For those of you who complained this tap bit breaking on the first use and giving this item one star is because you don't know how to use a tap. I bought this bit and tap 3 bolt catch pin hole in the same day. Each time I used it, it cuts even better! The price is better than most seller and most companies. Works perfectly for my specific need. I highly recommend this.

I had to modify this to make it actually tap further by thinning the shaft extension otherwise I couldn't tap as far as was needed and that is beyond the cutter part of tap. I was hoping this would arrive and allow me to tap 5 inches and it wouldn't with out modification to the shaft. out of box the tap will stop at the end of the cutter. I made mine work though by thinning the extended shaft.

have an old forged lower with the roll pin? this tap with the companion drill bit will let you upgrade to the screw pin.

I don't like roll pins on AR lowers so I will use the appropriate tap drill and tap for the 6-32 pins that Aero Precision provides for their M4E1 lowers. This tap allows you to reach behind the rear lower for full rotation and better alignment. I've used it at least half a dozen times and still sharp; I use cutting lubricant even though it cuts aluminum like butter. I cut almost all the way and use the screw to swage the last thread or two for a tight fit.

Very Very weak, lasted less than 1 minute, snapped it off at threads with very easy wrist pressure chasing threads. shaft is 1/2 inch just pass the threads. As a machinist with 30 plus years experience I can say this is JUNK.
