Product Description Drag bit are manufactured from forged high quality alloy steel and PDC cutter insert, plus state of art welding technology and multiple precision heat treatment to provide highest penetration rate and longest lifespan at roughest condition. Drag bits are designed for medium to hard formation and are used in areas that contain a lot of rock and also in the oil field.SizeType PinWeight (lbs.)3 7/8" - 4 3/4"2 3/8" Pin64 7/8" - 5 1/8"2 3/8" Pin75 1/4" - 5 1/2"2 3/8" Pin84 5/8" - 5"2 7/8" Pin105 1/8" - 5 1/2"2 7/8" Pin115 5/8" - 6 1/4"3 1/2" Pin186 1/2" - 6 3/4"3 1/2" Pin197" - 7 1/2"3 1/2" Pin217 5/8" - 8"-12 1/43 1/2" Pin 4 1/2 ,6 5/823 3 wings step drag bits are one piece construction of alloy steel cast with tungsten carbide cutting tips and gauge sides to ensure longer life. It has 3 wings and 3 flushing holes. Compared with 4 wings, 3 wings step drag bits tend to drill faster and aggressive, whereas, are shorter lasting and less durable.3 wings step style drag bits will produce larger cuttings force than chevron style drag bit. Rotary table speed ofstep drag bits should be between 60 and 80 rpm with light weight on bit (WOB).3 wings step drag bits are economical tools when drilling softer geological formations and shallower depths, they are primarilydesigned for soft tomedium formations, such as Clay, Loam, Silt ,Mostsoft-to-medium soilsthat have some moisture, etc. And also step drag bits are recommended for drilling in Mining, Exploration, Environmental, Water well, Geo Exchange, etc.3 wings step drag bitsDiameterThread2 to 17 1/2 inch50.8 to 444.5mmOptionalNote: The diameter and thread showed as above are usual size, other sizes are available upon request.Thread size: 2 3/8'' Reg, 2 7/8'' Reg, 3 1/2'' Reg, 4 1/2'' Reg, 6 5/8'' Reg, 2'' IF, 2 3/8'' IF, 2 7/8'' IF, A Rod, N Rod, AW, BW, NW, AWJ, BWJ, NWJ.Features and Advantages:1. A solid one piece heat treated, 4140 alloy steel body for bit strength & durability;2. CNC threaded machining for proper installation &use;3. Forgings are milled to better seat the carbide inserts.4. Select tungsten carbide inserts 5.5mm thick are standard.5. Relief is hand ground behind carbide inserts for maximum performance. A stepped drag bit is a specialized drilling tool designed for use in geological exploration, mining, and oil and gas extraction operations. It features a unique stepped design with multiple cutting edges or steps arranged in a spiral pattern along its surface, allowing for efficient penetration and removal of rock or sediment layers during drilling operations.The primary function of a stepped drag bit is to create boreholes or wells in various types of subsurface formations, ranging from soft sediments to hard rock formations. Unlike traditional drill bits, which typically have a single cutting edge, stepped drag bits leverage multiple steps or teeth to increase drilling efficiency and productivity. Each step on the bit's surface acts as a cutting element, gradually grinding away at the formation as the bit rotates, thereby facilitating smoother and faster drilling progress.The stepped design of the drag bit enables it to maintain stability and balance while drilling through different types of formations, minimizing vibration, deviation, and the risk of getting stuck or damaged. This stability is crucial for ensuring accurate drilling results and preventing costly downtime or equipment failures. Additionally, the stepped configuration helps to distribute cutting forces evenly across the bit's surface, reducing wear and tear and extending the tool's lifespan.Stepped drag bits are available in various sizes and configurations to accommodate different drilling requirements and formations. They may feature different numbers and arrangements of steps, as well as varying materials and cutting designs, depending on factors such as the hardness of the formation, drilling depth, and desired drilling speed. Some stepped drag bits may also incorporate additional features such as tungsten carbide inserts or diamond-enhanced cutting elements for enhanced performance and durability in challenging drilling conditions.In addition to their effectiveness in drilling operations, stepped drag bits offer advantages in terms of versatility and cost-effectiveness. Their ability to adapt to a wide range of formations and drilling conditions makes them suitable for various applications, including mineral exploration, water well drilling, geotechnical investigations, and oil and gas production. Furthermore, the relatively simple design of stepped drag bits translates into lower manufacturing costs compared to more complex drilling tools, making them an economical choice for both large-scale drilling operations and smaller-scale projects.In summary, stepped drag bits are essential tools for drilling professionals seeking efficient and reliable solutions for borehole creation in diverse geological formations. Their stepped design, multiple cutting edges, and stability characteristics contribute to enhanced drilling performance, productivity, and cost-effectiveness. Whether used in mining, oil and gas exploration, or construction projects, stepped drag bits play a vital role in advancing drilling technology and achieving successful outcomes in challenging drilling environments.
