Taps are well made and perform well. One design feature that is missing, however, is a center hole to accommodate a tap follower. For my use this is a noteworthy negative of this product. If they had a center hole I would have given 5 stars.

Worked great!
These bits worked great for me, for my small job of getting 2 holes in 3/16 soft steel. My first purchase of IRWIN HANSON 1/4" - 20 NC Tap and 13/64" Drill Bit Set, 80230 led to the (only) bit breaking in seconds, total frustration and waste of time. No issues with these bits, go in a little, backup, blow out shavings, and repeat. And of course use cutting fluid. Forney 20857 Tap Magic Industrial Pro Cutting Fluid, 4 oz worked great for me. Easy work, it is so much better with the right tools like this one.
