Starrett 67119 Mechanical Depth Micrometer 12 Inch Range

Product Description

The STARRETT 67119 is a mechanical depth micrometer designed for precise depth measurement in machining, fabrication, and tool-and-die applications. It delivers a 12-inch maximum measurement range using a set of 12 interchangeable rods, each 0.1563 inches in diameter. The instrument reads to a 0.001-inch graduation with an accuracy of 0.0001 to 0.0002 inches, making it well suited for inspecting bores, steps, slots, and counterbores where tight tolerances matter. A satin chrome finish reduces glare under shop lighting and resists corrosion from handling. Licensed machinists, toolmakers, and precision mechanics are the primary users of this instrument.

This depth micrometer is used in precision manufacturing environments including machine shops, tool rooms, and quality control stations. The 6-inch base length provides stable contact across wider workpiece surfaces, reducing tipping and improving reading consistency. It is appropriate for both production-floor measurement tasks and bench inspection work wherever a 12-inch depth range is required. The included case keeps all 12 rods organized and protected between uses.

Key Features

• 12-inch maximum measurement range with 12 interchangeable rods included
• 0.001-inch graduation for fine, repeatable readings
• Accuracy of 0.0001 to 0.0002 inches
• Ratchet stop thimble ensures consistent measuring pressure
• Ring-type knurled lock nut for quick and secure spindle locking
• 6-inch base length for stable contact on wider surfaces
• Satin chrome finish minimizes glare and resists corrosion

Compatibility

Designed as a standard mechanical depth micrometer suitable for general precision measurement tasks in machine shops, tool rooms, and inspection environments requiring up to 12 inches of depth range.

Installation Notes

Depth micrometers are handled and used by machinists and quality technicians rather than installed in a system. Before use, verify the correct rod is seated and locked, and zero the instrument on a known flat reference surface. Store rods in the provided case to prevent damage to measuring surfaces. Calibrate the instrument periodically against certified gauge blocks in accordance with your facility metrology procedures.
