Shop Tip #351

Don't buy "carbon
steel" taps from your local hardware store or anywhere else. Instead,
get "high speed steel" ones from a machine tool supplier. They
won't cost you more, and they are WAY worth the effort. They cut better,
last longer, and are harder to break. I especially like the "spiral
point" taps like the one on the left.
