## Description

With a straight-body design and a 1/4-inch collet, the AOBEN AT3504X is built for focused grinding work where access and control matter. Its corded motor reaches up to 28,000 RPM, and the standard collet accepts compatible grinding accessories and rotary bits for tasks such as metal grinding, deburring, carving, polishing, and shaping.

A paddle switch adds a practical safety feature by helping prevent accidental startups. Compared with a setup intended for broad surface work, a straight die grinder is suited to localized jobs and tighter areas, including automotive work, fabrication, and general metalworking.

## Tech specs
- Type: Corded straight die grinder
- Model: AT3504X
- Motor: Pure copper
- Maximum speed: 28,000 RPM
- Collet: 1/4 inch
- Switch: Paddle switch

The motor’s stated speed and the compatible collet make this tool useful for detailed work with appropriate rotary accessories. Choose a bit suited to the material and task, then secure it in the collet before use. The paddle switch provides a straightforward control point while working through grinding, polishing, or finishing steps.

## Compatibility & requirements
The 1/4-inch collet is designed for compatible grinding accessories and rotary bits. Matching the accessory shank to the collet lets you use the grinder for different kinds of metalworking, from removing burrs to shaping or polishing a workpiece. The tool is corded, making it a fit for workshop tasks where a corded grinder suits the work area and setup.

The straight-body format helps reach tight areas that can be awkward to approach with broader grinding tools. For example, during automotive repair or fabrication, it can be used for localized grinding or deburring around a workpiece, while a tool designed for larger surfaces may be more appropriate for wide, open areas. Select an accessory for the material and operation, and keep the workpiece secure during use.

## Everyday use
Use the grinder for metal grinding, deburring, carving, shaping, and polishing, as well as welding repair and workshop projects. Its range of compatible rotary accessories supports different finishing tasks with one tool, while the paddle switch makes starting and stopping part of the normal hand position. For a repair job, it can help address a specific rough edge or work on a confined section without treating the whole surface as the target.

The product is also suited to fabrication work where several operations may be needed on a part. Moving from shaping to deburring or finishing can be done by selecting the appropriate compatible bit for each task. The straight design is especially useful when the work calls for access into tighter spaces, for larger, flatter areas, a tool matched to broad-surface grinding may better suit the job.

## When it makes sense
The AOBEN AT3504X makes sense for workshop users who need a corded grinder for focused metalworking and finishing, with a 1/4-inch collet for compatible bits and a straight body for reaching tight spots. Its 28,000 RPM maximum speed, copper motor, and paddle switch address the core needs of grinding, deburring, shaping, and polishing. If those are the jobs on your bench, this die grinder offers a practical format for handling them with the right accessory in place.
