Stripped threads

My $20 Harbor Freight tap & die set has gotten a lot of use, mostly on aluminum. At that price you could buy two sets and chop down the tap on one set to make your own blind tap, if the need arose. When chopping it, you would have to be careful not to overheat and ruin the hardness of the steel.

I'm thinking a regular tap may work better because it will bind at the bottom making the fit tighter. This proved to be true when bolting flywheels to the shaft on my Homelite friction drive setups. The blind taps came out, the regular ones didn't.

Am I missing something? Why would you want your tap to bind in the hole being tapped?

Sorry. Not the tap. The stud. Tighter the stud holds the better.

Just drill n tap to a size up making sure it's course thread and red locktite. If one is already jacked then the others not far behind,.,.,.do 'em both! Keep it simple,. GL Stuk
