Dawson Precision Ejector Pin Drill Bit uses it’s counter clockwise cutting edge to keep the ejector pulled tight 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.

  • Fastest and easiest way to fit an ejector to a frame
  • 0.06250 inch for use with 1911 frames
  • 0.09375 inch for use with 2011 frames

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 sharp object into the ejector pin hole and mark the spot on the ejector. Next 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. Repeat again and again until the pin fits. It’s a pain in the butt and hard to get a perfect fit. But now there’s a simple, easy way that you’re gonna love. Using the Dawson Precision Ejector Pin Drill Bit, just install the ejector into the frame, chuck the drill bit into your hand held reversible drill and (very carefully) with very little force, let the drill bit do the work and drill through the ejector pin hole from the RIGHT side of the frame with the drill SET TO REVERSE. This allows the ejector pin hole to act as a drill guide. Now the cutting edge only contacts the post on the ejector and since its rotating counter clockwise it actually pulls the ejector tight into the frame.

  6. 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.

  7. Works like a charm!

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

  8. 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!

  9. Confidence to do it yourself

    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. .
