Quick and Easy Operation 50-63mm Three Point Pistol Grip Bore Micrometers for Fast Batch Measurement
The pistol-grip three-point micrometer enables one-handed operation, making it ideal for measuring in tight spaces or hard-to-reach locations. This design is particularly suitable for batch measurements, allowing for rapid comparison of multiple hole dimensions to verify consistency.
With three contact points, this micrometer provides superior accuracy and stability when measuring both blind and through holes. The three-point contact design effectively minimizes measurement errors, ensuring precise and reliable results.
Available with an extensive measuring range from 6-8mm up to 275-300mm for metric measurements, and 0.275-0.35″ up to 11-12″ for imperial measurements.
Key Features
- Self-centering 3-point design for accurate bore measurement
- Measurement capability 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
The pistol-grip three-point internal micrometer is primarily used for measuring holes and slotted holes. It is widely employed across various industrial sectors including machinery manufacturing, automobile manufacturing, aerospace, and electronic components. With its high measurement accuracy, user-friendly design, and simple operation, it has become an essential tool for precise bore diameter measurement.
Operation & Maintenance 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 correspond with the three grooves in the measuring head
- Apply anti-rust oil and store in packaging box when not in use for extended periods
- Prevent dust from entering the three grooves in the measuring head
- For optimal performance with pistol-grip three-point internal micrometers, use digital indicators with range above 12.7mm/0.5''
