10-12mm Pistol-Grip 3 Point Bore Gauge Tool with Digital Indicator for Fast Batch Measurement
This pistol-grip three-point bore gauge enables one-handed operation, making it ideal for measuring in tight spaces and hard-to-reach locations. Designed for fast batch measurements, it allows quick comparison of multiple hole dimensions to verify consistency.
The three-point contact design ensures superior accuracy and stability when measuring both blind and through holes. This configuration effectively minimizes measurement errors, delivering highly precise results.
Available in a comprehensive measuring range from 6-8mm up to 275-300mm (metric) and 0.275-0.35" up to 11-12" (imperial).
Key Features
- Self-centering 3-point mechanism for accurate bore measurement
- Capable of measuring 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
- Comes in a fitted protective case

Applications
This pistol-grip three-point internal micrometer is primarily used for measuring holes, slotted holes, and similar features. It finds extensive application across machinery manufacturing, automotive production, aerospace, electronic components, and various industrial sectors. Its high measurement accuracy, user-friendly design, and simple operation make it an essential tool for precise bore diameter measurement.
Operation 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 return to packaging box for long-term storage
- Prevent dust accumulation in the three grooves of the measuring head
- Recommended digital indicator range: above 12.7mm/0.5"
