Abstract
In at least one illustrative embodiment, a grinding tool may comprise a housing including a mount, a shaft extending from the mount along a drive axis, where the shaft is configured to support a grinding wheel for rotation about the drive axis, and a guard coupled to the mount. The guard may comprise a central ring extending around the mount, a shroud extending radially outward from the central ring along a first portion of a circumference of the central ring, and a standoff coupled to a second portion of the circumference of the central ring. The standoff may extend from the central ring along a direction substantially parallel to the drive axis such that the standoff limits rotation of the guard about a tipping axis that is substantially perpendicular to the drive axis.
