Knipex 00 20 06 SB 6-Piece Installation Plier Set
Best OverallPros
- Widest jaw range in a mid-size set
- Includes combination, long-nose, and water pump pliers
- Durable chrome vanadium steel construction
Cons
- Higher price point than smaller sets
- No carrying case included
This 6-piece set from Knipex covers the most common clamping tasks for electricians and plumbers. It includes combination pliers, long-nose pliers, and two water pump pliers with jaw capacities ranging from 1.5 to 2.5 inches. Owner reviews consistently praise the smooth adjustment mechanism and the corrosion-resistant finish that holds up well on job sites.
The set lacks a dedicated storage case, which some users note as a minor inconvenience for transport. However, the individual tools are well-balanced and the grips remain comfortable during extended use. For professionals who need a single set that handles wiring, pipe fitting, and general clamping, this is the most practical choice.
Knipex 00 20 05 SB 5-Piece Installation Plier Set
Best for Electrical WorkPros
- Compact and lightweight for tool belts
- Includes high-leverage diagonal cutters
- Excellent grip ergonomics
Cons
- Limited to smaller pipe diameters
- No long-nose pliers included
The 5-piece set is optimized for electrical installations, with tools that fit comfortably in a pouch or tool belt. It includes combination pliers, diagonal cutters, and a water pump plier with a 2.0-inch maximum jaw capacity. Owner reviews highlight the precision cutting edges and the smooth ratcheting action on the water pump plier.
The set sacrifices larger jaw capacities to keep the weight down, which means it is not ideal for plumbing work on 2.5-inch or larger pipes. The lack of long-nose pliers also limits fine wire manipulation. For electricians focused on conduit and cable work, this set provides exactly what is needed without extra bulk.
Knipex 00 20 04 V04 4-Piece Installation Plier Set
Best Budget ValuePros
- Most affordable Knipex clamp set
- Covers 1.5 to 2.5 inch capacity range
- Same steel quality as larger sets
Cons
- No long-nose or diagonal cutters
- Limited to four tools
The 4-piece set is the entry point into Knipex clamp tools without sacrificing build quality. It includes two water pump pliers (10-inch and 12-inch) and two combination pliers, all made from the same chrome vanadium steel used in higher-end sets. Owner reviews note that the 12-inch water pump plier handles 2.5-inch pipes effectively for light plumbing tasks.
The set lacks cutting tools and long-nose pliers, so it is not a complete solution for electrical work. Some users also wish for a storage case at this price point. For DIYers or homeowners who need reliable clamping for occasional repairs, this set delivers the essential tools without the premium cost.
Knipex 00 20 08 SB 8-Piece Installation Plier Set
Best for Heavy-Duty PlumbingPros
- Largest jaw capacity at 3.0 inches
- Includes 8 tools for maximum versatility
- Professional-grade grip and leverage
Cons
- Expensive and heavy
- Overkill for light-duty tasks
The 8-piece set is the most comprehensive Knipex clamp collection, featuring three water pump pliers with capacities up to 3.0 inches, combination pliers, long-nose pliers, and diagonal cutters. This set is designed for professional plumbers who regularly work with large-diameter pipes and fittings. Owner reviews emphasize the exceptional leverage and the secure grip even on slippery surfaces.
The weight and cost of this set make it impractical for casual DIY use or for electricians who need a lightweight belt carry. The additional tools also mean more items to keep track of on a busy job site. For full-time plumbing professionals, the 00 20 08 SB is the definitive heavy-duty choice.
Knipex 00 20 03 V03 3-Piece Installation Plier Set
Best Minimalist KitPros
- Ultra-compact and easy to store
- Lowest cost of any Knipex set
- Includes the essential water pump plier
Cons
- Only three tools limit versatility
- No cutting or long-nose capability
The 3-piece set is the most stripped-down Knipex clamp option, containing a 10-inch water pump plier, a combination plier, and a long-nose plier. It is designed for quick repairs or for users who already own other tools and only need the Knipex clamping core. Owner reviews appreciate the compact size for glovebox or drawer storage.
The limited tool count means you will need additional pliers for cutting wire or gripping larger pipes. The 2.0-inch maximum jaw capacity also restricts use to smaller plumbing fittings. For a backup set or for very light-duty work, this kit is a practical and affordable choice.
What to Check Before Buying a Knipex Clamp Set
Jaw capacity is the most important specification. Knipex sets range from 1.5-inch to 3.0-inch maximum openings. Measure the largest pipe or fitting you will work with regularly and choose a set that exceeds that size by at least 0.5 inches.
Tool count matters for versatility. A 3-piece set covers basic clamping, while 6-piece or 8-piece sets include cutters and long-nose pliers for electrical work. Consider your primary trade: electricians benefit from 5-piece sets with diagonal cutters, while plumbers need 6-piece or larger sets with higher jaw capacities.
Handle length affects leverage. Longer handles provide more clamping force but add weight. Knipex water pump pliers in these sets range from 10-inch to 12-inch handles. For heavy-duty work, opt for 12-inch handles. For portability and tool belt carry, 10-inch handles are sufficient.
Mistakes to Avoid When Choosing a Clamp Set
Buying a set with too small a jaw capacity is the most common error. A 2.0-inch maximum will not grip 2.5-inch plumbing fittings, forcing you to buy additional tools later. Always check the maximum opening against your largest expected workpiece.
Ignoring the tool mix leads to incomplete kits. A 4-piece set without cutters or long-nose pliers will leave you unprepared for wire stripping or fine manipulation. Match the included tools to your typical tasks rather than buying the cheapest option.
Overlooking weight and storage is another mistake. An 8-piece set is heavy for daily belt carry. If you move between job sites frequently, a lighter 5-piece or 6-piece set with a pouch or case will be more practical.
