Starrett 00032 Dial Bore Gage 5 to 8 in 6 in Depth

Product Description

The STARRETT 00032 is a dial bore gage designed for accurate internal diameter measurement of bores and holes ranging from 5 to 8 inches. It features a 6-inch probe depth and a graduation of 0.0005 inches, making it suitable for precision inspection work in machine shops, manufacturing facilities, and field service environments. The three-point contact design self-centers in the bore without requiring manual alignment, and the hardened tool steel construction holds up under repeated use. Licensed machinists, maintenance technicians, and metrology professionals use this gage for bore sizing, roundness checks, and quality control verification.

The STARRETT 00032 is suited for inspecting large-diameter bores in industrial and manufacturing settings. Its three-point contact geometry and centralizing plungers allow the gage to seat consistently in round or near-round bores without rocking. Typical applications include cylinder bore inspection, housing bore measurement, and in-process dimensional checks on machined components. The included dial indicator provides a direct readout, keeping workflow efficient on the shop floor or at the machine.

Key Features

• Measurement range of 5 to 8 inches covers large-bore applications
• 0.0005-inch graduation supports high-precision inspection requirements
• 6-inch probe depth reaches into deep bores and blind holes
• Three-point contact design self-centers for repeatable readings
• Hardened tool steel construction resists wear during regular production use
• Includes finished wooden storage case to protect the gage between uses

Compatibility

Designed as an OEM-style precision measurement tool for use in any application requiring internal bore diameter measurement between 5 and 8 inches.

Installation Notes

This gage is used by machinists and metrologists and requires no permanent installation. Before use, zero the indicator against a calibrated ring gage or master setting ring at the target diameter. Handle the gage carefully to avoid dropping, which can damage the dial indicator or shift calibration. Store in the included wooden case when not in use to protect contact points and the dial face.
