Precise cutting of fine wires and cables – even soft wires up to Ø1.6 mm
Small dimensions – large cutting capacity
115 mm long and 80 g, this electronics diagonal cutter is extremely compact and lightweight. Unlike diagonal cutters for use in domestic installations, this is a real precision tool. The advantages of the compact dimensions become particularly clear in confined spaces, e.g. for PCBs or precision equipment. Cutting edge hardness approx. 62 HRC lets it cut soft wire up to Ø1.6 mm and hard wire up to Ø0.6 mm. The short pliers head offers strong leverage. It is perfect for power delivery on the cutting edges and controlling manual force.
Zero-backlash box joint. High cut quality and durability
The Knipex 77 11 115 electronics diagonal cutter has a box joint. The inside of both pliers handles is guided. This prevents tilting. Rivets only undergo shearing stress. Result: higher-quality cutting operations, long service life. The tool is oil-hardened, while the cutting edges are induction-hardened to approx. 62 HRC.
Knipex quality standards, corrosion protection and wire catcher
Precision, function and reliability are the key requirements placed on the tool in electronics/precision equipment. The high-grade workmanship of Knipex electronics diagonal cutter 77 12 115 meets these requirements. The meticulously crafted diagonal cutter is ideally suited to sensitive electronic environments, e.g. for work on PCBs.
