Metal compass set Centrum 83563 with leads and scribing accessory

Centrum metal compass 83563 is a precision drawing and scribing set designed for technical work, school geometry and hobby projects. The metal construction ensures stable leg alignment for accurate circles and arcs on paper and thin materials. The set contains the metal compass body, replaceable pencil leads and a scribing accessory to transfer exact radii and mark points where measurement accuracy matters.

Advantages

The metal frame provides rigidity and repeatable results when drawing circles or transferring measurements. Replaceable leads allow sustained use without degrading line quality, while the included scribing accessory expands functionality to mark non-graphite lines on thin materials. The adjusting mechanism enables fine radius adjustments for improved precision and consistent performance during classroom exercises or technical sketches.

Suitable for

• School geometry lessons and student exercises
• Technical drawing and drafting tasks
• Hobby modelling and craft projects requiring precise circles
• Measuring and marking radii on paper, card and thin sheet materials

Key specifications

• Material: metal compass body with metal legs
• Includes: replaceable pencil leads and a scribing accessory
• Adjustment: fine radius adjustment mechanism for precise settings
• Marking types: graphite marking with leads and scribing on thin materials
• Intended use surfaces: paper, card, thin sheets

How to use

Open the compass to the required radius and tighten the adjustment to lock the setting. Insert a lead into the pencil holder and secure it before drawing. For scribing, replace or fit the scribing accessory in place of the lead and apply light, consistent pressure while rotating the compass around the fixed point. When changing leads, handle the small parts carefully and store spare leads in a protective case if available.

Usage recommendations

Use on a flat, stable surface for best accuracy; avoid excessive force when scribing to prevent bending the legs. Keep replacement leads dry and protected to maintain crisp marking, and periodically check the adjustment screw for proper tension to ensure consistent results.
