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

I bought this hone to deglaze cylinders on an old engine for new rings. It worked as advertised. So long as you don’t have a ring ridge you will be able to use this product.

Works very well - easy to use if careful.

This seems to be a well made tool. The abrasive tip is connected to the metal center with plastic leaders but they seem to be sturdy enough to handle the work. If you are reading this you know what it is for and it seems to fit the bill quite well. Keep in mind when purchasing that you will want to make sure you get the size and grit needed for your application.

Recieved way sooner than expected. Very happy. Thank you!

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

it works

Great product and works great

I used this hone on a 2.4l Volvo block to deglaze and put new cross hatching in the cylinders. This hone works amazing and was worth every penny. I was very nervous about doing this myself but after the first one I was comfortable with it. I used a Dewalt 20v drill on high and ran it up and down multile times for 2 passes using ATF as lubricant. The before and after speaks for itself. This thing works great.

Best hone by far

Stock engine refresh 4.0in bore. This thing worked great. Tip: Get a buddy and make them keep it flooded with lube while you stroke it;) Use wd40 or whatever is cheap. Youll use most of a can. Then wash that engine with soapy water and a brush, or just pressure wash it. Its going have lots of fine metal particles everywhere from the hone process.
