KNIPEX Cobra 87 01 250 - 25 Adjustment Positions

KNIPEX Cobra 87 01 250 water pump pliers bring a 10-inch format, serrated jaws, and push-button adjustment to a familiar hand-tool category. The forged chrome vanadium electric steel body is oil-hardened, while the non-slip plastic handles keep the configuration distinct from the multi-component 87 02 250.

Core Specifications and Capacity

The US catalog lists a 10-inch length, 2-inch width, and 3/4-inch height for part number 87 01 250. Its listed weight is 0.745 lb, and the tool has 25 adjustment positions.

The jaws handle round pipe up to 2 inches and hexagonal workpieces up to 1 3/4 inches. A separate US retailer listing identifies the tool's 61 HRC teeth, box-joint design, self-locking action, pinch guard, and DIN ISO 8976 standard.

Materials and Adjustment System

KNIPEX specifies chrome vanadium electric steel that is forged and multi-stage oil-hardened. The gripping surfaces are serrated, the jaws are polished, and the outer finish is gray atramentized.

The push button sets the opening directly at the workpiece, while the box-joint construction uses a double guide for stability. The 87 01 250 is not the automatic Cobra...matic 87 11 250, which adds a spring-assisted adjustment system and carries a different part number.

US Price and Position

Home Depot lists model 87 01 250 at $38.19 as of 09/24/2026. The US listing describes the tool as a heavy-duty 10-inch Cobra plier with 61 HRC teeth.

That price places the 87 01 250 in the standard single-tool range for professional-style water pump pliers. The 250 mm tool fits plumbing, mechanical maintenance, and general shop work where a 2-inch round-pipe capacity matters more than compact-jaw access.

Best Fit for the Tool

The KNIPEX Cobra 87 01 250 is a conventional push-button water pump plier with a broad 2-inch round-pipe capacity, 25 positions, and plastic-coated handles. Its 10-inch body provides more reach than smaller 7 1/4-inch Cobra models, while the 12-inch 87 01 300 offers a larger format.

The practical limit is the manual adjustment system: the user positions the jaw and closes it rather than relying on the automatic spring mechanism of the Cobra...matic. For users who need insulated electrical protection, the non-insulated 87 01 250 is the wrong configuration.
