Precision stripping pliers for form-fitting stripping of difficult-to-remove insulating materials such as PTFE, silicone, Radox, Kapton, and rubber, including multi-layered insulation. A second pair of blades securely holds the remaining insulation in place. Interchangeable form blades are precisely matched to the respective conductor cross-section. The tool has capacities for half-moon, square connection, stepped square, triangular, and clamping ranges for hexagonal, round, and square.
