KNIPEX Cobra Pliers Set 00 19 55 S8 2 Piece

Professional Pliers Set for Fleet Maintenance

The KNIPEX Cobra Pliers Set 00 19 55 S8 contains two pieces designed for fleet and plant maintenance tasks. Self-locking functionality grips pipes and nuts securely without slipping, while the push-button adjustment allows one-hand operation directly on the workpiece. An integrated pinch guard prevents finger injuries during use. The set suits professional technicians who need reliable, adjustable gripping tools for daily heavy-duty work.

Sustained Grip Performance Under Load

The box-joint design employs a bilateral guide that withstands large loads without deformation during extended use. Induction-hardened teeth at approximately 61 HRC retain their profile and biting force over long periods, reducing wear compared to standard teeth. Oil-hardened and tempered chrome vanadium electric steel construction resists fatigue and maintains structural integrity across repeated high-torque applications. Minimal hand force is required to maintain clamping pressure, lowering operator fatigue during continuous jobs.

61 HRC Tooth Hardness Determines Wear Life

The single specification that decides whether this set is the right part is the induction-hardened gripping teeth rated at approximately 61 HRC. This hardness level ensures the teeth resist rounding and maintain secure grip on hardened fasteners and pipes through thousands of cycles. If the application involves softer materials or only occasional use, lower-hardness alternatives may suffice, but for daily fleet maintenance on tough components, this hardness is the decisive factor.
