Straight grinders hold a grinding wheel in line with the motor, so they reach into pipes, molds, castings and inside corners. Foundries, fabricators and machine shops use them for heavy grinding and finishing where an angle grinder will not fit.

How to choose a straight grinder

  • Wheel size: 5" (125mm) wheels are common. 6" models remove more material, while 3" air grinders reach tight spots.
  • Power: 550W to 750W handles general grinding. 1000W to 1100W models keep speed under heavy load.
  • Electric or pneumatic: electric models plug in anywhere. Toku and S-Ks pneumatic straight grinders are light and suit shops with compressors.
  • Wheel: use the correct wheel size and speed rating, and replace worn wheels.
