WETOLS 3-in-1 Rivet Gun Kit — Rivet Nut Tool, Blind Riveter & Reamer with 5 Heads, Case

The WETOLS 3 in 1 Rivet Gun is a compact multi-function hand tool that switches between rivet nut setting, blind riveting, and reaming to handle fasteners across metal, plastic, and composites.

This all-in-one kit consolidates three common shop functions into a single ergonomic tool, plus a selection of mandrels, rivet heads, rivet nuts and a blow-molded case for organized storage. It’s built to speed small repair and assembly jobs where carrying multiple tools would be inefficient. The kit includes everything needed for many routine fastening tasks: six mandrels sized for common threads, five blind-rivet heads, fifty rivets, sixty rivet nuts and a reamer for cleaning holes.

How do I switch between rivet nut tool, rivet gun and reamer modes?

Changing modes is tool-free and quick: swap the head or mandrel to the matching sleeve and you’re ready to operate. The kit ships with several pre-installed heads to reduce setup time and the sleeve holds one additional head for convenience.

• Rotate and pull to release the active head, then insert the desired mandrel or rivet head.
• Four rivet heads are stored on the handle; one head sits in the sleeve for fast access.
• Use the included reamer in the same handle to deburr or widen holes before fastening.

What sizes and fasteners are included, and what materials can they be used on?

The kit supplies a broad assortment to cover many small assembly and repair jobs: M5–5/16-18 mandrels, five blind-rivet head sizes, fifty rivets and sixty rivet nuts. These components fit aluminum, soft steel, plastic and thin sheet-metal applications; but take care with the largest rivet head on very hard steel or stainless where it’s not recommended.

• Mandrels: M5, M6, M8, 10-24, 1/4-20, 5/16-18 for common nut-rivet sizes.
• Rivet heads: 2.4mm (3/32"), 3.2mm (1/8"), 4.0mm (5/32"), 4.8mm (3/16"), 6.4mm (1/4").
• Rivets and rivet nuts included for immediate use; avoid 6.4mm head on hardened steel rivets.

How comfortable and durable is the tool for repeated use?

The handle is built with a non-slip grip and ergonomic contours to reduce hand fatigue during repetitive pulls. Quick-change components minimize downtime, and the supplied blow-molded case secures parts and protects threads from damage in transit or storage.

• Ergonomic non-slip handle for better control and reduced hand strain.
• Quick-change head and mandrel system eliminates extra hand tools.
• Blow-molded case keeps mandrels, rivets and accessories organized and protected.

Who this is for: the WETOLS 3 in 1 rivet gun kit is aimed at DIY enthusiasts, maintenance technicians, small fabrication shops and automotive hobbyists who need a portable, versatile fastening solution without buying separate specialty tools. It’s especially useful for light-to-medium fastening tasks on sheet metal, cabinets, signage, frames and simple vehicle bodywork where speed and convenience matter. If you frequently swap between blind riveting, setting rivet nuts and prepping holes, this kit reduces toolbox clutter while providing a ready set of sizes for common jobs.
