Circular saw plunge pipe cutter

A circular saw plunge pipe cutter comprising:

• a main housing including a guide plate having at least one guide collar;
• a shoe slidably coupled to the main housing in which a pipe is receivable, the shoe includes at least one guide pin that fits into the at least one guide collar to allow the main housing and shoe to slide relative to each other;
• a saw blade movable relative to the shoe;
• and
• a drive mechanism at least partially disposed within the main housing for driving the saw blade, wherein the drive mechanism includes:
• an electric motor;
• a bevel pinion driven by the electric motor;
• a compound gear including a bevel gear portion engaged with the bevel pinion and a spur gear portion coupled for co-rotation with the bevel gear portion;
• an arbor shaft to which the saw blade is mounted, the arbor shaft including an arbor gear;
• and
• an idler gear engaged with both the spur gear portion and the arbor gear to transfer torque from the compound gear to the arbor shaft;
• and
• wherein the electric motor defines a motor axis that is parallel with a plane of the saw blade, and wherein the arbor shaft defines an arbor axis that is perpendicular to the motor axis, and
• wherein a gear ratio between the idler gear and the spur gear portion is at least 5:1.

A circular saw plunge pipe cutter comprising:

• a main housing;
• a drive mechanism at least partially disposed within the main housing;
• a saw blade operably coupled with the drive mechanism;
• and
• a shoe slidably coupled to the main housing, wherein the shoe includes a shoe housing that fits around an upper portion of the main housing, and
• wherein the shoe includes a first portion that is fixed relative to the shoe housing and a second portion that is movable relative to the shoe housing between a first state, in which the second portion is aligned with the first portion, and a second state, in which the second portion is misaligned with the first portion.
