Wide Range of Uses Home Air Conditioner Repair Home Refrigerator Repair Refrigeration Equipment Manufacturing Refrigeration Equipment Repair The 5PC flaring drill bits are an innovative toolset, which provides a high-temperature, leakage-free flaring method, designed for the most common tubing diameters in HVAC systems. The high-temperature method preserves the copper's/aluminum's malleability while performing the flare, preventing cracks and leaks. The tools were developed and are recommended for soft copper. The drill bit set makes flares with the ideal dimensions for a perfect packing, due to a wider area of contact between the flare surface and the valve/tube accessory. To top that, you can make flares with the bits in just 5 seconds! To perform the flaring in copper/aluminum tubing, simply attach the corresponding tool size to a drill. Because they perform their job using high temperature and friction, no clamping tools or holders are necessary. In addition, the bits are equipped with a 1/4 inch hex shank, which allows quick release and will largely improve your work efficiency.
