Each bit uses a standard 1\/4\" hex shank to fit most corded and cordless drills, letting technicians and DIYers perform tube butt expansion or 45° flares quickly on site. Forged from high-density carbon steel with a rust-resistant finish, the bits are machined for repeatable shapes and long wear life.\u003c\/p\u003e\n\n\u003ch3\u003eWhat sizes are included and which tubing do they work with?\u003c\/h3\u003e\n\u003cp\u003eThe set includes six swaging bits sized 1\/4\", 3\/8\", 1\/2\", 5\/8\", 3\/4\" and 7\/8\", plus five flaring bits in 1\/4\", 3\/8\", 1\/2\", 5\/8\" and 3\/4\".

Work steadily at moderate speed and avoid excessive pressure; the bit shapes tubing by controlled rotation rather than force alone.
