Blake 2814124 0.0005in Dial Bore Gauge Set with Wooden Case

The Blake 2814124 is a new dial bore gauge (also known as a dial bore indicator or internal measuring gauge) stored in a fitted hardwood case with brass latch hardware, including the primary gauge head, an extension rod, a bent contact point accessory, and instructional documentation. The dial face is clearly marked with graduations reading 0–5–10–15–20–25–30–35–40, with the face legend indicating 0.0005" graduation (resolution), and the dial is labeled "OFFSET" type — a Blake-style offset bore gauge design used to measure internal diameters by referencing off a known bore size. The gauge features a black anodized cylindrical body with a chrome bezel and white dial face; the included long black extension rod extends the usable measuring depth, and the bent contact arm accessory allows measurement in restricted-access bores. Blake offset-style bore gauges are used primarily in precision machining environments — including jig boring, milling, and grinding operations — to center a workpiece bore over a spindle or to compare an internal diameter against a master ring gauge setting.
