The Parduc® Diamond Spinner 100/75 is a precision diamond spinner designed for elliptical skate sharpening profiles where maximum stability is required. It is an excellent choice for professional ice hockey skate sharpening and for sharpeners looking for a stable, long-glide skating profile. The 100/75 combination creates a specialized elliptical grinding wheel profile, helping achieve a consistent and repeatable skate blade shape during sharpening. Like other Parduc® diamond spinners, it is designed for precise grinding wheel dressing for skate sharpening. The spinner is an original Parduc® part for Parduc skate sharpening machines and can also be used as an aftermarket spinner for Blackstone skate sharpeners. It is manufactured with industrial-grade diamond for accurate and durable grinding wheel shaping.
Technical specifications
The correct diamond spinner helps maintain the grinding wheel and ensures consistent skate sharpening results.
Diamond spinners for professional skate sharpening
A diamond spinner is used to dress and shape the grinding wheel of a skate sharpening machine. The spinner profile is transferred to the grinding wheel, allowing the sharpener to create the required Radius of Hollow (RoH) or a specialized combination profile.
Regular wheel dressing keeps the grinding wheel accurate and exposes fresh abrasive material for consistent sharpening. Parduc® diamond spinners are available in a wide range of radii, flat profiles and combination profiles for ice hockey skate sharpening and figure skate sharpening.
The R-value determines the radius of the hollow: smaller radii create a deeper groove with more bite, while larger radii create a shallower groove with more glide. Available profiles: 80, 85, 88, 90, 92, 95 and 100, each in three versions: /50, /75 and /1 are designed for specialized sharpening requirements. The first number represents the width, while the second number represents the depth of hollow.
