Frequently Asked Questions
What are EVE Diapol HP polishers used for?
They are diamond polishers for porcelain and feldspathic ceramic restorations, used to bring the surface back to a high-luster shine after grinding and contouring.
What does HP shank mean?
HP is the long, straight shank used in lab handpieces and micromotors, for bench and extraoral work rather than a chairside contra-angle.
Which shapes and sizes are available?
Per the product chart: large wheel RDHP26 (26 x 2 mm), wheel RDHP17 (17 x 2.5 mm) and point RDHP2 (4 x 13 mm), each in coarse, medium and fine.
What is the correct grit sequence?
Coarse first to remove the grinding marks, then medium to refine, then fine for the final shine. Each step removes the scratch pattern of the one before it.
How do I tell the grits apart?
By color: blue is coarse, pink is medium and gray is fine. The last letter of the catalog number (C, M or F) also shows the grit.
What speed should I run them at?
Use a moderate, controlled speed rather than the maximum of your handpiece. Too much speed builds heat and can glaze over the diamond content.
Do I still need to glaze the restoration?
A full polishing sequence can bring porcelain to a high shine without another glaze firing. Some labs still glaze depending on the case.
Which shape should I use first?
Use the 26 mm large wheel for broad surfaces and bridges, the 17 mm wheel for single crowns, and the point for occlusal anatomy and areas a wheel cannot reach.
Can I use them on lithium disilicate or zirconia?
They are made for porcelain and feldspathic ceramic. For lithium disilicate (E.max), the EVE Diapro HP polishers are the dedicated choice, and zirconia is best handled with a zirconia polisher.
How do I know when to replace a polisher?
When it takes noticeably longer to bring up the same shine, it is time to replace it. Light pressure and constant movement help it last longer.
