Brush Research FLEX-HONE Cylinder Hone, GB Series, Silicon Carbide Abrasive, 4-1/8 (105 mm) Diameter, 240 Grit Size

Its worked great for dressing up the cylinders on the v6 i was working at school. It provided a great crosshatch pattern for the rings to sit to. FYI. Make sure to use a very light weight oil during the honing process.

Excellent product. Brush hones are a very good thing to have around and BRM makes about the best ones. The price on amazon is inline with just about everywhere else so cant complain there. I used this particular hone on a standard bore small block ford engine block to hone the cylinders before I installed the pistons and rings. The 180 grit has worked great for me with standard Iron piston rings. If youre using moly rings or something else, refer to the manufacturers recommendation when choosing grit size. I also like the brush hones because you can purchase one for less than a machine shop will charge you to hone your cylinders, and you can usually do more than one block with one. The last BRM hone I had did 5 small blocks and still has some life in it. Take that for what you will. Very good product at a very good price. Definitely recommend for your rebuild or re-ring project!

worked perfect to deglazed cylinder wall on 2003 Ford Focus 2.0L SPI , also known as the dropped valve seat engine SOHC. Adds a nice crosshatch to cylinder. Directions for use were on end of brush box.

Great price, really a great price, compared to auto parts store in my area.

Does an excellent job honing cylinder walls. Makes it easy to get a perfect cross thatched finish. For this price it is a very good tool.

This is the only hone to use on engine cylinders. I am a master mechanic and the reasons are many. The cross hatch pattern this hone makes is the best for breaking the glaze on new rings and seating them in. Brake type hones are good for rubber seals, plungers, etc to steel bores but not for high friction steel to steel applications. Dont be a cheap skate when it comes to your engine - Go with the best parts and practices. Also, dont use Synthetic oil in engines with new rings. Get at least 500 miles on them and then switch to a synthetic (Same Brand) if you want to use it.

Great cylinder hone for rebuilding engines, produce great cross hatching and a nice hone job.

Used to hone cylinder bores on engine rebuild. Nice cross-hatch finish.

I have a 3000 mile freshly rebuild 355 sbc. Went with new rings rods and pistons.. A quick Hone to knock the glaze off was exactly what it needed. Does a great job !!

Couldnt find in stores, these are great for mild rebuilds. Cleaned up cylinders in just a few passes. Use care cleaning up as grit and tool material gets everywhere.
