Diagonal cutter BAHCO RX series Oval head — length 135.5 mm, jaw width 1 cm, weight 70 g

BAHCO RX series diagonal cutter with an oval head is a compact precision cutting tool measuring 135.5 mm in total length. Designed for close, accurate cuts in electrical, electronics and general maintenance work, this diagonal cutter features a 1.05 cm jaw length, a 1 cm jaw width and a lightweight 70 g construction that supports frequent use without excessive hand fatigue.

Advantages

The cutting edges are induction-hardened to 63–65 HRC and machine-ground to precise angles, ensuring consistent contact and long life. A screw joint reduces friction and maintains perfect alignment of the cutting edges. ERGO™-designed handles combine a rigid polypropylene core with a two-component thermoplastic surface for a comfortable, secure grip; ESD-safe materials reduce static risk for sensitive electronics. A removable bio spring provides controlled opening tension with three settings to suit different working rhythms. The phosphate finish and high-performance alloyed steel construction improve durability and corrosion resistance.

Suitable for

• Cutting copper and soft metal wires in electrical installations and wiring harnesses
• Trimming component leads and wires on printed circuit boards (PCB assembly)
• Fine mechanical maintenance and precision electronics repair
• Tasks requiring flush, micro-bevel or ultra-close cuts in confined spaces

How to use

Position the oval head diagonal cutter close to the workpiece so the cutting edges fully enclose the wire or component lead. Apply steady pressure to the handles until the cut is complete, avoiding twisting motions that can damage the edges. Use the bio spring setting that matches your preferred opening tension or remove it if manual control is preferred. For PCB work, hold components steady and cut close to the board to obtain a flush finish; for wiring harnesses, use multiple small cuts rather than excessive force on a single cut to preserve edge life.

Usage recommendations

Keep cutting edges clean and free of debris; avoid cutting hardened steel, piano wire, or materials beyond the specified cutting capacity to prevent edge damage. Periodically check the screw joint for secure alignment and, if necessary, have the edges professionally sharpened. Store the tool in a dry place and apply light lubrication to the joint if stiffness occurs.
