WETOLS 3-in-1 Rivet Nut Tool Kit WE-890 — Rivet Gun & Reamer, 5 Heads, 6 Mandrels, Carry Case

The WETOLS WE-890 is a compact 3-in-1 hand tool that functions as a rivet nut setter, pop rivet gun and reamer, supplied with mandrels, rivets, rivet nuts and a blow-molded case for portable professional use.

Designed for mechanics, fabricators and DIYers who need a single handheld tool to handle blind rivets, rivet nuts and light reaming tasks, this kit combines three functions into one ergonomically shaped body. Quick-change heads and tool-free mandrel swaps make it suitable for on-site repairs, assembly lines and home projects where space, speed and organized storage matter.

How does this 3-in-1 tool switch between functions?

Switching modes requires changing the removable head or selecting the appropriate mandrel. The WE-890 features tool-free head changes and a sleeve-mounted rivet head, so conversions between rivet nut setting, pop riveting and reaming are fast and straightforward.

• Tool includes six mandrels: M5, M6, M8, 10-24, 1/4-20, 5/16-18 for metric and SAE threads.
• Five rivet heads cover common pop-rivet sizes from 3/32" to 1/4".
• One reamer for cleaning and enlarging holes between operations.
• Head or mandrel changes require no additional tools, speeding workflow.

What hardware is included and what materials will it work with?

The kit ships with 60 rivet nuts, 50 blind rivets, six threaded mandrels and five rivet heads, all arranged in a molded carry case for easy transport. It handles a wide range of light- to medium-duty fastening tasks across aluminum, thin steel and many sheet materials—note limitations with heavy stainless rivets for the largest head.

• 60 rivet nuts and 50 blind rivets to start jobs without immediate reordering.
• Mandrels for both metric and SAE thread standards, useful for mixed fleets or parts.
• Guidance: 6.4mm head is not recommended for steel or stainless rivets.
• Blow-molded case keeps components secure and labeled for quick access.

How does the tool feel and perform in use?

Ergonomic non-slip handles reduce hand fatigue during repeated pulls, and the solid build gives reliable leverage for most assembly tasks. The unit’s design focuses on efficient operation: mandrel and head swaps are fast and the included reamer helps prepare accurate holes for consistent fastening.

• Ergonomic, non-slip grip for extended use with less fatigue.
• Durable construction for workshop or field jobs.
• Quick-change head system minimizes downtime between tasks.
• Compact size fits toolboxes and service vans easily.

What are practical use cases and common industries for this kit?

The WE-890 is aimed at users who need versatile fastening solutions: from vehicle body work and aviation interiors to furniture assembly and light industrial manufacturing. It’s useful wherever blind riveting or blind nut installation is required in pipes, panels or thin structures.

• Automotive trim, body panels and aftermarket installs.
• Aerospace interiors, instrument panels and lightweight assemblies.
• Furniture, elevator components and metal fabrications.
• On-site maintenance and manufacturing line quick repairs.

Who is this for? If you want one lightweight, organized kit that covers pop rivets, rivet nuts and light reaming without carrying multiple separate tools, the WETOLS WE-890 will suit mobile technicians, hobbyists and small shop professionals. It’s especially useful when space is limited and rapid changeover between rivet types and thread standards is needed. For heavy structural stainless-steel rivets, consider a dedicated high-force tool; for everyday fastening and repairs, this set delivers broad capability in a portable package.
