i own a race shop and we have snap on with the special coatings < very hard to use and will brake in a flash < But after learning to use them their is nothing better, you also have to take a loan to own

I also have a Hanson set real strong not very expensive good production units and the taps come in point type, standard everyone sells, and bottom type to extend the thread all the way - industrial supply house stuff made in the USA

and we also have craftsman good for what you are looking to do, Quality is good they the taps and dies work well the drivers are not up to speed but it will do anythoing you need -- cheap as this stuff goes

in the machine shop we have many 2 / 3 and 4 type flute taps as well as other specials for different work and a 2 flute does not stick as much as a 3 or 4 BUT the key is to buy a real good tapping fluid just like motor oil and a lot of stuff today tapping fluids can also be china crap -

trick to tapping we inploy is a tapping block its nothing more than a steel block to help keep the work straight not always possable to use under a hood - also when tapping always hold what you are doing as straight as possable and only turn by hand in 1/4 of a turn and than reverse 1/2 turn to un hook the chips from cutting -- hope that helps -

the cheap china stuff will brake off in what you are doing and it will , cost the price of a snap on set to have some one fix it for you -- only by good stuff junk is just that - jz
