A tip I saw in a magazine a few weeks back (and haven't tried) for
sharpening dull reamers was to run a carbide-tipped lathe tool (about
\pounds 5.00 if you don't have one) along the flutes of the reamer (up
under the flutes I guess). Apparently, this will put the edge back on.
Someday I will have to try that.
Were you saying that Xcellite used to do them in the 99 range? They're
now listing tamperproof Torx in a couple of sizes.
I have gotten rather frustrated with Xcellite over the last 10+ years
because they are so slow to come out with new stuff. All of my tamperproof
bits are other MFG.
