Magnum 11 Piece SAE Precision Dial Bore Gauge Measurement Set (1025)

Finding taper and out-of-round in deep engine cylinders is impossible without the right internal measurement tools. The Magnum 1025 11-Piece SAE Precision Dial Bore Gauge Measurement Set allows engine builders to map bore dimensions quickly and accurately. The dial indicator provides a clear visual reading of internal variations, eliminating the guesswork of snap gauges and helping ensure perfect piston ring sealing.

Features

• Precision dial indicator - shows exact dimensional variations at a glance.
• Interchangeable anvils - cover a wide range of bore sizes without needing multiple tools.
• Insulated grip - prevents hand heat from expanding the shaft and altering readings.

Common Shop Applications

• Mapping engine block cylinders for taper.
• Measuring bearing housing bores.

Frequently Asked Questions

• How do I calibrate the dial to my bore size? - Lock an outside micrometer to the target bore size, insert the bore gauge tip, and turn the dial bezel to zero.
• Will this measure small engine cylinders? - Check your specific bore range; the interchangeable anvils cover most standard automotive and light truck cylinders.
