Knipex betonwerkerstang 12 mm kop model 99 00 220K12EAN – tang voor het snijden van betonspijkers

Knipex Concreters Nippers 12 mm Head model 99 00 220K12EAN are purpose-built pliers for cutting and removing concrete nails, hardened pins and similar fasteners used in construction and renovation. The tool features a compact 12 mm cutting head that provides close access to nail heads and embedded fasteners. Designed by Knipex for professional environments, these nippers combine precise cutting geometry with robust leverage to handle hardened steel without excessive effort.

Advantages

The 12 mm head allows working close to surfaces and into narrow gaps while maintaining controlled cutting action. Hardened cutting edges and a solid joint deliver long service life and consistent performance on tough materials. Ergonomic handles provide grip and control during repeated use on site. The tool’s design balances cutting power with maneuverability, enabling clean cuts on concrete nails and similar fasteners with minimal disturbance to surrounding material.

Suitable for

• Cutting and removing concrete nails and hardened pins
• Renovation and demolition tasks where embedded fasteners must be removed
• Carpentry and formwork removal after concrete setting
• On-site repair work in construction and civil engineering

Key specifications

• Cutting head width: 12 mm for close-access cutting
• Material: hardened cutting edges suitable for hardened steel fasteners
• Finish: robust surface treatment for corrosion resistance
• Handle: ergonomic design for improved grip and control
• Joint: solid riveted joint for stable leverage and durability

How to use

Position the nipper’s 12 mm head so the cutting edges engage the visible portion of the concrete nail or pin. Apply steady, even pressure on the handles to close the cutting edges around the fastener, taking care to maintain alignment with the nail to avoid slipping. For embedded or stubborn nails, work incrementally: cut a portion, adjust position and repeat until the fastener is removed. Use the compact head to access nails close to the concrete surface or within tight gaps. Keep hands clear of the cutting zone and ensure a stable stance when applying force.

Recommendations

Use eye protection and gloves when cutting hardened nails. Inspect the cutting edges regularly and replace the tool if chips or excessive wear appear. For large diameter or heavily deformed fasteners, consider pre-drilling or using appropriate extraction tools in combination with the nippers to reduce risk of tool overload.
