Diagonal cutter BAHCO RX 8150, RX series oval head, length 138 mm, jaw width 1.25 cm

BAHCO diagonal cutter RX 8150 is a compact oval-head diagonal plier with a 138 mm overall length designed for precise close cutting of wires and small components. The tool features a short 13 mm jaw and 12.5 mm jaw width, offering controlled access in crowded assemblies and on printed circuit boards. With a lightweight construction of approximately 73 g and ERGO™ handle geometry, this diagonal cutter balances reach and maneuverability for electrical, electronics and general workshop tasks that require accurate flush cuts.

Advantages

The RX 8150 provides consistent cutting performance thanks to numerically controlled machine grinding that maintains precise edge angles and contact. Its induction-hardened cutting edges (63–65 HRC) and screw joint reduce wear and friction while ensuring alignment of the blades. ESD-safe two-component handles deliver a comfortable, non-slip grip on a rigid polypropylene core, while the adjustable bio spring smooths the working cycle and can be set to three positions or removed. A phosphate finish and high-performance alloyed steel construction contribute to corrosion resistance and durability.

Suitable for

• Cutting copper and soft wires in electrical installation and maintenance
• Wire harness assembly and repair
• Precision trimming and component lead cutting on printed circuit boards
• General workshop tasks requiring flush, close cuts in confined spaces

How to use

Position the diagonal cutter so that the object to be cut is as close to the joint as possible for the cleanest, easiest cut. For PCB work or tight assemblies, use the oval head to access confined areas and align the blades perpendicular to the wire or lead. Apply steady, controlled pressure until the cut is complete. The adjustable bio spring can be set to a preferred tension or removed for manual operation. After use, wipe the cutting edges clean and store the tool in a dry place to preserve the phosphate finish and edge hardness.

Usage recommendations

Use the RX 8150 only within its specified cutting capacity, particularly for copper wire sizes indicated. Avoid cutting hardened steel, piano wire, or materials outside the recommended range to prevent premature edge damage. For safe handling during electronics work, ensure ESD precautions are observed and periodically check blade alignment and spring function to maintain optimal performance.
