Types of cutters: O-flute single flute end-mills, carbide cutters, adjustable tube cutters
A thermoplastic tube cutter is a tool used to cut thermoplastic tubing. One such cutter is the MettleAir Compact Tube Cutter for Thermoplastic Tubing TC-01, which provides square, clean cuts of thermoplastic tubing (vinyl, nylon, polyethylene, polyurethane) for up to 1/2" OD.
There are several types of cutters that can be used for thermoplastics: O-flute single flute end-mills, carbide cutters, and adjustable tube cutters.
O-flute single flute end-mills have a unique geometry that makes them highly efficient for cutting thermoplastics. The high rake angle and low helix allow for cutting a range of materials, including acrylic, polycarbonate, ABS, PVC, and sheet polymers, without burrs or edge fractures and leaving a clean surface finish. The shank diameter of these cutters is typically 0.2500 inches (6.35 mm), with a maximum depth of cut that varies by diameter.
Carbide cutters, made from premium-grade tungsten carbide, are another option for cutting thermoplastics. While specific details on this type of cutter are limited, they are likely to have similar applications to O-flute cutters.
Adjustable tube cutters, such as those available from brands like Husky, Milwaukee, and RIDGID, are also suitable for cutting pipes and tubes made from various materials, including PVC. These cutters often have adjustable features to accommodate different tube diameters and provide precise cuts.

A thermoplastic tube cutter is a tool designed to cut through thermoplastic tubes. Thermoplastics are plastics that can be moulded and remoulded upon the application of heat and pressure. Tube cutters are available in various sizes and designs, with some being more suitable for certain materials than others.
Vinyl, also known as polyvinyl chloride (PVC), is a type of plastic that is strong, durable, and flexible. It is often used in tubing applications such as plumbing, electrical insulation, and medical devices. Vinyl tubing can be cut with a variety of tube cutters, including those designed for plastic tubing in general and vinyl tubing specifically.
Nylon is a synthetic polymer that is known for its durability, strength, and flexibility. It is commonly used in applications such as ropes, fabrics, and tubing. Nylon tubing is often used in automotive, industrial, and hydraulic systems. Tube cutters designed for plastic tubing can typically cut through nylon tubing as well.
Polyethylene is a lightweight and flexible thermoplastic polymer. It has high impact strength and is resistant to chemicals and moisture. Polyethylene tubing is commonly used in industries such as packaging, agriculture, and healthcare. Tube cutters designed for plastic tubing can generally be used to cut polyethylene tubing.
Polyurethane is a versatile polymer that combines the flexibility of rubber with the toughness and durability of metal. It has excellent resistance to abrasion, impact, and chemicals. Polyurethane tubing is used in a variety of applications, including hydraulic systems, medical devices, and fuel lines. Tube cutters designed for polyurethane tubing can provide clean and precise cuts.
PEEK (Polyether Ether Ketone) is a semi-crystalline, high-performance engineering thermoplastic. It offers exceptional mechanical strength, rigidity, and dimensional stability. PEEK tubing is commonly used in applications requiring high-temperature resistance, chemical compatibility, and mechanical durability. PEEK tubing can be cut with specialised tube cutters or those designed for plastic tubing in general.
FEP (Fluorinated Ethylene Propylene) is a semi-clear, flexible thermoplastic tubing that maintains its strength and benefits across a wide range of temperatures and conditions. FEP tubing is known for its high heat resistance, chemical resistance, and ease of cleaning. It is commonly used in applications such as medical devices, chemical processing, and food contact. FEP tubing can be cut with tube cutters designed for plastic tubing, and some cutters have specific compatibility with FEP.
PFA (Perfluoroalkoxy Alkane) is a fluorocarbon-based polymer with similar characteristics to FEP. It offers excellent chemical resistance, temperature stability, and non-stick properties. PFA tubing is commonly used in applications such as chemical processing, semiconductor manufacturing, and food processing. PFA tubing can be cut with certain tube cutters, including those designed for plastic tubing and those with specific compatibility.
Tefzel, or ETFE (ethylene tetrafluoroethylene), is a modified copolymer of ethylene and tetrafluoroethylene. It exhibits excellent physical toughness, radiation resistance, chemical resistance, and UV resistance. Tefzel is commonly used in applications requiring mechanical toughness, chemical resistance, and extreme temperature changes. Tube cutters that are compatible with Tefzel tubing can provide clean and precise cuts.

Compatible tube sizes: OD sizes 1/8 to 1/2
A thermo-plastic tube cutter, also known as a hot knife cutter, is a hot blade used to cut, shape, and seal synthetic materials. It is a highly effective tool for cutting through a wide range of materials, including carpets, rope, foam, and gaskets. Thermo-plastic tube cutters are also ideal for cutting plastic tubing.
One such cutter is the Plastic Tubing Cutter (catalog number A-327), which is designed specifically for semi-rigid and rigid polymer tubing. It features built-in guide holes for both 1/16 and 1/8-inch OD tubing and offers a flat, 90-degree, burr-free cut. It is compatible with tubing sizes from 1/8-inch to 1/2-inch OD, providing durability, reliability, and ease of use.
The cutter's replacement blades are sold separately, and it can cut through polymers such as PEEK, FEP, PFA, and Tefzel. This tubing cutter is spring-loaded and designed with a guillotine-style cutting mechanism. It is easy to use and provides precision and durability.
When using a thermo-plastic tube cutter, it is important to ensure that the tool is plugged in and heated up before beginning to cut. The material to be cut should be laid out on a flat surface, and the room should be well-ventilated to avoid inhaling any fumes.

Blade replacement: Replacement blades sold separately
A thermoplastic tube cutter, also known as a thermocutter, is a hot blade used to cut, shape, and seal synthetic materials. It is a highly effective tool for cutting through a wide range of materials such as carpets, rope, foam, and gaskets. The blades of a thermoplastic tube cutter heat up instantly, and the temperature can be adjusted using a thumb wheel.
When it comes to blade replacement, it's important to note that replacement blades are sold separately. While the process of replacing blades may vary slightly depending on the specific model of the thermoplastic tube cutter, there are some general steps that are typically involved. Firstly, identify the black piece at the back of the knife, which is usually the slider that holds the blade in place. By pulling on this black piece, you can release the slider and access the blade for replacement. After removing the old blade, follow the same steps in reverse to insert the new blade. Ensure that the black piece is securely placed back to prevent the slider from moving too far back and maintain the blade's stability.
Some manufacturers, such as Assembly Supplies Co., offer a range of replacement blade styles with varying lengths and thicknesses, including custom blades. It is worth noting that some thermoplastic tube cutters may include replacement blades with the initial purchase, providing convenience and ensuring a sharp cutting edge.
Additionally, proper care and maintenance of the thermoplastic tube cutter blades are essential. Regularly inspect the blades for any signs of wear or dulling, and consider resharpening or replacing them as necessary to maintain optimal performance. It is also important to follow safety precautions, such as working in a well-ventilated area, to avoid inhaling any fumes produced during the cutting process.
By following these guidelines and staying attentive to the specific instructions provided by the manufacturer of your thermoplastic tube cutter, you can effectively replace the blades and maintain the tool's performance and longevity.
