Fowler 52-440-612-0 Bevel Protractor 6 and 12 Inch

Product Description

The FOWLER 52-440-612-0 is a dial-type bevel protractor designed for precise angle measurement in machining, fabrication, and layout work. It reads a full 360 degrees with a dial graduation of 0-90-0 and delivers accuracy to 5 minutes of arc. The satin chrome finish reduces glare during use. The kit includes both a 6-inch and a 12-inch blade, giving technicians flexibility for short and long reference surfaces. A fine-adjustment mechanism allows exact angular positioning without overshoot, and an integrated magnifying glass makes reading the dial quick and reliable. Machinists, tool-and-die makers, and precision fabricators are the primary users.

This bevel protractor suits bench and floor-level layout tasks in machine shops, fabrication facilities, and inspection stations. The two included blade lengths cover a wide range of workpiece sizes, from small components measured with the 6-inch blade to longer stock and structural sections measured with the 12-inch blade. The 0-90-0 dial reading format is standard for angular inspection workflows and is compatible with common shop documentation practices.

Key Features

• Dual blade set: 6-inch and 12-inch blades included
• Full 360-degree measurement range with 0-90-0 dial reading
• Accuracy to 5 minutes of arc
• Fine-adjustment mechanism for precise angular setting without overshoot

Compatibility

Designed as a general-purpose dial bevel protractor for use with standard machining, layout, and inspection setups where blade-style protractors are specified.

Installation Notes

No permanent installation is required. Secure the workpiece before taking measurements to prevent movement that could affect reading accuracy. Clean contact surfaces on both the blade and the base stock before use to ensure full blade seating. Store blades and the protractor body in the provided case when not in use to protect calibration.
