This tool set includes 4 cleaning brushes: 1 pipe cleaner and 3 fitting cleaners.
The 1/2-inch copper pipe cleaner, Kwalitistar's model InerLok050, features a newly-engineered internal locking mechanism that anchors the brush housing and drive shank tightly. This update improves the durability of plastic housing and reduces the likelihood of shank spinning relative to housing. The InerLok050 copper pipe cleaner is designed to clean the outside of copper pipes / tubes with a diameter of 1/2-inch (nominal size 1/2”, measured OD around 5/8”).
Those three 1/2-inch fitting brushes are used to clean the inside of copper, brass, and bronze fittings. The diameter of these 3 brushes is slightly bigger than that of fittings for effective cleaning.
They prepare 1/2-inch pipes and fittings for subsequent fluxing, soldering, sweating, brazing, or welding. The 1/4-inch shank on the brush fits most power drills. Brush bristles are made with stainless-steel wires for effective cleaning. It is a tool set for homeowners, DIYers, plumbers, and contractors, etc.
Instructions:
1. Safety first: please ensure necessary precautions & wear appropriate PPE that includes, but is not limited to, safety goggles, protective gloves, face masks, etc.
2. Use these cleaning brushes only on a power drill, not an impact driver. Impact driver may cause damage to the tool or parts.
3. Set the drill to run at a low speed to avoid high torques. Low speed is sufficient to effectively clean pipes / tubes.
4. Make sure the drill is set to run in the clockwise direction. The brushes are not designed to run counterclockwise.
5. Align the axis of the brush to pipes / tubes / fittings while using the tool.
6. Keep the drill running while inserting the pipes / fittings and removing them from the brush. Do not reverse the direction of the drill at any point during the process.
