Point Micrometer 50 - 75mm | 15°
SERIES 327
SERIES 327
A point micrometer is a specialised type of micrometer designed to measure small features like the diameter of grooves, narrow recesses, or other delicate geometrical elements on a workpiece. Unlike standard micrometers, the point micrometer has sharp, conical measuring tips (points) that allow it to access and measure fine details that would be difficult or impossible to measure with flat anvils.
Key Features of a Point Micrometer:
- Graduation 0.01mm
- Clutch on the shank
- Hard metal stems with 15° or 30° angle
- Ideal for groove measurements
- Check rods (excluding 0-25mm)
Key Features of a Point Micrometer:
-
Pointed Anvil and Spindle:
- The defining feature of the point micrometer is its pointed anvil and spindle, which usually have sharp, conical ends. These points allow the micrometer to fit into very narrow grooves, small steps, or indentations on a workpiece.
- The tips usually have an included angle, commonly 15 degrees or 30 degrees, to allow for precise entry into small spaces.
-
Applications:
- Groove diameter: Commonly used to measure the diameter of narrow grooves or slots in parts like shafts, gears, or other mechanical components.
- Thread root measurement: Used to measure the root diameter (the smallest diameter) of threaded components.
- Small spaces: Ideal for measuring dimensions in tight or awkward spaces where a standard micrometer wouldn’t fit.
-
Accuracy and Precision:
- Point micrometers offer high accuracy and precision, depending on the model and manufacturer.
-
Ratchet and Thimble:
- Point micrometers are equipped with a ratchet mechanism on the thimble to ensure consistent and repeatable pressure during measurements, helping to reduce operator error.
-
Durability:
- The points of the micrometer are often carbide-tipped for added durability and wear resistance, especially when measuring hard materials.
- The micrometer body itself is typically made from stainless steel or other tough materials, ensuring it can handle frequent use in industrial or workshop settings.
