Sidavbitare Knipex 78 81 125

Precision diagonal pliers Knipex 78 81 125 designed for ultra-fine cutting tasks in electronics and fine mechanics. The tool features very sharp, ground cutting edges without bevel for flush cutting and precision-shaped tips capable of cutting wires resting on a board from 0.2 mm diameter. The joint uses a stainless steel rivet and cutting edges are additionally induction hardened. The pliers are available in INOX or special tool steel and include an opening spring and opening limiter for controlled operation.

Advantages

The pliers provide ground, very sharp cutting edges for flush and precise cuts, induction-hardened cutting surfaces for extended edge life, and a stainless steel rivet joint for reliable alignment. Precision-shaped tips enable cutting of fine wires on circuit boards from 0.2 mm dia. Extremely smooth movement reduces operator fatigue, while the opening spring and limiter improve handling and repeatability.

Suitable for

• Ultra-fine cutting in electronics and printed circuit board work
• Fine mechanics and watchmaking tasks
• Cutting hard and soft wires with precise, flush results
• Hobbyist and professional precision assembly

Key specifications

• Length: 125 mm
• Weight: approx. 57 g
• Cutting capacity from 0.2 mm diameter on board-mounted wires
• Cutting-edge hardness: approx. 64 HRC
• Material: special tool steel or INOX (stainless option)
• Opening spring and opening limiter included
• Stainless steel rivet joint; induction-hardened cutting edges

How to use

Place the wire as close as possible to the board or the workpiece and position the precision tips around the conductor. Apply steady, even pressure on the handles until the cutting edges shear through the wire to achieve a flush cut. Use the opening spring to ease repeated cuts and the opening limiter to control maximum jaw opening. Maintain a perpendicular cutting angle for best results and avoid twisting or levering the pliers during the cut.

Recommendations

For long service life, keep cutting edges clean and free of solder or adhesive residues; avoid cutting hardened steel beyond the tool’s specified capacity. Periodically check the joint rivet and handle condition; store the pliers dry to prevent corrosion if using the special tool steel version.
