Description:
Groove micrometer is a precision measuring instrument for accurately measuring internal or external grooves
and slots in machining,automotive applications. Available with measuring range including 0-25mm,25-50mm, 50-75mm,
75-100mm for metric measurement and 0-1″,1-2″, 2-3″, 3-4″ for inch measurement, groove micrometer ensures ultra-precise
dimensional verification for critical components.

Groove micrometer delivers reliable measurements even in hard-to-reach geometries. The friction thimble with 0.01mm graduation
for metric measurement and 0.001'' graduation for inch measurement, while the heat-treated steel frame ensures thermal stabilit
during prolonged use. Unlike digital type, the mechanical design eliminates battery dependency, making it ideal for continuous
shop floor operations.

Precautions:
1. Clean before use, wipe the measuring surfaces and grooves with a lint-free cloth to remove dust, oil.
2. Avoid temperature extremes, use in a stable environment, allow the tool to acclimate if moved between hot/cold areas.
3. Wipe dry after use, especially in humid or coolant-exposed environments.
4. Keep in the protective case when not in use.

Applications:
1. Machining: Measure internal grooves in shafts, bearings, and gears.
2. Automotive: Verify piston ring grooves, valve seats, and transmission components.
3. Aerospace: Precision inspection of turbine blade slots.
4. Quality Control: Ensure compliance with tight tolerance standards (ISO/DIN).
