Any idea why there are so few options for drilling micro pocket holes? Kreg obviously has the conversion pieces for their larger jigs, but it seems like that's it. There don't even seem to be any of the plethora of cheap, import pocket hole jigs that use a 7.5mm step drill like the Kreg conversion.
I did cut some sleeves out of 3/8" OD aluminum tube that fits closely around the Kreg micro drill bit and slid them inside the drill bushings of my Harbor Freight pocket hole jig. While that does work, the aluminum is getting pretty beaten up and slides out with the bit, and I'd like a more permanent solution.
