Review on Performance Tool W8662 Drill Combo by Keegan Herbert

Before opening the box I accidentally noticed that the drill included in this set has a 10.5 punch which indicates this that it is a 10-drill. 5mm. The correct drill bit for a 10 x 1.25 thread is 8.8mm, if I blindly opened this up and drilled holes my project would be screwed (no pun intended). With a hole 1.7mm larger than intended, the winding leaves virtually no engagement with the threads. Basically buying this product is a waste of time and money. Even the product description says that the correct 8.8mm drill bit is included, Revain quickly becomes a source of junk with no useful purpose.
