FAQs
Can I use this disc on hardened steel?
While it can cut through some hardened materials, it is primarily optimized for ceramics, glass, and softer stone. Expect faster wear if used exclusively on metal.
Do I need to use water as a coolant?
Using a light water spray can help suppress dust and extend the life of the diamond coating, but ensure your rotary tool is shielded from moisture.
What is the recommended RPM range?
Refer to your rotary tool manual for the diameter of the disc, but generally, diamond discs perform best at high speeds with light, consistent pressure.
Is the disc compatible with non-Proxxon tools?
Yes, provided your tool accepts standard 2.35mm or 3.0mm mandrels, though best results are achieved with Proxxon precision equipment.
How do I know when the disc needs replacing?
The disc should be replaced if you observe visible cracks, if the diamond coating has worn away exposing the base core, or if it no longer cuts effectively even after dressing.
Troubleshooting
The disc is cutting slowly or glazing over
The edge may be loaded with debris. Use a dressing stone to gently clear the diamond particles.
Excessive vibration during operation
Check that the mandrel is securely fastened and that the disc is perfectly centered on the arbor.
Disc is chipping the material
Reduce feed pressure and ensure the tool is operating at the recommended RPM for the specific material density.
Pros and Cons
Pros
- Excellent precision for intricate detailing
- High-speed cutting capability with turbo rim
- Long service life compared to standard cutting discs
- Superior finish on glass and ceramic materials
Cons
- Requires careful alignment to prevent shattering
- Produces significant dust requiring proper ventilation
- Not suitable for heavy-duty metal fabrication
Setup, Compatibility & Care
To install the disc, ensure your rotary tool is powered down and the collet is clean. Secure the disc using an appropriate mandrel, ensuring it is centered to prevent wobbling, which can cause cracking.
Compatibility: The 28157 is designed for use with Proxxon rotary tools and standard hobby rotary tools that accept small diameter cutting discs.
Care Instructions: Always store the disc in a dry, cool environment. If the cutting effectiveness decreases, it is often due to loaded debris; clean the edge gently with a soft abrasive stone to expose fresh diamond grit. Never use the disc if it shows visible cracks or deformities.
