POWERTEC USA
8" x 1" Bench Grinder Sharpening Wheel (15512)
The Professional Choice for Cool, Precision Sharpening
The POWERTEC 15512 is a premium 8-inch white aluminum oxide grinding wheel, specifically engineered for the high-precision sharpening of High-Speed Steel (HSS) tools. While standard grey wheels can quickly overheat and ruin the temper of your expensive chisels and lathe tools, this white alundum wheel is designed for a cool-cutting action. The 80-grit medium abrasive provides the perfect balance between efficient stock removal and a refined, sharp edge, making it an essential upgrade for any stationary bench or pedestal grinder.
Featuring a vitrified bond, this wheel is designed to "self-sharpen" during use. As the abrasive grains wear down, the bond releases them to expose fresh, sharp facets, ensuring a consistent and balanced grinding surface. With a 1-inch thickness and a standard 5/8" arbor hole, this wheel delivers the stability and precision required for delicate tool geometry and professional deburring tasks.
- HSS Optimization: Specifically formulated for cool cutting on hardened tool steels.
- Fresh Cutting Surface: Vitrified bond ensures the wheel remains sharp and prevents glazing.
- Balanced Performance: Precision manufacturing ensures minimal vibration for surgical sharpening.
- Versatile 80 Grit: Ideal for removing tiny imperfections and establishing a clean, sharp edge.
- Standard Compatibility: Fits most 8-inch bench grinders with a 5/8-inch spindle.
