Review on 45 Speed Steel Gauge for Gyros 22010 by Ben Barrington

This is a very good set. I bought it mainly for cleaning and raising small engine carburetor jets. The fact that they stand upright in their own exact sized holes is very handy for finding the right size. They're well sharpened, so if you're patient you can easily drill a slightly larger hole. When I received the kit, two bits were knocked out of their holes and one bit was broken, I believe due to rough handling by someone in the shipping process. I contacted gyros support and the rep quickly sent two bits. Although I will never use this particular racquet, I felt like I should have the complete set. Kudos to customer service. I have other microbits that don't compare to the sharpness and precision of this one. Using a digital caliper or micrometer to check size will tell the story with cheaper bits.
