18-160mm Bore Gauge Set Series (3 Piece) - 2824 Series (Insize)

The Insize 18-160mm Bore Gauge Set (3 Piece) is a precision instrument designed to measure the inside diameter of holes, cylinders, or pipes. This 3‑piece kit covers a broad 18–160 mm range and is suitable for engineers, machinists, technicians, and hobbyists who need fast, repeatable bore measurements across common sizes.

Measurement uses a dial indicator (not included for the 35–50 mm and 50–160 mm ranges). The gauge features ceramic and steel measuring faces for durability and repeatable results. Not suitable for 0.001 mm dial indicators. The set is stored in a protective case with foam inserts to keep every piece secure during storage or transport.

• Durable ceramic/steel contact points: Ceramic and steel measuring faces resist wear, enabling repeated, reliable measurements over time.
• High precision with repeatable results: Repeatability to 0.003 mm and accuracy of ±0.018 mm deliver consistent bore measurements.
• Wide measuring range with flexible accessories: Measuring range up to 160 mm, with optional accessories including a setting ring (6312) and a long handle (7351) to expand versatility.

This bore gauge set helps you quickly verify bore diameters during setup, inspection, and maintenance, reducing rework and ensuring consistent fits across parts. The combination of wear‑resistant contact points, a broad size range, and secure case storage supports reliable performance in busy workshops and on-site checks, giving you confidence in every measurement.
