### ⭐⭐ 







  
  
    Holes are too small. Here's a workaround...
  

*by D***N on Reviewed in the United States on March 5, 2018*

I'm not going to return this product because it costs more for postage than the price of the item. As others have observed, the holes are somewhat smaller than the sizes indicated, maybe due to the thickness of the paint. Here's a workaround I'm using: take the drill bit you want to measure and find the largest hole it will fit through. The correct size of that bit, therefore, is that of the next largest hole on the card. In other words, say for example, the largest hole that drill bit fits through is labeled 31/64". If so, you have a 1/2" bit, even though the bit won't fit through the 1/2" hole. It's a pain in the neck and, frankly, prone to error (I marked mine to remind me of the need to "measure up" to the next size), but it justifies keeping it in the shop and out of the trash can. For now anyway.

### ⭐⭐⭐⭐⭐ 







  
  
    Heavy duty, high quality gauge.
  

*by P***N on Reviewed in the United States on April 20, 2019*

Bought this to replace a plastic gauge I had. The plastic gauge was flimsy, and no longer accurate, due to wear thru use. The numbers were especially difficult to make out. This gauge is much heavier duty, appears to be accurate, and the embossed legend should remain legible for a long time.

### ⭐⭐⭐⭐⭐ 







  
  
    Nicely made
  

*by S***E on Reviewed in the United States on September 15, 2017*

There's not too much you can say about a drill gauge, but this one is well laid out and well constructed. The black painted finish and light colored lettering gives good contrast for viewing and the fact that they also give the decimal equivalent is an added plus.
