Mitutoyo 511-201 Dial Bore Gauge for Small Holes
Total measurement range of 10 to 18.5 mmTwo-point contact for detection of geometry problems such as ovality and taperCarbide-tipped contact points for extended wear and improved abrasion resistance Range:10-18.5mm | Resolution:N/A | Measurement accuracy:0.0002" | Part Number:511-201The Mitutoyo 511-201 Dial Bore Gauge for Small Holes has a measurement range of 10 to 18.5 mm. This direct-measuring gauge uses a two-point contact system to detect geometry problems such as ovality and taper, and carbide-tipped contact points offer extended wear and improved abrasion resistance. The outside diameter of the stem is 8 mm. This gauge is for use with Mitutoyo dial indicators (sold separately).Bore gauges measure holes, or bores, in a workpiece. They can measure the interior diameter of a hole at any depth, while internal micrometers can only measure to the depth of their teeth. Bore gauges are typically calibrated with a setting ring and come in two types: simple and direct-measu
