Safety Data Sheet


  • Always inspect the wheel

  • Always handle and store in a careful manner

  • Always check mounting flanges for equal size and minimum diameter of ⅓″ roper flanges

  • Always check machine speed against the established maximum safe operating speed marked on the wheel

  • Always use mounting blotters when supplied with wheels

  • Always make sure work rest is properly adjusted (center of wheel or above - no more than ⅛″ away from wheel)


  • Always use a safety guard covering at least one half of the grinding wheel

  • Always allow newly mounted wheels to run at operating speed with guard in place for at least one minute before grinding

  • Always wear safety glasses or some type of eye protection when grinding

  • Always turn off coolant before stopping wheel to avoid creating an out-of-balance condition


  • Always store wheel in a dry place at a constant temperature

  • Always provide proper racks, bins, or drawers for storing various types of wheels

  • Always store straight and tapered wheel on edge in racks with two-point cradle support and partitions separating wheels

  • Always use flat shelf for storing thin wheels with resin bond laying them flag to prevent warping

  • Always stack cylinder wheels and large straight cup wheels with corrugated paper cushions between flat sides or in same type rack used for large straight wheels

  • Always stack large flaring cups wheels on flat shelf face-to-face and base-to-base

  • Always use bins, boxes, or drawers to store internal wheels, cups, and other small wheels

common sense rules

  • Always use a guard

  • Always wear eye protection

  • Always comply with ANSI B7.1 and OSHA regulations

  • Never exceed maximum safe speed marked on wheel

  • Never use a cracked wheel or one that been dropped or damaged

  • Never force a wheel onto the machine or alter the size of the mounting hole

  • Never jam work into the wheel

  • Never roll abrasive wheels across a surface

  • Never force grinding so that the motor slows noticeably or work gets hot

  • Never store wheels in a damp place or in extreme temperatures

  • Never store wheel directly on edge with only one point touching shelf or without guard to prevent rolling

  • Never handle wheels carelessly - wheels are brittle and break easily - never bump or drop wheels against one another or other objects

  • Never pile heavy objects on top of wheels

  • Never use mounting flanges unless they are ⅓ the diameter of the wheel and are clean, flat, and free of burns

  • Never over-tighten the mounting nut excessively

  • Never grind the side of the wheel (see ANSI safety code B7.1 for exceptions)

  • Never start the machine until the wheel guard is in place

  • Never stand directly in front of a grinding wheel whenever a grinder is started
