| There are a number of types of micrometer intended for specific measuring tasks. | ||||
Blade micrometer |
||||
 |
The anvil and spindle of blade micrometers are blade-shaped so that hard-to-reach dimensions such as the diameter of a narrow external groove can be measured. | |||
Disc micrometer (rotating) |
||||
 |
The measuring faces of disc micrometers are disc-shaped to allow the measurement of shrouded features such as gear teeth.
This micrometer is ideal for the measurement of root tangent length of spur and helical gears. |
|||
Tube micrometer |
||||
 |
Tube micrometers are designed to measure the wall thickness of tubing.
The measuring surface of the anvil is spherically curved instead of flat, allowing a single point contact with the item being measured. Tube micrometers are also available with spherical anvil and spindle measuring surfaces. |
|||
Screw thread micrometer |
||||
 |
Screw thread micrometers are used to measure the pitch diameter of a screw.
The pointed spindle and double-v anvil are designed to contact the screw thread. |
|||
V-anvil micrometer |
||||
 |
V-anvil micrometers are useful for measuring the outside diameter of cutting heads with three flutes such as twist drill bits or reamers. | |||
Sheet metal micrometer |
||||
 |
The large throat of the sheet metal micrometer makes it an ideal tool for measuring the thickness of a large piece of sheet metal away from the edge. | |||
Paper gauge micrometer |
||||
 |
The paper gauge micrometer is a non-rotating type of disc micrometer designed to accurately measure the thickness of paper, cardboard, rubber or plastic sheeting.
It incorporates discs similar to the disc micrometer above. The spindle, however, does not rotate. This reduces the risk of compressing the measured item. |
