Abrasive grit is formed into spheres and suspended a the end of individual nylon filaments. Designed for conditioning a cylindrical I.D. surface, it is self-aligning and self-compensating for wear. The tool imparts a surface that is optically smooth and metallurgically free of any fragmented or scored metal from boring operations.

Flex-Hone® Tool:
Instructions for use:
- The Flex-Hone Tool should be rotating upon entry and removal from cylinder.
- RPM from 1200 to 60 depending on diameter.
- Stroke from 30 to 200 per minute depending upon RPM.
- Average 350-500 RPM at 60-120 strokes. Final stroking may be accelerated to develop 45° cross hatch.
- OEM high production needs experimentation with different mineral or water-soluble honing oils for optimum results. For convenience, use a 10W30 motor oil or Flex-Hone Oil. Wash cylinders, preferable with water, br/ush and detergent. Then dry and oil.
- Experiment honing time from 10 to 45 seconds to see what is sufficient to develop plateaued finish free from cut, torn and folded metal.
- Do not over-hone.
