## Questions & Answers

**Q: Which guide is correct for fitting a 9/16’s drill bit?  The 9/16’s on this one is 43/64’s.**
A: Good question! STI-UNC100SNP has the 9/16's marked  over the biggest hole.
Hope this helps. We have them in stock.

**Q: Are there 2 tap guides available one for unc & 1 for unf?**
A: Basically it's a guide for SAE sized bolt or drill bits. The walls inside each hole are smooth. This one is not for metric. I bought this to sit on a surface that I will drill to keep my drill hole straight. It will sit on a flat surface as well sit perfectly on a corner. For example when installing a handle on a cabinet with a hole drilled in at a slant will cause the handle to not position flush to the surface when installed looking like a jank ass been slopping things up in there...

**Q: Why are the guide holes so much larger than nominal?  nominal=>measurements: 1/2=>.608, 7/16=>.532, 3/8=>.458, 5/16=>.391, 1/4=.318**
A: Can I use a tap guide as a drill guide?
No, the tap guide is sized for tap diameters. The drill guide is sized for drill bits. There is a difference and if you attempt to use the tap guide as a drill guide there will be slop and inaccuracy.

**Q: Are these thread? can i put threaded npt to check tap?**
A: Good question! Sorry these are not threaded. The holes are a Tap Guide.
Hope this helps. We have them in stock.
