Drill America 7/16"-48 HSS Plug Tap

This high-speed steel hand tap cuts internal threads in a 7/16"-48 size. It suits general machine tapping, CNC operations, and manual work across most common materials. The plug style is designed for through-hole applications where the thread does not need to reach the bottom. It serves mechanics and fabricators creating fine-pitch connections in metal components.

Plug style for through-hole threading

The plug chamfer starts the thread square with the workpiece and pushes chips forward through the hole. This geometry prevents binding in through holes but cannot cut threads to the bottom of a blind hole. Users needing full-depth threads in closed-end holes must select a bottoming tap instead. The high-speed steel construction resists wear during repetitive hand or powered use.

Fine 48 threads per inch pitch

The 48 TPI pitch produces a shallow thread profile that offers less load-bearing area than coarse alternatives. It requires precise alignment and lubrication to avoid cross-threading or tap breakage in harder alloys. The tap decimal equivalent is .4375 inches, so the drilled hole must match this specific diameter for correct thread engagement. Buyers needing standard coarse threads or larger diameters cannot use this tool.

Questions about this item

When will the HSS cutting edges on the 7/16"-48 plug tap need replacement?

The high-speed steel threads resist wear during general machine or CNC tapping; replace the tap once the flutes no longer cut cleanly in through holes.

What limit appears first when the tap runs continuously in a 7/16"-48 hole?

Chip evacuation in the plug-style flutes becomes the limiting factor during sustained through-hole tapping.

How much heat does the 7/16"-48 HSS tap generate during all-day use?

Cutting heat stays manageable with proper lubrication; the tool itself has no motor or electrical draw.
