Protractor NEO tools 72-035 — precision angle measuring tool, weight 1.84 kg, single piece

NEO tools 72-035 is a precision protractor with base designed for accurate angle measurement and reliable straight setting. Entirely made from a single piece of carbon steel, the flat angle surface is specially hardened and polished to deliver consistent readings. The tool follows DIN875/2 dimensions and features two equal-thickness arms — a longer arm of 300 mm and a shorter arm of 200 mm — providing stable contact and high strength for workshop and on-site use. Weighing 1.84 kg and supplied as a single piece, this protractor is built for tasks that require dependable 90° setting and precise marking.

Advantages

The one-piece carbon steel construction ensures durability and reduces the risk of misalignment between arms. A hardened and polished flat angle surface provides exceptional measurement repeatability and wear resistance. Identical arm thicknesses help maintain geometric accuracy, and the DIN875/2 manufacturing standard ensures dimensional reliability. The substantial tool weight and robust material contribute to stable placement during layout, carpentry or metalworking operations.

Suitable for

• Setting and checking 90° angles during assembly and layout
• Carpentry and joinery marking and checking
• Metalworking and fabrication angle measurements
• Precision assembly and machine setup requiring straight setting

Key specifications

• Standard: DIN875/2
• Longer arm length: 300 mm
• Shorter arm length: 200 mm
• Construction: one-piece design
• Flat angle surface: hardened and polished
• Weight: 1.84 kg

How to use

Place the protractor base firmly against the reference surface and align the arms to the workpiece so the flat angle faces the area to be marked or checked. For setting a 90° angle, ensure the arms sit flush against both surfaces and verify contact along the hardened flat. Use the longer or shorter arm as required for reach and stability, then mark or scribe along the edge for layout work. For measurement checks, visually confirm uniform contact and repeatability by repositioning the tool if necessary.

Usage recommendations

Keep the hardened flat surface clean and free of chips or burrs to maintain accuracy. Store the protractor in a dry place to minimize corrosion of the carbon steel. Avoid striking or bending the arms; if heavy impact occurs, re-check angle accuracy before critical use. Use light machine oil on storage to prevent surface oxidation if prolonged storage in humid conditions is expected.
