## Questions & Answers

**Q: Where is this gauge manufactured?**
A: The gauge is made in CHINA not the US.  IRWIN prints "Huntersville, NC " in bold text on the package, but in small, skinny text it says "Made in China to IRWIN specifications".
On the gauge itself it says "Huntersville, NC" with no country of origin marking... in what appears to be an attempt to pass off their outsourced,  Chinese gauge as an American product.
Had I known the actual country of origin, I would have bought a Huot.
Amazon really should be addressing the country of origin themselves.

**Q: Is the lettering really etched in as described, or printed on with white paint?**
A: Thank you for choosing Rubbermaid Commercial. Our goal is to provide our customers with the highest quality and service. The Lettering and numbering will be both etched and painted on the Irwin 12092 1/16-to-1/2-Inch 29-Hole Steel Drill Bit Gauge

**Q: How thick is this tool?**
A: 8.4 x 3.7 x 0.1 inches

**Q: Is this suitable for sizing a wooden dowel?**
A: It doesn't have a cutting edge on the holes, so if you want to try sizing, you'll need to only be having off a small amount.  Of course, there are a bunch of holes in 1/16" increments.

### ⭐⭐⭐⭐⭐ Steel Drill Bit Gauge
*by C***. on May 27, 2013*

I have other, cheaper drill bit gauges but I really like this one. The plastic versions are cheaper but the plastic will wear over time and not be as accurate. And some of the plastic gauges don't have particularly clean and crisp holes. This gauge is very well made. The hole exactly matches the largest SAE drill bit that will just fit into the hole. You can use it to sort your drill bits. What I use it for is to quickly select the appropriate drill bit for a screw or a rivet. You just find the hole that the screw or rivet fits through with just a bit of clearance and then use that size drill bit. I hang this next to my drill press.
