If you need to determine the size of a hole, this 51-piece drill blank set from RS PRO has a large variety of blanks suited to the task.

Made from high-speed steel, which gives the blanks a high hardness rating and resistance to abrasion, the set is housed in an easy-to-carry metal indexing box. For a high level of precision and accuracy, the 51 drill hole gauges increase in diameter by 0.1 mm increments and range in size from a diameter of 1 mm to 6 mm. The slots in the box for each drill blank are labelled for size, and every piece above 3 mm in diameter is also marked with its size for additional ease of identification.

As well as determining the dimension of a hole, these drill blanks can be used in the manufacture of special cutting tools.
