30-40mm Pistol-grip Three-point Internal Micrometers For Precise And Measurements In Tight Spaces For Easy Reading
Precision measurement tools designed for accurate bore measurements in tight spaces and hard-to-reach locations.
Product Overview
The pistol-grip three-point internal micrometer enables one-handed operation, making it ideal for measuring in confined spaces and suitable for batch measurements. The three-point contact system ensures superior accuracy and stability when measuring both blind and through holes, effectively minimizing measurement errors.
Key Features
- Self-centering 3-point design for accurate bore measurement
- Ability to measure closer to the bottom of blind bores
- Carbide-tipped contact points with ratchet stop
- Optional digital indicator (fixing bore: φ8mm or 3/8")
- Supplied with setting rings for measurements within 100mm
- Includes fitted protective case

Applications
Pistol-grip three-point internal micrometers are primarily used for measuring holes and slotted holes. They are widely applied in machinery manufacturing, automobile manufacturing, aerospace, electronic components, and other industrial fields. Their high measurement accuracy, ease of use, and simple operation make them essential tools for bore diameter measurement.
Usage Guidelines
- Avoid applying excessive force during measurement to maintain precision
- Do not disassemble the instrument
- Keep the instrument clean and dry
- When installing measuring jaws, pull back the grip and insert jaws into grooves sequentially
- Ensure jaw numbers match corresponding groove numbers when changing jaws
- Apply anti-rust oil and return to packaging box for long-term storage
- Prevent dust from entering the three grooves in the measuring head
- Recommended digital indicator range: above 12.7mm/0.5"
