## Description

The three-in-one format combines a rivet gun, rivet nut tool, and reamer in one hand tool. Switching the head changes the working mode, so you can handle different fastening tasks with a single kit.

Six mandrels cover M5, M6, M8, 10-24, 1/4-20, and 5/16-18 rivet nuts. Five rivet heads support rivets in several listed sizes, from 3/32" to 1/4".

A non-slip handle and ergonomic design support a secure, comfortable grip. The kit also comes with a blow-molded case that keeps the accessories in fixed positions for storage and carrying.

## Usage tips
Choose the rivet head or mandrel that matches the fastener, then change the tool head to select the required function. The head and mandrel can be changed without tools, making it straightforward to move between riveting and rivet-nut installation tasks. Keep the parts organized in their assigned case positions between jobs.

For a project involving metal panels or tubing, the kit lets you switch from setting rivets to installing rivet nuts with the same tool. Its listed applications include automotive, furniture, aviation, switches, elevators, instruments, and other metal manufacturing work. The assortment of mandrel sizes supports both metric and SAE rivet nuts, while the rivet heads accommodate several listed rivet diameters. For steel or stainless-steel rivets, the 6.4 mm rivet head is not recommended.

Compared with assembling separate single-purpose tools for these operations, this kit brings three functions and their related accessories together in one case. That setup is useful for repair and fabrication work where different fastening methods may be needed across a project. Match the installed head or mandrel to the fastener before use, and consult the included user manual for operating guidance.

## Box contents
The kit includes one 3-in-1 rivet nut tool, six mandrels, 60 rivet nuts, five rivet heads, 50 rivets, one reamer, one user manual, and one blow-molded case. The rivet heads are fitted in designated positions: four are installed on the handle and one on the rivet gun sleeve. The case keeps the accessories together and arranged for easier transport and storage.

## Final verdict
The WETOLS WE-890 suits hands-on fastening and fabrication tasks that call for rivets, rivet nuts, or reaming. Its combination of three functions, metric and SAE mandrels, multiple rivet head sizes, and organized carrying case makes it a practical kit for working across different metal assemblies without switching between separate tools.
