This item is a necessary accessory for Master series DIY engraving machine. It is a professional laser head with high speed and high stability.

Recommend to use the CNC model (NC.file/G-code file) to cut.

Main applications: Cutting, Paper cutting, Wood cutting(<5mm), Depth Engraving(<3mm), G-code drawing, Drawing depth engraving, etc. (Especially good at cutting, It can cut wood (3-8mm). It supports metal engraving including alumina oxide, and other non-reflective materials, depth of engraving (0.5-3mm wood). Supported engraving materials: Wood, gray paper, leather, bamboo, blackening plastics, rubber, alumina oxide, etc.
Can not work on the stainless steel, alloy, glass, and some reflective materials.

Note: It is not possible to directly engrave the metal with strong mirror reflectivity, which may cause injury to the operator or burn the laser. Master series engraving machine comes standard with 12V2A charger. If you want to use 20W laser head, you need to prepare another 12V3A power supply.(except Master 20W engraving machine)
