No name Kątownik 150/100 Mksc KL.1 (0370104) — 150×100 mm angle square, class 1

No name Kątownik 150/100 Mksc KL.1 is a precision angle square with nominal leg lengths of 150 mm and 100 mm designed for accurate checking and marking of right angles. Manufactured for workshop and shop environments, this Class 1 instrument provides defined geometric references for inspection, layout and machining tasks in metalworking and woodworking. The tool is built to meet the dimensional and accuracy requirements of its accuracy class for consistent repeatability during routine measurement and marking operations.

Advantages

The angle square offers a hardened and stable reference surface that resists wear and preserves accuracy over time. Its two nominal leg lengths give flexibility for a range of component sizes, while the Class 1 accuracy ensures tight angular tolerance suitable for demanding layout and inspection work. The compact form factor and clear right-angle geometry make it suitable for bench use and handheld checking on workpieces.

Suitable for

• Checking 90° angles on machined parts and assemblies
• Marking reference lines for cutting and drilling operations
• Dimensional inspection in metalworking and woodworking shops
• Setup and alignment of fixtures, jigs and small assemblies

Key specifications

• Nominal leg lengths: 150 mm and 100 mm
• Accuracy class: Class 1 (high precision for workshop use)
• Intended application: right-angle checking, marking and inspection
• Construction: rigid right-angle body with defined bearing surfaces
• Typical environments: metalworking and woodworking shops, inspection benches

How to use

Place the longer or shorter leg of the angle square firmly against the reference edge of the workpiece so that the bearing surfaces make full contact. Use the opposite leg as a guide to mark a right-angle line with a scribe or pencil. For inspection, align the tool with the feature to be checked and observe any gap or deviation; use feeler gauges or a dial indicator if numerical tolerance measurement is required. Handle the instrument by its body and avoid applying torque that could deform the bearing surfaces.

Usage recommendations

Store the angle square in a protective case or on a clean, flat surface to prevent knocks and contamination. Clean bearing surfaces before use and avoid using the tool for prying or as a striking surface. Periodically verify accuracy against a certified reference or master square if used for critical inspection tasks.
