Angle Gauge Helios Preisser Kątownik 150/100 MKSC 45 model 0395103, 45° measuring square 150x100 mm

Helios Preisser Kątownik 150/100 MKSC 45 is a precision 45° angle gauge and measuring square with nominal blade dimensions 150 x 100 mm. Designed for accurate angle checks and layout work, this measuring square provides a stable reference for marking, aligning and verifying 45° angles in metalworking, woodworking and inspection tasks. The compact size makes it suitable for bench work and on-site measurements where space is limited, while the rigid construction keeps the angle true during repetitive use.

Advantages

The instrument offers a reliably machined 45° angle and clearly defined edges for precise marking and scribing. Its nominal dimensions give predictable coverage for common layout needs without obstructing visibility, and the durable build resists deformation in normal workshop conditions. The simple geometry and light weight allow quick positioning and handling, reducing setup time for routine checks and production processes.

Suitable for

• Checking and marking 45° mitres in woodworking
• Setting and verifying angles on metal parts during fabrication
• Inspection and quality control tasks requiring a fixed 45° reference
• Layout work on jigs, fixtures and small assemblies

Key specifications

• Angle: 45°
• Blade dimensions (nominal): 150 x 100 mm
• Material: hardened and machined metal construction for stability
• Edge style: defined straight edges for scribing and marking
• Weight: lightweight for handheld positioning

How to use

Place the square against the workpiece so the inside face rests flush along the reference edge, ensuring the 45° blade bears evenly on the surface to be marked or checked. Use a scribe or pencil along the appropriate edge to transfer the angle, or align cutting guides and stops against the square for setup. For inspection, hold the gauge firmly in position and visually confirm that the mating edge or bevel aligns with the square’s faces; use feeler gauges where fine clearance measurement is required. Store the gauge flat or suspended to avoid bending or edge damage.

Usage recommendations

Keep the edges clean and free of burrs to maintain accuracy; avoid exposing the tool to corrosive environments and handle with care to prevent knocks that could disturb the machined angle. For best results, re-check critical angles periodically with a calibrated reference standard.
