Pipe threader

A pipe threader configured to rotate a die head with cutting dies, the pipe threader comprising:

• a housing;
• an electric motor supported in the housing;
• a battery coupled to the housing to power the electric motor;
• a die holder that receives torque from the electric motor causing the die holder to rotate, the die holder defining a rotational axis;
• and
• a die locking mechanism configured to rotationally lock the die head received within the die holder, the die locking mechanism including
• a first lock ring on a first side of the die holder, and
• a second lock ring coupled to the first lock ring on a second side of the die holder opposite the first side,
• wherein the first lock ring and the second lock ring are each configured to rotate about the rotational axis with respect to the die holder to engage an outer surface of the die head to selectively mount the die head in the die holder, and
• wherein the first lock ring defines a first octagonal pattern opening, the second lock ring defines a second octagonal pattern opening, the die head defines an internal octagonal surface portion, each of the first lock ring and the second lock ring is rotatable between an alignment position and a misalignment position, in respective misaligned positions, the first and second pattern openings are misaligned with the internal octagonal surface.
