Features / Benefits
- SURFACE FINISHING - The Flex-Hone Tool is available in a variety of abrasive types and grit selections to provide the optimum surface finish on any base material
- The Flex-Hone is commonly used to reduce Ra, Rk and Rpk values while maintaining Rvk and Vo volume for oil retention
- Using the Flex-Hone Tool for surface finishing allows the sizing tools to do their jobs quickly and accurately without fighting surface finish
- The Flex-Hone is also used in adhesive bonding applications where a rougher surface is desired for bonding integrity
- DEBURRING - Debarring of cross drilled holes is an expensive, time consuming operation. The Flex-Hone Tool can be used to remove burrs from cross drilled holes leaving a clean, radiused intersection
- Because of its unique construction, the Flex-Hone can be used online in machine tool applications or offline as a secondary operation
- The tool is self-cantering and self-aligning to the bore so elaborate, rigid set-ups are not required
- It is advisable to use the tool in the main bore into which the cross holes break
- Best results are obtained by rotating and stroking the tool a few strokes in a clockwise direction, removing the tool from the part, reversing the spindle and then rotating and stroking the tool in a counter clockwise direction for a few more strokes
- This forward and reverse rotation creates a more symmetrical debarring pattern
- PLATEAU FINISHING - Brush Research pioneered the concept of a plateau finish and is a strong proponent of the benefits of a cross hatch, plateaued finish
- The concept involves removing the peaks produced by prior machining operations and creating a substantially flat or plateau finish
- A plateau finish created by the elimination of peaks allows rings and seals to seat without damaging their edges
- The cross hatch pattern will aid in lubrication control and retention, reduce seepage in hydraulic and pneumatic applications and promote longer seal life

This thing is bad ass... if you just need a quick clean up. If you've got gouges in the bore this isn't gonna fix it, but if you need a deglaze this is your tool. I used this on a 4.8 LS engine worked like a charm.

I'm really impressed with how well this cleaned up my 94mm VW cylinders. With WD40 and maybe 60 seconds of back and forth it cleaned the glaze off the cylinders and left a nice cross hatch pattern. Super easy and in my humble opinion, way easier than the old 3-stone hones. The downside is you may need multiple hones for different bores but for me it worked out really well.
