How to choose
Pipe Cutting Capability
The Knipex 90 31 02 SBA TubiX is designed specifically for pipe cutting applications. It features a magnesium body and incorporates a QuickLock mechanism for rapid adjustment, which streamlines the process of sizing the tool to the pipe diameter. For users working with plastic piping specifically, the 90 22 10 BK Bix cutter provides an alternative option. This model is engineered to cut plastic pipes between 20 and 50 mm without creating shavings and includes two spare blades. Selecting the right tool depends on whether you require a versatile metal pipe cutter or a specialized solution for plastic pipe installation tasks.
Maintenance and Longevity
Long-term tool maintenance is essential for consistent performance. The TubiX 90 31 02 SBA is supported by the 90 39 02 V03 replacement set, which includes five cutting wheels and needle bearings. This maintenance kit is compatible with both the 90 31 02 SBA and the 90 31 03 BKA models. By utilizing these replacement components, users can extend the operational life of their pipe cutter without needing to purchase an entirely new unit. Keeping spare cutting wheels on hand ensures that the tool remains sharp and effective for ongoing professional or workshop plumbing projects.
Specialized Precision Tools
Beyond pipe cutting, Knipex offers precision hand tools for specific mechanical tasks. The 46 21 A31 precision circlip pliers are designed for external circlips on shafts ranging from 1 37/64" to 3 15/16". These 90-degree angled pliers are distinct from the cutting tools in the lineup, focusing on assembly and disassembly rather than material removal. While the TubiX is built for pipe sizing, the 46 21 A31 provides the necessary geometry for working with external retaining rings in tight spaces, highlighting the diversity of the Knipex tool catalog for specialized workshop requirements.
Integrated Features
Design efficiency is a hallmark of the TubiX 7.25" pipe cutter. It features an integrated deburring tool, which allows users to smooth pipe edges immediately after cutting. This consolidation of functions minimizes the need to carry separate deburring implements. Similarly, the 90 22 10 BK Bix cutter emphasizes clean operation by cutting plastic pipes without producing shavings. When evaluating these options, consider whether your workflow benefits more from an all-in-one cutter and deburrer, like the TubiX, or a specialized, chip-free cutting tool designed specifically for plastic materials.
Tool Set Versatility
For general workshop needs, Knipex provides multi-piece sets such as the 9K 00 80 12 US 3-piece long nose tool set. This kit includes the 38 31 200, 38 71 200, and 38 91 200 models, offering varying configurations for reaching and gripping in restricted areas. While these tools differ significantly from the TubiX pipe cutter or the Bix plastic cutter, they represent the breadth of the brand's hand tool offerings. Incorporating these long nose pliers into a toolkit alongside dedicated pipe cutting equipment provides a more comprehensive setup for plumbing, maintenance, and general mechanical assembly.
Frequently asked questions
What is the primary function of the Knipex 90 31 02 SBA TubiX?

Its construction features a magnesium body and an integrated deburring tool, making it a comprehensive solution for sizing and preparing pipes. It is designed for efficiency, allowing users to quickly lock the tool onto a pipe and perform cuts while utilizing the onboard deburring feature to finish the edges.
Are replacement parts available for the TubiX pipe cutter?
Yes, replacement parts are available for the 90 31 02 SBA. The 90 39 02 V03 replacement set is specifically designed for this model and the 90 31 03 BKA. This set includes five cutting wheels and the necessary needle bearings to maintain the tool's performance. Having this set ensures that when the original cutting wheels wear down from regular use, they can be replaced easily to restore the tool's effectiveness.
How does the 90 22 10 BK Bix cutter differ from the TubiX?
The 90 22 10 BK Bix cutter is specialized for plastic pipes with a diameter range of 20 to 50 mm. Unlike the TubiX, which is a general-purpose pipe cutter, the Bix is engineered to cut plastic without creating shavings. It also comes with two spare blades included. It is a more focused tool for plumbing tasks involving plastic piping, whereas the TubiX is built for broader pipe-cutting versatility.
Can the 46 21 A31 pliers be used for cutting pipes?
No, the 46 21 A31 is a pair of precision circlip pliers designed for external use on shafts between 1 37/64" and 3 15/16". These pliers feature a 90-degree angled tip for specific assembly tasks involving retaining rings. They are not intended for cutting pipes or any other material. For pipe cutting, the TubiX 90 31 02 SBA or the Bix 90 22 10 BK should be used instead.
What is included in the 9K 00 80 12 US long nose tool set?
The 9K 00 80 12 US long nose tool set is a 3-piece collection containing the 38 31 200, 38 71 200, and 38 91 200 models. These tools are designed for gripping and reaching in tight spaces, offering different configurations for varied mechanical applications. This set serves as a general-purpose addition to a workshop, complementing the specialized cutting and deburring tools like the TubiX or the Bix cutter.
Bottom line
For professionals and DIY enthusiasts requiring a reliable, high-performance pipe cutter, the Knipex 90 31 02 SBA TubiX stands out as the strongest fit. With a 4.7-star rating and a robust magnesium body, it combines durability with the convenience of a QuickLock mechanism and an integrated deburring tool. It excels in versatility, particularly when paired with the 90 39 02 V03 replacement set for long-term maintenance. While other Knipex offerings like the 9K 00 80 12 US tool set or the 46 21 A31 circlip pliers are excellent for their respective mechanical tasks, the TubiX remains the superior choice for those prioritizing efficient pipe preparation and cutting in a single, well-engineered handheld unit.
Deciding between these Knipex tools depends entirely on your immediate project requirements. Choose the TubiX 90 31 02 SBA if you need a durable, general-purpose pipe cutter with integrated deburring. If your work is exclusively focused on plastic pipe installation, the 90 22 10 BK Bix cutter is the better choice for its clean, shaving-free performance. If your workshop needs are more mechanical, such as handling external circlips or reaching into tight areas, prioritize the 46 21 A31 pliers or the 9K 00 80 12 US long nose set. Always match the tool's specific design intent to your material type and task to ensure the best results.
