Mitutoyo 187-904-10 Bevel Protractor 6 Inch Blade

Product Description

The MITUTOYO 187-904-10 is a dial-style bevel protractor designed for precise angular measurement in professional layout, inspection, and machining applications. The instrument features a 6-inch blade and a round dial head that reads from -360 to 360 degrees with a blade graduation of 0.01 mm. The body is constructed from steel for durability and dimensional stability on the shop floor or inspection bench. A screw mount secures the blade at the selected angle, locking the reading in place for transfer or verification work. This tool is intended for use by machinists, tool and die makers, quality control technicians, and precision tradespeople.

This protractor is suited for angular layout and inspection tasks in manufacturing, fabrication, and metrology environments. It performs well in setups where consistent, repeatable angle measurement is required across multiple workpieces. The dial readout eliminates the need for a vernier scale, making it readable quickly under production conditions. Typical applications include checking bevel angles on cut stock, setting machine tool fixtures, and verifying angular tolerances on finished parts.

Key Features

• Dial-style readout for fast, direct angle reading without a vernier scale
• 6-inch blade length for extended reach on larger workpieces
• Measurement range of -360 to 360 degrees covers full rotational layout tasks
• Blade graduation of 0.01 mm for fine incremental positioning
• Steel construction provides durability and resistance to shop-floor wear
• Screw mount locks blade securely at the selected angle

Compatibility

Designed as an OEM-style bevel protractor for professional metrology and precision layout applications requiring a dial-type instrument with a 6-inch blade.

Installation Notes

Bevel protractors do not require installation in the traditional sense but should be handled and stored in accordance with standard metrology practices. Before use, verify the dial zero against a known reference surface. Keep the blade and pivot mechanism clean and free of chips or coolant to maintain measurement accuracy. Calibration should be performed at regular intervals per your facility quality management procedures.
