1/16"-64 Plug Hand Tap

This Drill America tap cuts internal threads in a 1/16"-64 size. It is made from high-speed steel for hand use or powered tapping operations. The plug style is designed for general use in through holes. It suits maintenance, repair and general machine tapping tasks.

For through-hole threading in common materials

Machinists and technicians cutting threads in through holes will find this plug tap appropriate. It works across a wide range of materials under hand or CNC power. Buyers who need to thread blind holes to the bottom should look at a bottoming tap instead. Those requiring a taper tap for starting threads squarely will need a different style.

Plug style for through holes

The plug chamfer is the single specification that defines this tap's primary use case. It is engineered to cut threads effectively in through-hole conditions. A taper or bottoming chamfer would be required for different hole types or starting requirements. This style determines whether the tool matches the specific threading job.

Questions about this item

How do I start the 1/16"-64 plug tap straight in the hole?

Use a tapping guide or keep the tap perpendicular while turning the handle slowly; the plug chamfer helps alignment but the first few threads set the angle.

When will the HSS cutting edges need replacement?

Replace the tap when threads feel rough, require excessive torque, or show visible chipping on the flutes; HSS dulls gradually in steel and faster in abrasive alloys.

What limits continuous tapping with this plug tap?

Chip packing in the flutes builds heat and torque; clear chips every few turns and use cutting fluid to delay the limit.
