TNI-U TU-109 Wire Cutter with Angled Head

The TNI-U TU-109 Wire Cutter is a compact 5-inch cutting tool designed for electronics repair, circuit assembly, model making, and light-duty workshop applications. Its precision cutting edges make it suitable for trimming thin wires, electronic component leads, cable ties, and small plastic parts.

Unlike conventional straight-head cutters, the TU-109 features a cutting head positioned at an approximately 45-degree angle. Therefore, it provides improved access to components and wires located inside narrow spaces. This design is particularly useful when trimming resistor, capacitor, LED, and diode leads close to a printed circuit board.

Comfortable Spring-Loaded Wire Cutter

The built-in return spring automatically opens the handles after every cut. As a result, the user can perform repeated cutting operations quickly and with less hand movement. This feature makes the TNI-U TU-109 Wire Cutter practical for electronics technicians, students, makers, and maintenance professionals.

In addition, the yellow non-slip handles provide a comfortable and controlled grip. The lightweight body also reduces fatigue during extended assembly or repair tasks. Furthermore, its compact 130mm size allows it to fit easily inside a small toolbox, electronics kit, technician’s bag, or workshop drawer.

Recommended Applications

The TNI-U TU-109 can be used for:

• Cutting thin copper and soft electrical wires
• Trimming electronic component leads
• PCB assembly and soldering work
• Mobile phone and electronics repair
• Cutting small cable ties
• Trimming soft plastic sprues
• Robotics and Arduino projects
• Jewelry and craft applications
• Model making and general DIY work

Usage and Safety Instructions

For a cleaner cut, position the wire near the center of the cutting edges and apply steady pressure. Always disconnect wires and electronic devices from their power source before cutting. In addition, wear protective glasses because trimmed component leads can move suddenly.

However, this precision cutter is not designed for thick electrical cables, hardened steel wire, nails, screws, bolts, or heavy mechanical cutting. Using it on unsuitable materials may damage or deform the cutting edges.

Although the handles have a plastic coating, the tool does not carry a certified electrical insulation rating. Therefore, never use the TNI-U TU-109 Wire Cutter on live electrical circuits.

Finally, clean the cutting head after use and store the tool in a dry place. A small drop of light machine oil on the moving joint can help maintain smooth operation and extend its service life.
