Threaded-hole tooling

The Drill America 1/4"-72 HSS plug hand tap cuts internal threads in a range of metals using high-speed steel construction. It suits mechanics, fabricators and maintenance teams who need reliable thread creation for repair or assembly work.

Plug-style cutting geometry

The plug chamfer leads the tap cleanly into through-holes and starts threads square with the workpiece. High-speed steel resists wear during repeated use in steel, aluminium or brass without the rigidity demands of a taper or bottoming tap.

California Proposition 65 notice

The product carries a Proposition 65 warning for exposure to chemicals linked to cancer and reproductive harm. Users should follow standard shop hygiene such as wearing gloves and washing hands after handling the tap.

Highlights

Questions about this item

What does the 1/4"-72 thread size mean for hole preparation?

The 1/4"-72 designation indicates a quarter-inch nominal diameter with 72 threads per inch, requiring a specific drill size to create the correct minor diameter before tapping.

What shank dimensions does this tap have for holder compatibility?

As a 1/4" hand tap it follows standard fractional sizing, so the shank fits common tap wrenches and adjustable handles sized for quarter-inch tooling.

How do you start the plug tap correctly to avoid cross-threading?

Apply the taper-style start square to the workpiece, use steady pressure with a tap wrench, and reverse frequently to break chips in through holes.
