Drill America 1/4"-64 HSS Plug Hand Tap

This Drill America HSS plug hand tap cuts internal threads in metal workpieces. It suits general machine tapping, CNC operations and manual use. The tool handles through-hole and blind-hole conditions across common materials. It is not for buyers who need a taper or bottoming tap style.

1/4"-64 thread size and plug chamfer

The tap is sized 1/4"-64 with a plug chamfer design. This specification decides whether the tool matches the required hole and thread standard. The plug style is generally used for through holes and starts threads square with the workpiece. Select a different chamfer if the hole is blind or requires full-depth threads.

California Proposition 65 chemical notice

The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm. This notice informs safe handling practices in the workshop. No bundled accessories or software are included with the tap.
