can lead to slight differences in the overall dimensions and weight among hammers from different manufacturers. Always refer to the specific drill hammer manufacturer’s product data sheet for the exact dimensions of the QL 60 hammer model you are considering.
