Innovative Products of America (8080) 6 Piece Twisted Wire Stainless Steel Bore Brush Set for Cleaning Tubes, Ports, Bearings and More

The job was way tougher than I thought. I should have ordered something a little more heavy duty.

Good quality

works as expected

I use these to.clean my water bottle straws. I have had them 2 years now and no issues at all.

The end of the shaft is just shoved in there It pulls apart don't recommend bad quality

I picked these up for cleaning out bolt holes as well as automotive brake caliper slide pin bores. Always a struggle to clean junk out of those, usually blind pin holes to get the caliper sliding easily again. these fit the bill. Chuck them up in your drill and go to town. There is a size that has fit all the things I have tried using them on so far. They have so far been quite durable. No complaints.

These are OK. They have a little more spring and less durability than I had hoped they would given the higher price point as some others, but these do hold up way better than the cheaper options that hardly last a couple of minutes in a low speed cordless drill. They do a good job reaching into tight places and the set has a good range of sizes. Best for light duty applications.

I believe this product deserves better ratings. I was wary before purchase but I am after using them, happy with my purchase. I didnt experience brittle tines like others did. If you use the product correctly, it will work fine. Use the tips of the tines to clean, and just use light pressure to allow the ends of the tines to scrape against your surface (in my case, the inner threads on car parts). Make sure your attachment can fit inside the areas you are going to use it without bending any of the tines before you use it. If you allow the tines to twist, or put so much pressure tht the attachment breaks, that's your fault. 5/5 would buy again
