Bevel protractor with magnifying lens – SA4980

The bevel protractor with magnifying lens is a measuring instrument designed for checking and measuring angles, inclinations and bevels in mechanical applications, workshops and tooling operations. It is a practical solution when it is necessary to verify a direct angle on a component, compare an inclined profile or set an angular reference during machining or assembly.

The presence of the magnifying lens improves scale visibility, helping the operator read the angle more comfortably and accurately. This feature is especially useful during repetitive inspections, bench adjustments and in all situations where the bevel protractor is used multiple times during the same working phase.

The bevel protractor with magnifying lens is supplied with blades of 150, 200 and 300 mm, allowing the instrument to be configured according to the type of inspection to be performed. This makes the instrument highly versatile, because it can adapt both to small components and to larger surfaces or angled references. Shorter blades are useful for confined spaces and smaller parts, while longer blades provide a wider and more stable contact surface when checking larger inclinations or edges.

From an application point of view, the bevel protractor is suitable for checking internal and external angles, bevels, angular shoulders, inclined surfaces, fixtures and dimensional references. It is also useful for layout operations and angular setting during workshop activities and quality inspections.

Compared to fixed-angle gauges, this instrument offers greater versatility because it allows operators to check different angle values using the same instrument, without being limited to preset values. For this reason, it is particularly useful when working on non-standard components, tooling, fixtures and mechanical parts requiring variable angular verification.

In workshops, it is frequently used during setup and adjustment operations when the inclination of a surface or fixture must be checked quickly against the angle specified on the drawing. The possibility of selecting the most suitable blade length makes the instrument more practical and better aligned with the actual geometry of the component.

A particularly useful accessory for the bevel protractor with magnifying lens is the use of angle gauge blocks, which allow the creation of known and repeatable angular references. These are useful both for verification and calibration of the instrument, because they make it possible to compare the displayed angle with a precise angular reference. In practical applications, they are especially valuable when a reliable angular reference is required during periodic inspections or setup operations.

In summary, the bevel protractor with magnifying lens is a versatile angular measuring instrument suitable for checking and transferring angles on components of different sizes, offering improved readability and interchangeable blades for greater application flexibility.
