Milwaukee 120 Volt Armature
Model Number: 16-70-0300
The Milwaukee 16-70-0300 is a genuine OEM 120 Volt Armature for Milwaukee 7 in. and 9 in. sanders and grinders. The armature is the central rotating component of the tool's motor: it is built from a steel shaft, copper windings, and a series of commutator bars, and as the carbon brushes ride against the commutator they transfer electrical current into the spinning windings, converting electrical power into the rotation that drives the tool. It is the heart of the motor, so its condition directly determines whether the tool runs with full power. This armature is rated for 120-volt tools, the standard US line voltage, so it is matched to the motor of a 120V tool and is distinct from an export-voltage version. The armature is a component that fails under hard use: if the tool is repeatedly overloaded, the copper windings can overheat until the insulation melts and the armature shorts or fails, and worn commutator bars or a damaged shaft degrade performance. When the armature fails, the tool loses power, runs rough, sparks excessively at the brushes, or stops running entirely. Replacing it with the correct genuine Milwaukee OEM armature restores the motor's rotation and full power output.
Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your tool's serial number against the official Milwaukee service parts diagram before ordering to confirm this is the correct armature for your tool. This 120 volt armature is used across a range of Milwaukee 7 in. and 9 in. sanders and grinders, including models such as the 6065, 6066, 6095, and 6096 sanders and the 6067, 6068, 6070, and 6098 grinders, so confirm your tool's catalog and serial number against the parts diagram before ordering. It is strongly recommended to replace both carbon brushes at the same time as the armature, since worn brushes will quickly wear a new armature's commutator, and to inspect the field, bearings, and commutator when servicing. Handle the armature carefully during installation, especially any cooling fan, and reuse the bearings only if they are undamaged. Because this is a motor repair, follow the correct service procedure and re-grease the gear mesh with the Milwaukee-specified grease where the diagram calls for it. The field, carbon brushes, brush holders, bearings, and gearcase components that work with the armature are separate parts, so refer to your tool's parts diagram for the correct companion part numbers.
