Basic Specifications

• Name: 295 mm High Performance Oil Drilling Tools PDC Bit / Rock Bit / Tricone Bit

• Diameter: 295 mm

• Blade Number: 5

• Body Type: Steel Body

• No. of Nozzles: 5

• Primary Cutter Size: 1613 (16 mm diameter, 13 mm height)

• Connection Thread: 6 5/8″ API Reg Pin

The bit’s large diameter of 295 mm makes it ideal for primary borehole drilling in large-scale operations. Its five-blade design provides an optimal balance between aggressive cutting action and structural stability. The steel body construction adds strength and resistance to mechanical impact and deformation under tough downhole conditions.

Cutting Technology

The bit features premium 1613 PDC cutters arranged strategically across the blades to ensure even wear and superior cutting performance. These diamond-enhanced cutters offer exceptional resistance to wear, heat, and impact, making them ideal for abrasive formations such as sandstone and dolomite. The PDC cutters maintain sharp cutting edges over extended periods, reducing the need for frequent bit replacement and minimizing downtime.

Hydraulic System and Nozzle Configuration

This bit includes five nozzles, expertly positioned to optimize the hydraulic efficiency of the bit. The fluid jets from the nozzles help:

• Clean the bit face continuously

• Remove rock cuttings efficiently

• Cool the cutters during operation

• Prevent bit balling, especially in sticky formations like marl and clay

Efficient fluid dynamics also enhance rate of penetration (ROP) and help extend the service life of the bit.

Operating Parameters

• Rotational Speed (RPM): 60 to 260

• Weight on Bit (WOB): 30 to 140 kN/mm

The bit supports a wide operating range, allowing it to be customized for various drilling rigs and formation types. When used with downhole motors (PDM), the bit achieves smoother rotation and more efficient energy transfer, especially useful in directional or deviated drilling.

Recommended Formations

This PDC bit is specifically engineered for medium to medium-hard formations, including:

• Dolomite: A high-compressive strength rock that requires sharp, durable cutters

• Limestone: Particularly abrasive and brittle in nature

• Anhydrite: Often found in salt sections, known for its hardness and abrasive quality

• Sandstone: Especially quartz-rich types, which can be tough on cutting structures

Its design ensures it can also handle formation transitions, reducing bit wear during interbedded zones.

Compatibility with Downhole Motors (PDM)

When used with Positive Displacement Motors, this bit excels in directional and horizontal drilling. The steady, high torque output of PDMs matches well with the bit’s cutting profile, making it suitable for operations requiring high precision and control.

---

Applications

This PDC bit is widely used in:

• Oil and gas well drilling

• Geothermal energy exploration

• Water well drilling

• Mineral extraction and geotechnical projects

Its robust construction and efficient design make it a reliable choice for demanding drilling conditions, from soft sticky clays to tough abrasive sandstones.
