Westward #8-32 UNC Taper Hand Tap

This new Westward hand tap cuts #8-32 UNC threads in a through hole or a blind hole. The carbon steel body has a bright uncoated finish and a right-hand thread direction. A taper lead helps start the cut smoothly. It suits general purpose threading in steel or non-ferrous metals.

Threading jobs needing a #8-32 UNC starter tap

Machinists and maintenance technicians who need to create new internal threads or clean damaged ones will find this taper tap fits the task. The 2.13 in overall length and 0.75 in thread length give adequate reach for common hole depths. Builders who require a bottoming or plug chamfer for threads close to the bottom of a blind hole should look at a different tap style.

#8-32 UNC thread size with taper chamfer

The single specification that decides fit is the #8-32 UNC thread size combined with the taper chamfer. This tap only produces that specific diameter and pitch. If the drawing calls for a different thread series, a different diameter or a different class of fit, this tool will not produce the required thread.

Questions about this item

How often will the #8-32 UNC taper tap need to be replaced when threading carbon steel?

Replacement depends on hole volume and material hardness; the uncoated carbon steel cutting edges wear faster than coated taps, so inspect thread quality after each batch and replace when gauge checks show oversize threads.

What limits how many holes I can tap continuously with this 2.13 in overall length tool?

Chip evacuation in the straight flutes becomes the bottleneck; the 0.75 in thread length holds only a small chip volume, so deep or repeated cuts require frequent reversal to clear chips and avoid breakage.

How much heat builds up in the bright finish tap during all-day production tapping?

The uncoated surface generates more friction heat than coated alternatives; use cutting fluid and pause between holes to keep the carbon steel body from annealing and losing hardness.
