5.1. Powering On and Adjusting Stroke Depth

The Dremel Engraver features an on/off switch and a variable stroke control dial to adjust the engraving depth.

• Plug the engraver into a 120-Volt AC power outlet.
• Turn the tool on using the switch located at the rear of the tool.
• Adjust the variable stroke dial (numbered 1 to 5) to control the engraving depth. A lower number provides a finer line, while a higher number creates a deeper groove. Experiment on scrap material to find the desired setting.

5.2. Engraving Techniques

For best results, hold the engraver like a pencil and apply light, consistent pressure. Allow the tool to do the work; excessive force is not necessary and can lead to less precise results.

Using the Stencil Template

The included letter/number stencil template can help create uniform and neat engravings.

• Secure the stencil to your workpiece using tape or a clamp to prevent it from shifting.
• Trace the desired letters or numbers with the engraver, keeping the tip within the stencil's cutouts.
• For deeper engravings, make multiple passes over the same area.

Engraving Different Materials

The Dremel Engraver is suitable for a wide range of materials:

• โลหะ: Use a medium to deep stroke setting. Practice on scrap metal first.
• Glass & Ceramic: Use a lighter stroke setting to avoid cracking. Work slowly and steadily.
• Wood & Leather: Adjust the stroke depth based on the desired effect, from light scoring to deep carving.
• พลาสติก: Typically requires a lighter stroke setting to prevent melting or excessive material removal.
