WETOLS 3-in-1 Rivet Gun Kit — 5 Rivet Heads, Mandrels & Reamer in Carry Case, Portable Multi-Function

The WETOLS 3-in-1 Rivet Gun Kit combines a rivet nut tool, hand riveter and reamer in one portable case so you can set rivet nuts, pull blind rivets and deburr holes with a single tool.

This all-in-one kit is built for workshop versatility: swap heads to convert between a mandrel-driven rivet nut setter, a conventional rivet gun and a reamer for finishing holes. The kit ships with six mandrels, five rivet heads, 60 rivet nuts, 50 rivets and a blow-molded carrying case that keeps every piece organized and ready on the job.

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

Head changes are tool-free and rely on quick-release fittings, letting you convert functions in seconds. The handle design positions four rivet heads on the tool and one in the sleeve for immediate access.

• Rotate or pull the sleeve to release and fit a new head.
• Mandrels screw into the tool for rivet nut installations.
• Reamer fits into the same quick-change interface for deburring and hole cleanup.

What comes in the kit and how is it organized?

The set includes every basic component needed for most light- to medium-duty fastening jobs, all stored in a custom blow-molded case so parts don’t shift in transit. Contents are labeled and slotted for fast inventory checks.

• 3-in-1 rivet nut tool (main unit) and user manual.
• Mandrels: M5, M6, M8, 10-24, 1/4-20, 5/16-18 for rivet nut sizes.
• Rivet heads: 2.4mm, 3.2mm, 4.0mm, 4.8mm, 6.4mm; plus 60 rivet nuts and 50 rivets.

Which materials and rivet sizes are supported?

The tool handles a range of blind rivet diameters and rivet nut threads suitable for aluminum, mild steel and many fabrication tasks. Note the 6.4mm head is not recommended for steel or stainless rivets — choose smaller heads or compatible materials accordingly.

• Supported rivet head diameters: 3/32" (2.4mm) to 1/4" (6.4mm).
• Mandrel thread sizes cover common rivet nut standards up to 5/16-18.
• Use aluminum or softer metals with the largest head for best results.

The ergonomically shaped, non-slip handles reduce hand fatigue while the quick-change design removes the need for extra tools when swapping mandrels or rivet heads. Metalworking and maintenance pros will appreciate the compact transport case that protects components and keeps consumables organized.

Who is this for? This kit is aimed at DIYers, maintenance technicians, small fabrication shops and automotive or furniture assemblers who need one compact tool to handle threaded rivet nuts, blind rivets and hole finishing. It’s most useful where space, portability and fast setup matter — garage projects, installation jobs and on-site repairs.
