Protractor Vorel 18473, 250 mm length, metal/steel angle measuring tool

The Vorel 18473 protractor is a compact angle-measuring tool with a 250 mm movable arm, designed for measuring and transferring angles and drawing straight lines in metalworking, carpentry and general workshop tasks. Constructed primarily from durable ABS plastic with a steel-reinforced arm, the tool combines a clearly marked circular scale with millimetre and inch graduations along the arm and an adjustable vial for level checks. The protractor is supplied as a single unit and is suitable for both checking existing angles and laying out new ones.

Advantages

The Vorel 18473 offers a clear, high‑contrast scale with black markings on a yellow background for improved visibility in varied lighting conditions. Its 250 mm movable arm locks with screws to hold settings securely, while the movable vial can be mounted on the arm to perform quick level checks and aid precise transfers. Graduations every 1° on the circumference and dual metric/imperial markings on the arm make the tool versatile for different measurement systems. The design balances accuracy and simplicity, making it practical for tradespeople and DIY users needing reliable angle layout and straight-edge guidance.

Suitable for

• Measuring and transferring angles on metal and wood
• Layout work in carpentry and joinery
• Checking and setting angles on machine parts and fixtures
• General workshop marking and straight‑edge drawing

Key specifications

• Movable arm length: 250 mm
• Material: durable ABS plastic body with steel/metal arm reinforcement
• Angle scale: circular graduation every 1°
• Arm graduations: millimetre and inch markings on the movable arm
• Visibility: black markings on yellow background for contrast
• Locking: arm locking screws to fix selected angle
• Level check: movable vial that can be mounted on the arm

How to use

Place the protractor’s circular base against the reference edge and loosen the arm locking screws to set the movable arm. Rotate the arm until the desired angle reading on the circumference aligns with the index mark, then tighten the screws to secure the position. Use the millimetre or inch graduations on the arm to mark distances or draw straight lines from the pivot point. Mount the movable vial on the arm when a level indication is required; use it to confirm horizontal or vertical alignment before transferring the angle onto the workpiece.

Usage recommendations

For consistent accuracy, ensure the tool is clean and free of debris before measuring, and tighten the locking screws firmly after adjustment. When working on metal surfaces, support the arm close to the pivot to reduce flex and check readings against a known reference if high precision is required.
