Tongue-and-groove pliers Knipex 83 60 015

The Knipex 83 60 015 tongue-and-groove pliers are a heavy-duty tool for gripping and turning pipes, fittings and hexagonal nuts up to 60 mm in diameter. At 420 mm overall length and approximately 1.47 kg weight, these pliers deliver strong leverage and stable handling for plumbing, mechanical and assembly tasks. The adjustable tongue-and-groove joint offers multiple gripping positions while the robust steel construction and precision-machined jaws ensure consistent contact and long service life.

Advantages

These tongue-and-groove pliers provide secure grip on round, hexagonal and irregular surfaces thanks to accurately profiled jaws and a positive locking mechanism. The 420 mm length increases torque while preserving user control, and the rugged build minimizes deformation under load. The adjustable joint enables quick size changes without tools, and the ergonomic handles improve comfort during repeated use.

Suitable for

• Plumbing work: tightening and loosening pipe fittings and hoses
• Mechanical maintenance: holding and turning shafts, nuts and fasteners
• HVAC and installation tasks where access and leverage are required
• General workshop and construction use for gripping irregular objects

Key specifications

• Maximum grip diameter: up to 60 mm
• Overall length: 420 mm
• Approximate weight: 1.47 kg
• Adjustable tongue-and-groove joint with multiple positions
• Material: hardened tool steel with precision-machined jaws
• Handle design: ergonomic for improved control

How to use

Position the jaws around the workpiece and select the appropriate tongue-and-groove setting so the jaws sit squarely on the surface. Apply steady hand force to turn or hold the component, using the 420 mm leverage to reduce effort on larger diameters. Reposition the joint as needed to accommodate different sizes; avoid using the pliers as a hammer or prying tool to prevent damage. After use, clean off debris and lightly lubricate the joint to maintain smooth adjustment.

Usage recommendations

Use these pliers for gripping and turning tasks within the specified diameter range. For precision torque or torque-limited fastenings, use a torque wrench. For electrical work, ensure tools and surroundings are de-energized and insulated as required. Store in a dry place and perform periodic inspection for wear or damage.
