Drill America 7/8"-48 HSS Plug Tap

This Drill America 7/8"-48 HSS plug hand tap cuts internal threads in through holes. It suits general machine tapping, CNC operations and manual use across a wide range of materials. The plug style starts threads easily and maintains alignment in thru-hole applications. It is not for blind holes that require bottoming taps.

Thermals noise and power draw

Hand taps generate heat only from cutting friction during use. Noise is limited to the sound of the tap engaging the workpiece and the driving tool. Power draw depends entirely on the machine or hand effort applied. No electrical ratings or cooling specifications apply to this cutting tool.

Upgrades and replacements

This tap replaces a worn or damaged 7/8"-48 plug tap in existing tool sets. The jump is worth it when the previous tap no longer cuts clean threads or shows excessive flank wear. It does not serve buyers who need taper or bottoming styles for the same thread size.

Questions about this item

How do I install the 7/8"-48 HSS plug hand tap, and what step do people often get wrong?

Secure the workpiece, select the correct drill size for the 7/8"-48 thread, then start the plug tap straight with steady pressure; the step most often missed is keeping the tap perpendicular so threads start square.

What maintenance or replacement will this 7/8"-48 plug tap need over time?

The high-speed steel cutting edges will dull with use; replace the tap when threads feel rough, require excessive force, or show visible wear on the flutes.

What limit appears first when using this 7/8"-48 plug tap continuously?

Chip evacuation in deep through-holes becomes the limiting factor — backed-up chips increase torque and can break the tap if not cleared frequently.
