Drill America 3/8"-56 HSS Plug Hand Tap

This Drill America hand tap cuts a 3/8"-56 thread using high-speed steel construction. It suits general machine tapping, CNC operations and manual threading tasks. The plug style is intended for through holes in a wide range of materials. It is not for blind holes requiring full thread depth to the bottom.

California Proposition 65 chemical warning applies

The product carries a California Proposition 65 notice for substances linked to cancer and reproductive harm. No thermal, noise or power draw data is provided for this hand tool. Normal use involves manual or powered rotation without electrical consumption or cooling requirements.

High-speed steel plug tap for through holes

High-speed steel offers wear resistance during repetitive threading work. The plug taper starts threads squarely in through holes but does not reach the bottom of blind holes. Users needing bottom-thread engagement must select a bottom-style tap instead.

Questions about this item

How do I install the 3/8"-56 plug tap and what step is often missed?

Drill the correct tap-drill hole first, then turn the plug tap straight into the hole with a tap wrench; the step most people miss is using cutting fluid and reversing frequently to break chips.

What maintenance or replacement will the HSS tap need later?

The high-speed steel cutting edges dull with use; when threads become rough or oversize, replace the tap — there is no sharpening service for this size.

What limit appears first during sustained tapping with the 3/8"-56 tap?

Chip packing in the flutes is the first limit; if chips are not cleared by frequent reversal and lubrication, the tap can bind or snap in the hole.
