In a nutshell
The right choise for
With the Knipex 12 19 06 spare blade set, you quickly restore the original stripping precision of your Knipex 12 12 06 precision insulation stripper. Replacing worn blades eliminates conductor damage and prevents messy, torn insulation edges. Crafted from oil-hardened special tool steel, these shaped blades deliver exceptional wear resistance for demanding, long-term use. They cut cleanly and smoothly through tough insulating materials including PTFE, silicone, Radox, Kapton, and rubber across conductor cross-sections from 0.14 to 6.0 mm². This allows you to maintain flawless wire preparation during critical harness assembly without needing to invest in a completely new tool.
