Self-Adjusting Insulation Stripper - Knipex - 12 40 200

The Knipex 12 40 200 can handle wire cross-sections from 0.03 to 10.0 mm², which corresponds to AWG 32 to 8.

Yes, it is designed to work effectively with single, multiple, and fine-stranded conductors.

The cutting depth can be adjusted manually using the integrated setting mechanism on the tool, typically a screw or dial, to match the thickness of the insulation material.

Yes, the stripper is suitable for wires with plastic or rubber insulation. The adjustable cutting depth helps accommodate different material thicknesses.

Yes, it includes a built-in wire cutter for copper and aluminum wires, capable of handling stranded wires up to 10.0 mm² and single-stranded wires up to 6.0 mm².

The Knipex 12 40 200 has a length of 200mm.

Yes, the stripping blades and clamping jaws are designed to be easily replaceable, allowing for maintenance and extending the tool's service life.

Check if the stripping blades are worn or damaged. Clean the blades and jaws. Ensure the cutting depth is correctly adjusted for the insulation type and thickness. If blades are damaged, they may need replacement.

Verify the tool is properly adjusted to the wire's cross-section. For very fine wires, ensure the automatic adjustment is functioning correctly. If the issue persists, the wire's insulation might be unusually thick or tough, requiring manual adjustment of cutting depth or a different tool.

Clean the moving parts of the stripper. Check for any debris caught in the mechanism. Lubricate the pivot points sparingly with a light machine oil if necessary, ensuring excess oil is wiped away.

Inspect the wire cutter blades for damage or dullness. Ensure you are not exceeding the specified maximum wire diameter for the cutter (6mm single-stranded, 10mm stranded).
