A removable guard for a hand-held power tool. The guard is configured to cover an area proximate a spindle assembly of the tool between the spindle assembly and a user of the tool. The guard is further configured to be securely mounted to a semi-elastic lower bearing housing supporting the spindle assembly of the tool. The guard, when mounted to the semi-elastic lower bearing housing of the tool, and when in use during operation of the tool, must remain functional under conditions of flying debris, such as under conditions of an exploding, rotating abrasive grinding wheel mounted on the spindle assembly of the tool.The guard includes a clamp ring depending from a guard hood. The clamp ring's inner circumferential portion has at least a partially-knurled surface, whereby when securely tightened around the semi-elastic lower bearing housing, the at least partially-knurled surface of the clamp ring inner circumferential portion compresses into the semi-elastic lower bearing housing to securely mount the guard to the tool.
