Kapro Tools 257 Flex Sander

Kapro Flex Sander Works Corners, Grooves, and Curves with Ease

Hand sanding can be a chore, particularly when you run up on corners, edges, and curves. But, Kapro Tools has introduced an innovative adjustable hand sanding tool to make that chore less taxing. The Kapro 257 Flex Sander can handle corners, narrow spaces, and even concave and convex curves with ease. This tool differs greatly from the Kapro 905DG digital level, but it’s every bit as much an innovative tool.

What Is Kapro Saying About the 257 Flex Sander?

Although we designed the 257 Flex Sander to help tradesmen with nonstandard sanding tasks, its convenient, ergonomic design makes it a go-to for everyone from pro to weekend warrior.

What’s the Big Deal?

The Kapro Flex Sander has a 6″ base and works with a standard piece of 6″ sandpaper with Velcro backing. It features a solid center for stability and wings that can fold up or down independently of one another to accommodate all the angles of your workpiece. It gets into tight spots, corners, narrow spaces, grooves, and works on flat or curved surfaces.

Kapro designed this flexible hand sander with a removable ergonomic grip handle for extra control and precise pressure. The 6″ diameter base of the Kapro Flex sander is backed with hook and loop material, so when it’s time to change to a fresh piece of sandpaper, you only need to rip the old piece off and press the new piece on to keep it securely in place.
