## Summary description

xTool K9 glass block, dimensions 50×50×80 mm, is an optical-grade glass block intended for precision engraving, laser calibration, alignment and display use.

## Long description

The xTool K9 glass block (50 × 50 × 80 mm) is an optical-grade rectangular solid designed for precision engraving, laser calibration, alignment and display. Its flat faces and high transparency make it suitable for inspecting engraving results, mounting as a stable workpiece or using in optical demonstrations where consistent clarity and dimensional stability are required.
Advantages
The K9 optical glass offers high transparency and stable geometry, enabling clear, detailed internal and surface engravings. It is compatible with UV laser processing modes such as surface engraving, embossing and internal engraving, providing versatility for testing, prototyping and finished decorative pieces. Its compact size and uniform surfaces simplify handling and positioning during engraving and measurement tasks.
Suitable for
Precision UV laser engraving and internal 3D engraving tests
Calibrating and aligning xTool F2 Ultra UV laser systems
Prototyping and quality inspection of engraving settings
Small decorative displays, awards or personalized gifts
When it may not be suitable
This glass block is not intended for structural or load-bearing applications and should not be used where mechanical strength or impact resistance is required. It may be unsuitable for very large-scale production tasks because of its small, fixed dimensions; for high-volume production, larger or different-format materials may be more practical.
Key specifications

How to use

What to consider before purchase
Confirm compatibility with your UV laser system, specifically xTool F2 Ultra for full-featured support
Assess whether the 50×50×80 mm size fits your project requirements and fixtures
Consider the handling and storage needs of optical glass to avoid scratches and contamination
Usage recommendations
For reliable engraving results, clean the block with a lint-free cloth and isopropyl alcohol, verify laser focus and power on a test area, and secure the block to prevent movement during processing.
