Value Collection 91-338-4 Tap Guide 10 to 1 Inch

Product Description

The VALUE COLLECTION 91-338-4 is a tap guide designed to keep hand taps running straight and true during threading operations. It accepts taps ranging from size 10 up to 1 inch, covering a wide range of common fastener sizes. The guide measures 3 inches in overall length with a 0.25 inch shank diameter, providing a stable reference point against the workpiece surface. Machinists, pipefitters, and maintenance technicians use tap guides to reduce cross-threading and broken tap risk when tapping holes by hand. Weighing 0.25 pounds, the tool is lightweight enough for frequent bench or field use.

This tap guide is suited for hand-tapping operations in metal fabrication, maintenance, and repair applications where a drill press or CNC machine is not available. It is particularly useful when tapping holes in place on installed equipment or structural components where perpendicular alignment is difficult to maintain by feel alone. Any trade that regularly threads fasteners into metal stock or equipment housings will find this tool useful for consistent, on-center tap starts.

Installation Notes

This tool is used by machinists, pipefitters, maintenance technicians, and other trades performing hand-tapping work. Place the guide against the workpiece surface and seat the tap shank into the guide bore before applying turning force. No power source is required. Keep tapping fluid or cutting oil on hand to extend tap life and improve thread quality during use.
