About [8-Size_2 Sets] Bore Brush Set, Brass / Copper Wire

Description This bore brush bundle includes 2 sets of 8-size cleaning brushes (1(1/8), 1.0, 7/8, 3/4, 5/8, 1/2, 3/8, and 1/4-inch). The brush bristles are made with brass wires for effective cleaning. The 1/4-inch shank on the brush fits most power drills. The brass bristles are softer than stainless steel ones, and remove dirt, rust, corrosion, etc. but are gentle not to damage harder metal surfaces. They are commonly used in applications that include, but are not limited to: (1) firearm maintenance and gun cleaning to clean the inside of barrels or bores, (2) cleaning the inside of pipes and tubes such as plumbing, HVAC, and automotive pipes, tubes, and fittings, (3) cleaning grills to remove grease and grime, (4) cleaning cylinders or bores of engine parts, exhaust systems, boat props, and other automotive and mechanical components, (5) removing rust, corrosion, scale, deposits, or oxidized layers, (6) surface preparation for applying coatings, and other various applications. 1. Please ensure necessary precautions and wear appropriate PPE. 2. Prepare the cleaning area by protecting or removing the parts not to be cleaned. 3. Select the appropriate size of bore brush for the task at hand. Using the wrong size may damage the tools and/or parts. 4. Use the bore brush only on a power drill, not an impact driver. Impact driver may cause damage to the tools or parts. 5. Set the drill to run at a low speed to avoid high torques. Low speed is sufficient to effectively clean the parts or surfaces. 6. Make sure the drill is set to run in the clockwise direction. The brushes are not designed to run counterclockwise. 7. When cleaning the inside of pipes, fittings, barrels, tubes, etc., align the brush to their axes. 8. Avoid applying too much unsymmetrical lateral force to the brush. 9. Keep the drill running while inserting the brush and removing it. Do not reverse the rotation direction of the drill at any point during the cleaning process.
