Yecch. Tri-wing bits. I hate the blasted things -
What's the big deal with just taking an old bent or broken tip
screwdriver and grinding it down to the proper shape?
My machinist friend would remind you to quench the metal in
water periodically so as to keep the temperature down, and
keep the metal at a good strength.
That's all it has to take to get your own Tri-wing removal tool:
screwdriver, grinding wheel, cup of water.
