In the world of ice hockey and figure skating, the difference between a good performance and a great one can be measured in millimeters. The perfect edge on a skate blade-delivering explosive acceleration, vice-like grip in turns, and effortless glide-isn’t just the result of a good sharpening machine. The process begins one step before: with a perfectly shaped grinding wheel.
That’s where the Parduc® diamond spinner comes in. As the essential tool for shaping your grinding wheel, the spinner is the true source of precision, ensuring every skate you sharpen has the exact radius and flawless finish your customers and players demand.
A diamond spinner is a high-quality dressing tool designed to shape skate sharpening grinding wheels into the correct radius or flat profile. Think of it as the master key for your skate sharpener. Whether sharpening ice hockey skates or figure skates, the spinner ensures your wheel is dressed to the exact specification—so every sharpening is accurate, consistent, and professional.
This process is critical for two reasons:
- Creates the profile: The shape of the spinner is directly transferred to the grinding wheel, which then grinds that exact shape into the skate blade. Without a precision spinner, achieving a consistent Radius of Hollow (RoH) is impossible.
- Maintains the wheel: Over time, grinding wheels wear down and can become uneven. Using a diamond spinner regularly “dresses” the wheel, truing its surface and exposing fresh abrasive for a clean, consistent cut every time.
Parduc® uses industrial-grade diamonds because they are the hardest material available, guaranteeing an incredibly precise, clean, and durable shaping tool that will last through countless sharpenings.
When you choose a Parduc® Diamond Spinner, you’re investing in quality and performance that pays off with every pair of skates you sharpen.
✅ Professional accuracy – Dress your grinding wheel to the exact radius needed.
✅ Durability – Manufactured with industrial-grade diamond for long-lasting use.
✅ Versatility – Suitable for both Parduc® skate sharpeners and as an aftermarket spinner for Blackstone machines (note: not an original Blackstone part).
✅ Multiple options – Available in a wide range of radii and flat profiles.
✅ Trusted quality – Original Parduc® part, designed for professional sharpeners worldwide.
Choosing the right spinner means choosing the right edge. The R-value corresponds to the Radius of Hollow (RoH); a smaller number creates a deeper groove for more bite, while a larger number creates a shallower groove for better glide. The ##/## values are designed for creating specialized compound hollows, such as the popular Flat Bottom sharpening, giving you even greater control over the balance of grip and glide.
