Background and Identification

Handheld angle grinders in general were invented first in 1954. Since then, every tool company has put their own spin on the design. This particular device can be identified by the bold RIDGID logo and brand colors of orange, black, and grey. The product itself is named by RIDGID R1020 with the last digit representing where you bought it. This one specifically is the R10202.

A 15 amp motor powers this grinder featuring a 7-inch grinding disk allowing for a maximum speed of 8,200 rpm without an applied load. Sealed bearings, a three-position side handle, and a rotating main handle are also features of this device. The device additionally features a spindle lock for easy accessory changes. In whole, the device weighs approximately 8 pounds.

The device consists of 6 main parts: the casing, motor, twist handle, side handle, output shaft assembly and grinder disk. The casing is molded to fit the motor while the handle is attached to the casing by six Torx T20 screws. The motor is held inside the casing by four M5 X 28mm Torx screws located on the front of the device. The grinder disk is located on the frontmost part of the output shaft assembly and is held on by a clamp nut and threaded shaft. The carbon brushes are located on either side of the motor casing.
