What our Experts Think
  • The Dynabrade 52717 Cone or Plug Wheel Grinder is a high-speed industrial straight-line air grinder built for aggressive metal removal, weld cleanup, and surface preparation in tight or recessed areas.
  • Delivers 18,000 RPM max speed with a 1 HP governor-controlled motor, ensuring strong cutting performance while maintaining stable RPM under load.
  • Designed for use with cone or plug wheels up to ~1-1/4" diameter, making it ideal for internal grinding, casting cleanup, and weld seam finishing.
  • Includes a 6-inch-class straight extension shaft design, giving better reach into deep or confined fabrication areas where standard grinders cannot access.
  • Built with rear exhaust, safety-lock throttle, and rugged industrial housing, optimized for continuous-duty use in fabrication shops, steel plants, and shipyards.
  • Uses a 3/8"-24 spindle thread and 90 PSI operating pressure, standard for heavy-duty pneumatic grinding systems.
  • Best suited for professionals who need a fast, aggressive extended-reach grinder for weld blending, deburring, and heavy surface prep in hard-to-access internal spaces, rather than precision finishing or light-duty work.
   
Q&A    

Q: What is the Dynabrade Cone or Plug Wheel Grinder (52717) used for?
A: It is a 1 HP pneumatic straight-line grinder designed for heavy-duty metal removal, weld cleanup, deburring, and surface preparation using cone or plug abrasive wheels.

Q: What materials is it used on?
A: It is commonly used on steel, stainless steel, castings, and welded structures in fabrication and industrial environments.

Q: What are its key specifications?
A: It runs at 18,000 RPM, uses a 3/8"-24 spindle thread, supports up to 1-1/4" cone or plug wheels, and requires high airflow (about 40 SCFM at 90 PSI).

Q: What makes it suitable for industrial work?
A: It has a governor-controlled motor (maintains speed under load), rear exhaust for operator comfort, and a safety-lock throttle for controlled, continuous grinding.

Q: What industries use it most?
A: It is widely used in welding shops, steel fabrication, shipyards, foundries, and heavy maintenance operations.


Maintenance Tips    
  • Lubricate air motor daily with pneumatic tool oil to ensure smooth, long-lasting operation.
  • Use clean, dry compressed air at recommended pressure to prevent internal wear and corrosion.
  • Inspect cone/plug wheels before use and replace any cracked, worn, or unbalanced abrasives.
  • Keep air inlet and exhaust ports clear of dust and grinding debris for proper airflow.
  • Check spindle, collet, and wheel mounting for tightness and alignment before operation.
  • Ensure hoses and fittings are leak-free to maintain consistent RPM and grinding power.
  • Do not exceed rated wheel speed to prevent safety hazards and premature tool damage.
  • Monitor vibration during use; excessive vibration may indicate imbalance or worn bearings.
  • Clean tool housing after each use to remove metal dust and contaminants.
  • Store in a dry, clean environment to protect internal components from moisture and corrosion.
