Cylinder Bore Gauge Periscope Style 2.6 to 7" Range - Central Tools

The Central Tools 6462 Cylinder Bore Gauge is a professional-grade precision instrument designed for accurate and repeatable measurement of engine cylinder bores and other internal diameters. Engineered for engine builders, machinists, and diagnostic technicians, its unique periscope viewing head ensures clear readouts even in deep or obstructed applications, supporting critical assessments of taper, out-of-round, and wear patterns across a 2.6-inch to 7-inch range.

Key Features

• Periscope Viewing Head: Offers exceptional visibility for easy, accurate readings in deep or obstructed bores, reducing operator strain.
• Wide Measurement Range: Accommodates most automotive gasoline engines, including small-block and big-block V8s, many import engines, and light to medium-duty diesel applications with a 2.6" to 7" (66mm-175mm) capacity.
• Precision Measurement System: Delivers consistent, repeatable results with .001" graduations for accurately checking taper, out-of-round conditions, and wear patterns.
• Robust Construction: Built by Central Tools for daily, professional use in demanding environments such as engine shops, machine shops, and fleet maintenance facilities.
• Ergonomic Design: Promotes proper alignment within the bore, minimizing operator error during critical piston-to-bore clearance and other close-tolerance checks.

Applications

The Central Tools 6462 bore gauge is indispensable for engine teardown, machining, and final assembly tasks where precise cylinder sizing is paramount. It is commonly used to verify piston-to-bore clearance, identify wear and out-of-round conditions prior to honing, and confirm final bore dimensions after machining. Its versatility extends to domestic and import gasoline engines, small-block and big-block V8 rebuilds, and numerous light diesel engines within its specified capacity. Beyond automotive uses, the gauge is also suitable for industrial inspections of sleeves, hydraulic cylinders, and other precision bores as part of quality control or repair procedures.
