Brush Research BC20024 FLEX-HONE®, 2" (50.8mm) Diameter, 240 Grit, Silicon Carbide, For Mild Steel, Stainless Steel, Cast Iron and Softer Ferrous Materials

I used this to deglaze a cylinder for my Stihl 661C.Oiled the hone with 30 weight oil and ran in forward and reverse in and out 3 times in each direction on the low setting of a cordless drill. Make sure it's spinning before you push it into the cylinder and pull it all the way out before you stop. Check it, then go maybe 5 more times max. Honing was the last step in the cleaning process.

Don’t count on it to be delivered on time, Amazon screwed the pooch again, about time to drop Prime, every delivery is after their “scheduled” delivery date

It works well

Use to hone a dirtbike cylinder an worked perfect

I purchased the 1-1/8" (28.6mm) hone, but the hone outside diameter actually measures 1-1/4" (31.75mm). Am I missing something?

Worked perfectly for dodge 4.7 lifter bores, one lifter was stuck due to damage to the lifter boss caused by the rocker arm falling out of place. After getting creative and getting it out, this hone had a new one easily gliding in and out within 10 seconds of medium speed drilling.

this is a number one company , worked as it should very happy

Worked as advertised fixed a backpack blower cylinder that was cooked just put 10w30 on it and read the instructions easy diy fix
