Specification

Description

These 12A2 resin diamond cup wheels are engineered for the specialized maintenance of saw blades and cutting knives. Their resin bond structure provides a forgiving, free-cutting action that holds form well, ensuring repeatable geometry and durable edge quality, while still providing excellent surface finishes. The diamond abrasive delivers superior hardness and sharpness retention, making these wheels ideal for gumming, sharpening, and clearing operations. With excellent thermal stability and resistance to wear, they maximize productivity in both manual and CNC grinding applications.

Features

  • Resin Bond Technology—Offers flexibility and durability, ensuring the wheel maintains performance over extended use.
  • High-Performance Diamond Grain—Provides unmatched hardness and cutting ability for efficient material removal on carbide and other nonferrous materials.
  • Cup Wheel Geometry—Specialized forms allow for effective access to gullets, edges, and tooth profiles during sharpening and gumming.
  • Cool Grinding Action—Reduces thermal stress and risk of burning, which is critical in edge maintenance of cutting tools.

Application

Application

  • 1

    Gumming and reshaping the gullets of circular saw blades.

  • 2

    Sharpening carbide-tipped saws, planer knives, and chipper blades.

  • 3

    Clearing wear patterns from woodworking and metal-cutting saw teeth to restore performance.

Recommendations

  • Use with proper coolant flow to control heat and extend wheel and tool life.
  • True and Dress wheels with appropriate wheels and sticks to condition the tool for optimal use.
  • Match wheel specifications (grit, hardness, bond) to the specific tool material and application.
  • Operate within recommended speed limits to ensure safety and optimal grinding results.
  • Store wheels in dry, stable conditions to prevent bond damage prior to use.
