Starrett 68071 Outside Micrometer Set 4 Piece

Product Description

The STARRETT 68071 is a 4-piece mechanical outside micrometer set designed for precision dimensional measurement across a range of 0 to 100 mm in 25 mm increments. Each micrometer features a ratchet stop thimble for consistent measuring force and solid carbide measuring faces for long-term wear resistance. The satin chrome finish reduces glare in shop lighting. This set is used by machinists, metrology technicians, and quality-control professionals who require reliable, repeatable measurements on metal, plastic, and composite workpieces. Graduation is 0.01 mm throughout the set.

The set covers four measurement ranges: 0 to 25 mm, 25 to 50 mm, 50 to 75 mm, and 75 to 100 mm. This makes it suitable for general-purpose inspection work in job shops, manufacturing facilities, and tool rooms where parts fall within the 0 to 100 mm outside-diameter range. The included case keeps all four micrometers organized and protected between uses. Standards of 25 mm, 50 mm, and 75 mm are included for field calibration checks on the larger-range instruments.

Key Features

• Solid carbide measuring faces resist wear during repeated use on hard materials
• Ratchet stop thimble delivers consistent measuring pressure across readings
• Satin chrome finish minimizes glare in bright shop environments
• Four micrometers cover full 0 to 100 mm range in 25 mm steps
• Includes protective case and calibration standards for field verification
• 0.01 mm graduation for fine-tolerance inspection work

Compatibility

Designed as a general-purpose outside micrometer set for measurement tasks requiring coverage from 0 to 100 mm with 0.01 mm graduation. Also cataloged under Starrett number S436.1MBXRLZ.

Installation Notes

Outside micrometers require no installation but should be zeroed and verified against the included calibration standards before use. Store instruments in the provided case to prevent damage to the measuring faces and spindle threads. Clean measuring faces with a lint-free cloth before each use. Calibration and maintenance should be performed by qualified metrology personnel in accordance with applicable shop quality standards.
