FAQ

HOW EASY IS THE FLEX-HONE® TO USE?

It is very easy to use. The abrasive globules each have independent suspension that assures the Flex-Hone to be self-centering, self-aligning to the bore and self-compensating for wear. No time-consuming training or set up is needed .

WHAT IS THE DIFFERENCE BETWEEN A FLEX-HONE® AND BALL HONE®?

There is no difference. The Flex-Hone® and Ball Hone® are both trademarked names for our tools. We market the tool under the name Flex-Hone, but a common name is Ball Hone. Colloquially, some people also refer to the tool as a dingleberry hone, grape hone, bead hone, bottle brush hone, glaze buster/breaker hone, or flexible hone, but we do our best to dissuade the usage of those terms and to promote Flex-Hone. In any case, if it says BRM, you've got the best.

WHAT RPM DO I SPIN IT AT?

The RPM will vary with the size of the tool and will range from 1200 to 60 RPM. The smaller the hone, the faster the speed. For a 1" tool, for instance you will want to be at around 800 RPM, for a 3" tool, you should be near 700 RPM, for a 6" tool, you'll be nearer to 450 RPM and so on. These are just guidelines and optimal performance for each specific application will be found with a bit of experimentation and testing. The Flex-Hone tool is a low RPM tool. Specific RPM is dependent on the diameter of the tool and the application. General speed ranges are given but, again, machine trials are required to verify the parameters. For more details, check out the FAQ page.

HOW DO I KNOW WHAT GRIT AND ABRASIVE TYPE TO USE?

The grit and abrasive type is identified by two key markings, one on the stem and one on the tip. The stem markings identify the abrasive type and the tip markings identify the abrasive grit. Please see the Abrasive/Grit chart for details.

WILL IT REMOVE TOO MUCH MATERIAL?

No. The Flex-Hone tool is a surface finishing tool, not a material removal tool. We are reducing the rough peaks of a surfaces microstructure and typically we only remove a small amount of material.
