Mitutoyo 187-104 Acute Angle Attachment 360 Degrees

Product Description

The MITUTOYO 187-104 is an acute angle attachment designed for use with compatible Mitutoyo protractor systems. This precision accessory extends the measurement capability of a vernier bevel protractor, allowing technicians and machinists to measure acute angles that fall outside the standard range of the base instrument. The attachment provides a maximum measurement range of 360 degrees and is built to the tight tolerances Mitutoyo is known for in precision metrology tooling. It is commonly used in machine shops, tool rooms, and fabrication environments where accurate angular measurement is required.

This attachment is suited for professional metrology applications in industrial and manufacturing settings. Machinists, quality control inspectors, toolmakers, and precision fabricators rely on angle attachments like the 187-104 to verify part geometry, check chamfers, and confirm angular tolerances on machined components. It is intended for bench use and pairs with a vernier bevel protractor to extend measurement versatility.

Key Features

• 360-degree maximum measurement range for full angular coverage
• Acute angle measurement capability extends standard protractor function
• Designed to Mitutoyo precision metrology standards
• Compact attachment format for bench and field inspection use
• Sold individually, one attachment per package

Compatibility

Designed as an OEM-style acute angle attachment for compatible Mitutoyo vernier bevel protractor instruments. Refer to the Mitutoyo product documentation to confirm fitment with your specific protractor model before installation.

Installation Notes

Installation of this attachment should be performed by a qualified machinist or metrology technician familiar with precision measurement instruments. Ensure the base protractor is clean and free of debris before attaching the blade to maintain measurement accuracy. Handle with care to avoid dropping or impacting the blade, as damage to the contact surfaces will affect angular accuracy. Follow Mitutoyo instrument documentation for proper attachment procedure.
