Specification

Description

Vitrified bond aluminum oxide bench and pedestal grinding wheels are a cornerstone of general toolroom operations, offering a balanced combination of cutting efficiency, dimensional stability, and predictable wear. Designed for sharpening, deburring, and light stock removal on ferrous materials, these wheels provide steady grinding action and excellent form retention across a wide range of tasks. The vitrified bond structure ensures rigidity and thermal stability, allowing the wheel to maintain shape and cutting behavior over long service intervals. Whether used for maintaining cutting tools, cleaning up welds, or preparing parts for machining, these wheels deliver dependable performance that supports accuracy, productivity, and repeatable results in toolrooms, maintenance departments, and fabrication shops.

Features

  • Aluminum Oxide Abrasive Grain—Tough, blocky aluminum oxide grains provide reliable cutting performance on carbon and alloy steels commonly found in toolroom applications.
  • Vitrified Bond System—The rigid, porous vitrified bond offers excellent thermal stability and controlled grain release, supporting consistent cutting and long wheel life.
  • Balanced Wheel Structure—Engineered for smooth operation on bench and pedestal grinders, reducing vibration and improving operator control.
  • Controlled Porosity—Allows efficient chip clearance and coolant or airflow access, helping to manage heat and prevent loading.
  • Wide Range of Grits and Grades—Available in coarse to fine grits and multiple hardness levels to suit sharpening, deburring, and light grinding needs.

Application

Application

  • 1

    Sharpening drills, chisels, punches, and general cutting tools.

  • 2

    Deburring and edge conditioning of machined steel components.

  • 3

    Light stock removal and surface cleanup on mild and alloy steels.

Recommendations

  • Select the appropriate grit and grade based on the operation—coarser grits for stock removal, finer grits for sharpening and finishing.
  • Dress the wheel regularly to maintain sharp cutting action and proper wheel geometry.
  • Operate within recommended spindle speeds to ensure safe and efficient grinding.
  • Use light, consistent pressure to avoid overheating tools and to extend wheel life.
  • Ensure proper wheel mounting and balancing to minimize vibration and improve surface finish.
