The body forms an inner passage between the first open end and the second open end. The passage is configured to receive a portion of a tool. The body has a plurality of spaced slots. Each slot extends from the first open end a select distance to the mid portion of the body. The body has a port and a plurality of openings proximate the second open end to allow air or fluid passage.
Claims20
A guard assembly comprising:
- a housing having a first open end, a second open end and a mid portion between the first open end and the second open end;
- the housing forming an inner passage between the open first open end and the second open end, the passage configured to receive a portion of a tool;
- and
- the housing having a plurality of spaced slots, each slot extending from the first open end a select distance to the mid portion of the housing;
- and the housing having a port and a plurality of openings proximate the second open end to allows air or fluid passage.
A guard comprising:
- a cylindrical body having an open first end and an opposed open second end, the body forming an inner passage between the open first end and the open second end, the first open end of the body configured to receive a portion of a tool, the body further including at least one opening proximate the second end to allow air flow, the body further having a suction passage through the body proximate the second end;
- and
- a suction port in fluid communication with the suction passage, the suction port configured and arranged to be coupled to a vacuum system.
A microstop guard comprising:
- a cylindrical body having a first open end and an opposed second open end, the body forming an inner passage between the first open end and the second open end, the inner passage including an inner ridge extending inward from the inner passage proximate the first open end of the body, the inner ridge configured and arranged to snap fit the guard to a portion of a microstop-containing tool;
- the body further including a plurality of spaced, parallel slots, each slot extending from the first open end a select distance in the mid portion of the body;
- the body further having at least one opening proximate the second end to allow air flow and visibility to the microstop, the body further having a suction passage proximate the second end and generally opposite the position of the at least one opening;
- and
- a suction port in fluid communication with a suction passage, the suction port configured and arranged to be coupled to a vacuum system.
