## Questions & Answers

**Q: Where can I purchase a t-handle tap wrench that will accommodate the 21/64 shank size?**
A: Century Drill & Tool offers two options that would fit the 21/64" size.  Our t-handle tap wrench, item 98502, will work.  We also offer an adjustable tap wrench, item 98510, that would work.  Both are available for purchase here on Amazon.com.

**Q: Can this tap 316 stainless steel ?**
A: Hello, our carbon steel taps will cut stainless steel, but please use caution, as stainless steel can work harden. Make sure to use cutting oil and cut slowly.

**Q: For a 1/8 pipe tap my Snap On tap and drill chart calls out for a 11/32 drill bit , but  this says to use a 21/64 bit what is correct?**
A: The correct drill size depends on the thread engagement specification of the tap.  Century taps are rated for ~75% thread engagement, so 21/64 would be the best drill size.  Some taps are rated for ~50% thread engagement and may use a 11/32 drill.

**Q: What is the flute length of the 6-32 tap?**
A: 3/4"  actual threaded cutting length.
