Quick sizing of any twist drill from 1/16-1/2" by 1/64". 29 Holes marked with drill size in inches and decimal equivalents. Rigidly tested after hardening. Black matte finish with gauge information steel stamped on one side and white marked on reverse for quick, clear reading.
Based on my observations, this industrial drill bit is a true game-changer. It is incredibly durable and lives up to the expectations of even THE most challenging projects. The precision and accuracy of the bit are unmatched and have saved me time and effort on numerous occasions .However, the only downside is its hefty price tag, but the quality justifies the cost. Overall, I highly recommend this top-of-the-line cutting tool to anyone in need of reliable and efficient drilling..
That's what I expected from a quality tool from Starrett. I will use it as a quality control gauge to check the outside diameter of small parts. These Starrett pressure gauges are extremely accurate compared to the cheaper versions.
