the housing having a plurality of spaced slots, each slot extending from the first open end a select distance toward the mid-portion of the housing, the plurality of slots defining a plurality of pliable fingers therebetween, wherein each of the plurality of pliable fingers is configured to independently engage an outer surface of a housing of a tool to retain the guard assembly on the tool;
the housing having a port and a plurality of openings proximate the second open end to allow air or fluid passage; and
the housing having a radially protruding portion of the housing defining a ring integral with the housing, the ring extending around the outer circumference of the housing of the guard assembly, the ring being positioned between the plurality of spaced slots extending from the first open end the select distance toward the mid-portion of the housing and the plurality of openings proximate the second open end.
2. The guard assembly of claim 1 , further adapted to be connected to a microstop countersinking tool.
3. The guard assembly of claim 1 , wherein the port is configured and arranged to be connected to a suction source.
4. The guard assembly of claim 1 , wherein the plurality of openings is sized to prevent fingers from being able to pass through.
5. The guard assembly of claim 1 , wherein each of the plurality of slots is substantially parallel to each other, and wherein only the plurality of pliable fingers are configured to retain the guard assembly on the outer surface of the housing of the tool.
6. The guard assembly of claim 1 , wherein the guard assembly comprises at least one feature on a portion of the housing defining the inner passage, the at least one feature configured to removably engage with a complementary feature on the outer surface of the tool to snap-fit the housing on the tool.
7. The guard assembly of claim 1 , wherein the guard assembly is made of one of polyethylene, polypropylene and polycarbonates.
8. A guard, comprising:
a single, monolithic 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 open first end of the body configured to receive a portion of a tool, the body further including at least one opening extending through an outer circumferential wall of the cylindrical body in a radial direction of the cylindrical body proximate the open second end to allow air flow, the body further having a suction passage through the body proximate the open second end, and a ring portion integral with the body and extending around the outer circumferential wall of the body at generally a mid-point of the body between the first open end and the second open end and between the suction passage through the body and the open first end of the body; and
the body defining a suction port in fluid communication with the suction passage, the suction port configured and arranged to be coupled to a vacuum system.
9. The guard of claim 8 , wherein the suction passage radially opposes the at least one opening about a circumference of the cylindrical body of the guard.
10. The guard of claim 8 , further comprising:
the body having a plurality of slots, each slot extending in the body from the open first end a select distance.
11. The guard of claim 8 , further comprising:
at least one 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 the portion of the tool.
12. The guard of claim 8 , wherein the suction port is elbow-shaped.
13. The guard of claim 8 , further comprising:
the body further having a rounded groove extending in a select distance from the first open end to allow visualization of a depth indicator mark on the tool when the guard is coupled thereto.
14. A microstop guard, comprising:
a monolithic 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 microstop 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 a mid-portion of the body, the body configured to directly engage around a portion of an outer surface of a housing of the microstop-containing tool at the plurality of spaced slots, the plurality of slots defining a plurality of pliable fingers therebetween, wherein each of the plurality of pliable fingers is configured to flex outwardly in order to receive the portion of the outer surface of the housing of the microstop-containing tool within the cylindrical body and to directly and independently engage with the portion of the outer surface of the housing of the tool to retain the microstop guard on the microstop-containing tool solely with the plurality of pliable fingers;
the body further having at least one opening proximate the second open end to allow air flow and visibility to the microstop guard, the body further having a suction passage proximate the second open end and generally opposite the position of the at least one opening; and
the body defining a suction port in fluid communication with a suction passage, the suction port configured and arranged to be coupled to a vacuum system.
15. The microstop guard of claim 14 , wherein the body exhibits a gripping feature extending around at least a portion of an outer circumference of the body and positioned between the plurality of slots proximate the first open end and the at least one opening proximate the second open end.
16. The microstop guard of claim 14 , wherein the at least one opening proximate the second open end is circular having a diameter of 0.1 inch to 0.4 inch.
17. The microstop guard of claim 14 , wherein the micro stop guard is made of one of polyethylene, polypropylene, polycarbonate, nylon, acetal resins, acrylonitrile butadiene styrene and polyvinyl chloride.
18. The microstop guard of claim 14 , wherein the body is made by injection molding.
