Hand Tap Chrome Alloy 1/4" BSCY (26tpi)

Product Description

Available in 3 leads:

Taper:  8 - 10 leads of thread used for starting new threads

Intermediate:  Less tapered, 4 - 5 leads,  used to follow a Taper tap or for restoring threads

Bottoming: Very little taper 1 1/2 - 2 1/2 leads, so will cut a new thread to the bottom of a blind hole, but the lack of taper makes starting a new thread difficult.
