7/32-20 BSW High Speed Steel (HSS) Tap & High Carbon Steel (HCS) Die Set, Stanley Plane Restoration Tools
A taper tap is best for starting and threading a new hole due to the extended chamfer. If your budget allows for only one tap, I recommend a plug tap. A plug tap will let you start and thread a new hole and also allow threading a blind hole to within ~1/4" of the bottom. A bottom tap allows chasing and tapping threads very close to the bottom of blind holes. This Plug Tap will allow threading a blind hole to within ~1/4" of the bottom. All taps and dies can be used for chasing. Chasing is the process of rethreading damaged, rusty or paint filled threads.
British Standard Whitworth aka BSW is a 55 degree thread angle used by Stanley on this size thread
7/32-20 is the direct fractional replacement for #12-20
Cutting fluid reduces friction and helps produce smoother threads. *** Please wear your safety glasses ***
