10-Piece Tube Cleaning Brush Kit | Brass Wire Bore Brushes & Stainless Steel Brushes 12" Long (1/4" to 3/4") for Tubes, Cylinders, and Narrow Spaces

I cut off some of the handles so I can use them in an electric drill or flexible drill holder to clean internal threads. speeds up a job. Good for follow-up when using a thread chaser on spark plugs. I am told one should not use anti-seize compound on spark plug THREADS . On FORD 5.4 V8 triton you do use Nickel Anti seize but on the long Unthreaded part that extends deep into the cylinder head as this part is what attracts carbon and often breaks off requiring the FORD techs to charge you $150 for each broken spark plug that has to be removed with one of the kits sold for this terrible FORD engine. FORD charges $400 to change eight spark plugs on the 5.4L V-8 PLUS $150 for each spark plug that breaks in the removal process. And I can guarantee you that nobody has zero spark plugs removed intact on this FORD engine. After you have this experience you either trade for a Dodge or Chevrolet or Tundra or opt for a FORD without an engine that takes the extended reach spark plugs unless you have set aside $800-$900 for a spark plug change.

I bought these to use around the parts washer to clean out bolt holes and such. They seem sturdy and the bristles are tight and even. About the first thing I did was try to run a stainless brush through a 5/16 hole a couple inches deep through an aluminium bracket which had heavy corrosion. Of course it was a touch too tight and got stuck, then as with any bore brush, it wouldn't back out. After putting the bracket in the vise and working the brush through with vise grips and significant force, it was no worse for wear. I think they'll hold up well to normal abuse.

These are basically gun barrel cleaners. I wanted something smaller and with denser bristles.

I love this product. There's several different sizes and the work great for cleaning out the siphon tube in a toilet. I wish I had bought this last year, it have saved me a lot of money trying everything under the sun to clean out the siphon tube.

I have started to make jewelry and realized that I needed some tubular brushes when cleaning pieces and these are working great for my needs. I probably didn’t need the larger brushes for my jewelry, but they have come in handy for jobs around the house. Came well packaged and on time. Would buy from this seller again.

A little expensive for the sizes included and quality of product. But useful and not a waste.

Work great to help me clean the stringing in my 3D prints.

Good quality
