FLEX 24V 3-Inch Mini Grinder Kit: Big Cutting Power for Tight Spaces

A full-size grinder is great until the cut is behind a pipe, against a wall or wedged somewhere your hands barely fit. At that point, more tool is not necessarily better. It is just more tool to wrestle with.

The FLEX 24V 3-Inch Mini Grinder/Cut-Off Tool Kit is made for those jobs. It delivers up to 20,000 RPM in a compact design that can cut, grind and surface material without taking over the entire workspace.

Tradespeople get a maneuverable option for quick cuts in cramped areas. DIYers get a complete starter kit that does not require a separate battery, charger or immediate run to the store for accessories.

The biggest advantage is not simply its size. It is how easily the tool can be positioned around the work.

1. Rotatable head: Adjust the tool for better grinding ergonomics and right- or left-handed cutting.
2. Reversible blade rotation: Control the cutting direction based on the material, angle and approach.
3. Up to 20,000 RPM: Provides the speed needed for cutting and surfacing applications involving pipe, rebar, threaded rod and sheet stock.
4. Touch-controlled variable speed: Adjust the tool’s speed to suit cutting or grinding applications.
5. Electronic brake: Stops the wheel quickly to help keep work moving between cuts.

That combination matters when the job is not happening conveniently in the middle of a workbench. Sometimes the cut is under a sink, behind installed equipment or inside a partially finished project. The FLEX mini grinder is designed for exactly that kind of inconvenience.

For Tradespeople

Metalworkers and maintenance crews can use it for cutting sheet stock, trimming threaded rod and handling small surfacing jobs. Contractors can reach rebar and metal components in areas where a larger grinder would be difficult to position.

The included diamond tile wheel also gives remodelers and tile professionals another option for controlled tile cutting. With the correct wheel installed, one compact tool can move between several common jobsite materials.

For DIYers

Home projects have their share of stubborn metal. A rusted bolt refuses to move. Threaded rod needs to be shortened. A piece of sheet metal does not quite fit. A tile needs one last cut before it can go into place.

This kit provides the tool and accessories needed to handle those smaller cutting and grinding jobs without stepping up to a bulky full-size setup.

“Kit” can be a generous word in the tool industry. Sometimes it means the tool and a bag with plenty of room for everything you still need to purchase.

This package is considerably more complete. It includes:

1. FLEX 24V 3-inch mini grinder/cut-off tool
2. 2.0Ah Stacked Lithium battery
3. 160W Fast Charger
4. Three-inch cut-off disc
5. Three-inch grinding disc
6. Three-inch multi-material cut-off wheel
7. Three-inch diamond tile wheel
8. Clip-on cutting guard
9. Dust-extraction hose connector
10. Allen wrench
11. Belt clip
12. FLEX carrying bag

The included battery and charger make this especially attractive for someone entering the FLEX 24V system. Existing FLEX users also gain another battery and charger that work across compatible FLEX 24V tools.
