One more try. The drill bit is a plain ol run of the mill 25/64" (.3906) high speed drill bit. The kind everyone has in their set. The tap is a special one use only tap called a HeliCoil tap. As the coil itself is 3/8" x 16 on the inside, it is special on the outside and the tap is NOT a regular tap size. HeliCoil is a brand name and the kit you need is a # 5521-6. This contains the tap, coils and the insertion tool. For extra depth you may insert more than one coil.
Does this get it covered yet ?
