I am going to try and tap a 7/32" BSW countersunk screw 10 mm long
I have found the following dies:
'7/32 BSW dies' (http://www.tap-die.com/contents/en-uk/p516_7-32_BSW_dies.html )
'Rotagrip - 04) 7/32 x 24 BSW HSS Die 13/16\" Diameter' (http://tinyurl.com/pzecw2y )
A couple of questions:
1. Which blank can I use? 2. I have a 25mm die holder from a metric tap and die set. Do I need to get a 13/16" die holder for the dies above?
