Ejector Pin Drill Bits

    If you’ve ever installed an ejector onto a 1911 or 2011 frame you know it’s a pain in the butt. First, you have to install the ejector into the frame. Then you have to stick a pen into the extractor pin hole and mark a spot on the ejector. Then you have to take out the ejector and file that spot with a needle file. Put the ejector back in and check the pin's fit. Then remove the pin and the ejector and file some more. Repeat until the pin fits. It’s a pain in the butt. But now there’s a simple, easy way that you’re gonna love. Using our new Dawson Precision Ejector Pin Drill Bit, just install the ejector into the frame, chuck the bit into your hand held drill and (carefully) drill through the ejector from the left side with the drill SET TO REVERSE. Our EPDB (Ejector Pin Drill Bit) uses it’s left-hand cutting edge to keep the ejector torqued into the frame during the drilling process. Using a standard drill bit will push the ejector up and away from the frame during drilling causing a loose fit.

    4. Wish I had found these sooner

      I read about the idea of using a left-hand twist bit online. So I tried it with an import bought from Amazon. That pistol now has a cheap Chinese drill bit serving as the ejector pin since it broke off just as it broke through drilling the pin leg. When it comes loose, and it will, I will drill it out with a carbide drill, ream the hole to 3/32 and use an STI pin. All this is to say, use a good quality Dawson bit in the first place and save yourself the PITA.

    5. Works like a charm!

      Easy to use. Great results. Glad I bought this drill bit.

    6. Works as described - Great for DIY build

      Posted by JMc on Jan 28th 2016

      Created a perfect fit in just one pass with this bit. Left hand twist worked like a charm to pull down on the ejector. No removing ejector multiple times and using a file to get the right fit. From set up to finish took me less than 3 minutes. Great IDEA!

    7. Confidence to do it yourself

      Posted by Ray Parker on Dec 9th 2015

      I was a little apprehensive to do this because most parts dealers do not recommend drilling thru ejector hole in frame. But after watching utube video, I pulled the trigger and bought the bit. Sure glad I did, bit cut the half moon cut like butter. Would recommend almost anyone can do this their self. .

    8. Easy to use!

      I bought this against the advice of some 1911 experts. Glad that I did. Easy to use and it works like the video shows!

      Simply the easiest most efficient way to pin a new ejector. Great product but go slow and don't push to hard. Let the bit cut.
