Plastic pipe cutting shears

Types of plastic pipe cutting shears

There are various kinds of plastic pipe cutting shears that cater to different kinds of needs. Here are some of the most common types:

• Ratchet plastic pipe cutting shears

  These shears utilize a ratchet mechanism to cut pipes. The handle has a ratchet mechanism that allows for one-handed operation by moving the handle back and forth. As the handles are closed, a pawl engages and advances a toothed wheel, driving the cutting blade through the pipe. The blade is sharp and curved to make clean, quick work of even thick PVC or CPVC pipes. An adjustable bolt accommodates various pipe sizes. Ratchet pipe cutters are efficient tools that simplify cutting tasks by leveraging their mechanical advantage.

• Single-blade pipe cutters

  Single-blade plastic pipe cutters consist of a cutting wheel and an opposing jaw. Squeezing the handles brings the cutting wheel down onto the pipe, and a ratcheting action allows repeated squeezes to make deeper cuts. They are compact and suited for cutting smaller diameters of plastic, copper, PEX, or PVC pipe in tight spaces. Their simple design makes them easy to use and maintain. However, they may require more effort to cut thick or large pipes than other types of cutters with geared mechanisms.

• Bypass pipe cutters

  Bypass plastic pipe cutting shears feature two blades that work like scissors. One blade is stationary, while the other passes by it when the handles are squeezed. This cutting action is well-suited for cutting plastic, copper, or PVC pipe. Bypass cutters provide a clean cut and are ideal for cutting pipe in tight spaces. However, they may struggle with thicker or larger pipes. Regular blade sharpening and maintenance are important for optimal cutting performance.

• Heavy-duty pipe cutters

  Heavy-duty plastic pipe cutting shears are designed for cutting large diameter plastic, copper, or PVC pipes. They have longer handles that provide more leverage and a ratchet mechanism to require less effort per cut. Replacement wheels are available for long-term use. Adjustments accommodate different pipe sizes. Some models include a blade lock for safety. These cutters are suitable for continuous cutting of thick or big pipes and offer durability and cutting power.

How to choose plastic pipe cutting shears

  Plastic pipe cutting shears are more efficient and require less cutting force. Some models have a ratchet mechanism that allows for more accessible cutting by applying a step-by-step force to the pipe. Buyers should check the mechanism's operation to ensure it works smoothly and efficiently.

• Safety Features:

  Safety features are also essential to consider when purchasing plastic pipe cutting shears. Some models have a locking mechanism that locks the shears closed when not in use, preventing accidental cuts. Buyers should check the safety features of the shears to ensure they are safe and practical.

• Brand and Warranty:

  The brand and warranty of the plastic pipe cutting shears are essential factors that buyers should consider when purchasing. Well-known brands usually have better quality and more reliable shears. In addition, the warranty period indicates the manufacturer's confidence in the product's durability, so buyers should choose models with longer warranty periods.

How to use, install, and product safety

How to use

• Open the Shears: The first step is to open the cutting tool plastic pipes by rotating the handles outward. This action will separate the two jaws of the shears, creating a gap wide enough to accommodate the pipe intended for cutting.
• Position the Pipe: Next, the user must place the pipe that needs cutting within the opened jaws of the shears. It is essential to ensure that the pipe is positioned correctly and snugly against the cutting blade to guarantee a clean and precise cut.
• Close the Shears: After positioning the pipe, the user must squeeze the handles together. This motion will bring the jaws of the shears back together, effectively clamping down on the pipe.
• Cutting Action: Continuing to apply pressure to the handles will engage the cutting blade, cutting the pipe. The mechanism within the shears will amplify the user's hand strength, allowing for a clean and effortless cut through the plastic pipe.

Installation and Tips

• One Cut: For the best results, the user should make a single, smooth cut to prevent fraying or uneven edges. This will ensure a clean and precise cut of the pipe.
• Fraying: If fraying occurs, it is recommended to use a file or deburring tool to smooth out the edges of the cut pipe. This step is crucial when working with internal fittings because rough edges can hinder the fitting's ability to connect smoothly and might cause leaks in the plumbing system.
• Cutting Thick Pipes: When cutting thicker plastic pipes, it may be necessary to cut the pipe in half to achieve a clean and precise cut. This approach can be beneficial in ensuring that the cut is even and that the pipe can fit snugly into fittings without any obstruction.

Product Safety

• Wear Safety Gear: Always wear safety goggles to protect the eyes from plastic shavings that may fly out when cutting the pipe. This precaution is crucial for ensuring the safety of the eyes and preventing any injury that could result from cutting operations.
• Check the Shears Before Use: Always inspect the cutting plastic pipe tool before using it to ensure that the blades are aligned correctly and the locking mechanism is functioning properly. This check is crucial for ensuring that the tool operates safely and effectively.
• Cut Away from Body: Always cut the plastic pipe away from the body to prevent injury. This safety measure is essential to avoid accidents that could occur due to slipping or misdirected cutting.
• Stable Position: Always maintain a stable position when cutting the pipe to prevent any loss of balance or control over the cutting action. This control is essential for ensuring a clean cut and preventing accidents that could occur due to sudden slips or misdirected cutting.
• Proper Pipe Support: Always support the pipe adequately during the cutting process to prevent any bending or flexing, which could lead to an uneven cut or damage to the pipe. Proper support ensures a smooth cutting process and prolongs the life of the cutting tool.
