Bore Gage บอร์เกจ Mitutoyo รุ่น 511-713-20 (0.01X50-150มิล)

This is a short range application Bore Gauge Set that automatically self-centres via a centring bridge and offers you the following benefits:

• It reduces the influence of heat from the operator's hand by 50% by making the grip hollow structured, thereby retaining high accuracy measurement.
• Interchangeable washers (0.5 mm thick) are supplied as standard accessories, so you can enable setting in small steps.
• Contact points are carbide (>18 mm range), giving you high durability and wear resistance.
