Review on Drill Angle Gauge Sharpener Inspection by Carta Gutierrez

This set of drill angle jigs turned out to be significantly stronger than I expected from the photos - they are heavy gauge stainless steel and extremely durable. The sensors are also physically larger than I expected - the largest sensor is roughly 3" x 4". The markings are engraved so they don't rub off. Chinese characters are read as "chevron patterns" on a small polygonal gauge. I haven't checked the angles but I assume they are accurate. This set far exceeded my expectations and should last a lifetime.
