Drill America 3/8"-14 HSS Plug Hand Tap

This high-speed steel plug hand tap cuts 3/8"-14 threads in through holes. It is suited for general machine tapping, CNC operations, and hand use across a wide range of materials. The plug style starts the thread square with the workpiece for reliable engagement.

Hand-operated threading tool for through-hole

The tool produces threads by manual or powered rotation without integrated cooling or lubrication systems. Heat generation and noise levels depend entirely on the operator's technique, cutting speed, and the workpiece material. No power-draw specifications apply to this non-powered cutting instrument.

Sustained cutting in blind or deep through holes

Continuous use in harder materials increases friction and heat at the cutting edges, requiring the operator to manage chip evacuation and apply cutting fluid regularly. The HSS construction maintains hardness during extended operation, but thread quality relies on consistent pressure and alignment rather than automated feed control.

Questions about this item

How do I start the 3/8"-14 HSS plug tap straight in the hole?

Use a taper tap first to start the thread square with the workpiece, then follow with the plug tap for through holes; skipping the taper step often leads to crossed threads.

When will the 3/8"-14 HSS tap need replacement?

Replace the tap when cutting edges dull, threads gauge oversize, or chips clog flutes despite lubrication; high-speed steel wears faster in abrasive alloys.

What limits sustained tapping with this 3/8"-14 HSS plug tap?

Heat buildup in the high-speed steel cutting edges reduces hardness and causes premature wear during continuous power tapping without coolant.
