Mitutoyo 103-915-10 Outside Micrometer Set 6 Pc

Product Description

The MITUTOYO 103-915-10 is a 6-piece mechanical outside micrometer set covering a measurement range of 150 mm to 300 mm with a graduation of 0.01 mm. Each micrometer features a ratchet stop thimble for consistent measuring force and solid carbide measuring faces for long-term wear resistance. The set is finished in baked enamel for durability. Accuracy is rated at 4 micrometers for the 150 mm to 225 mm range and 5 micrometers for the 225 mm to 300 mm range. Licensed metrologists, machinist shops, and quality control technicians rely on this set for precision dimensional inspection work.

This micrometer set is suited for dimensional measurement tasks in manufacturing, tool and die, quality assurance, and metrology lab environments. It covers six size ranges from 150 mm to 300 mm, making it appropriate for measuring medium to large workpieces. The set includes setting standards from 25 mm upward, a certificate of inspection, a key, and a storage box, allowing the user to verify calibration on-site without additional equipment.

Key Features

• 6-piece set covering 150 mm to 300 mm measurement range
• 0.01 mm graduation for fine dimensional readings
• Ratchet stop thimble provides repeatable, controlled measuring force
• Solid carbide measuring faces resist wear over extended use
• Baked enamel finish for corrosion and impact resistance
• Includes certificate of inspection, setting standards, key, and storage box

Compatibility

Designed as a standalone outside micrometer set for general precision measurement applications requiring coverage from 150 mm to 300 mm; compatible with standard micrometer accessories and setting standards conforming to that range.

Installation Notes

Outside micrometers require no installation but should be handled and stored by qualified metrology or machinist personnel following established calibration procedures. Before use, verify each micrometer against its included setting standard and clean the measuring faces with a lint-free cloth. Never apply excessive clamping force; use the ratchet stop to engage the workpiece consistently. Store the set in the provided box away from heat, moisture, and magnetic fields to maintain calibration integrity.
