I don't think you need a carbide bit.Receivers aren't that hard.
This supplier has the tap...........http://www.mscdirect.com/browse/tnpla/03294881?src=pla&cid=PLA-Google-PLA+-+Test&CS_003=7867724&CS_010=03294881........... and drill for less than $8 ...before shipping. |

I agree the drill bit is likely not as important. I'm mostly concerned with the thread tap. I've read stories where people claim to have easily broke cheap ones off in their receiver. I'm pretty experienced with tapping threads. I've done it in stainless steel, steel, aluminum and plastics, but I don't recall drilling & tapping 4 holes that were this important to me. I don't want to screw it up. The thread tap I found at MSCDirect for $3.33 says: to be generally for soft, durable metal. It is commonly used for general purpose applications on abrasive materials, nonferrous materials, plastics and wood. That sounds a bit on the weak side to me. |

For a one off job I would just buy a recognizable brand for the tap, as far as the bit, look at a table that has bit and tap sizes and go to the local hardware store. I think the 6-48 Is a #31 without looking.
As far as breaking taps, they should be used properly and not like you are screwing on to a hose bib. A little care will go a long way. http://www.rem870.com/2013/10/30/drilling-and-tapping-remington-870-receiver-to-install-rail-or-ghost-ring-sights/ |

I just went with the cheapo MidwayUSA drill bit & tap. Will use generous amounts of lube, go slow, back it off often and keep the tap clean. Should work out fine.

True. The receiver is not hard metal and you can drill all the way through (so you avoid tapping a shallow, blind hole) Will you drill the receiver with a drill press (or mill) with a vise? If so, use the chuck to steady and support the tap so you do not push it sideways and you'll do fine. In my experience more small taps are broken from lateral pressure to the side than from twisting |

Having done 3, lube and don't, I say DON'T go more than 1/4 turn without backing out and using air to blow out hole and tapp. Get a good Tapp

My local non-big box hardware stored has all taps behind the counter. I have bought crazy 5-40 and other weird shotgun bead taps there that worked out great including the number drills.
Marking the holes is the key especially if theres fluting or serration on the top of the receiver that will make your punch or drill go wonky. Use a drill press too |

If you don't know how to tap, technique is going to be more important than how much you spend on your tap.
Use proper lube. Get the tap started and reverse it every turn to snap off the cut material. If you are going deep, be sure to pull the tap out and clean the flutes a time or two and re-lube. The taps I have used on the Remingtons came with a drill fixture from Scattergun Tech. It is just a jobber quality tap, nothing special. |
