There are two types of cone gauges: metric and Mohs. The metric cone gauge has 8 specifications: 4, 6, 80, 100, 120, 140, 160, and 200. The specification number is the millimeter of its large end diameter D. For example, the large end diameter D of the metric cone gauge No. 4 is 4MM The Mohs taper gauge has 7 specifications, including 0, 1,..., and 6. Specification 0 has the smallest size, while specification 6 has the largest size.

Cone gauges are divided into two types: those with flat tails and those without.

Cone gauges are divided into two types based on their tolerances: high-precision and ordinary precision. High precision cone gauges are used to inspect the taper of spindles and holes in machine tools, precision instruments, etc., and ordinary precision gauges can be used.
