Description

Angle grinders are handheld power tools that use iron oxide grinding discs, buffing wheels, wire wheels, flap wheels, and other discs to remove, clean, and polish metals.

Personal Protective Equipment

  • Standard shop personal protective equipment (safety glasses, no long hair, no flowing clothes, etc.) are required.
  • A face shield is strongly suggested.
  • Hearing protection is strongly suggested.
  • Work gloves are suggested, though be careful to not entangle them in the grinding disc.

Safe Operation

  • Clamp materials or make sure they are secure before grinding to prevent excessive vibration or part movement.
  • Keep both hands on the grinder, and neither hand on or behind the workpiece.
  • Start grinder before making contact with the material.
  • Hold the grinder on the material with even pressure, and move it slowly back and forth over the surface of the material. Do not apply heavy pressure, or keep the grinder in one place on the material.
  • DO NOT place the grinder on any surface while it is still in motion but not being used for grinding, or use a surface to stop a grinder.
  • Note that the workpiece will likely be very hot immediately after grinding.
  • Keep the grinder safety engaged whenever the tool is not in use, if applicable.
  • Avoid orienting the tool so that debris is flung towards you, others, or into nearby airspace that bystanders pass through. Attempt to orient the tool so that debris is flung towards the ground or the cutting surface if at all possible.

Common Maintenance Operations

  • Inspect all grinding wheels to ensure they are not nicked, excessively worn, or filled with non-ferrous metals.
  • Install new grinding wheels by depressing the wheel lock, trying to move the wheel to make sure the wheel lock is engaged, and then using the appropriate spanner wrench to remove the nut holding the wheel on. Remove the old wheel, install a new one, and retighten the nut.
  • The orientation of the nut matters. One side is marked "This side against 1/4" wheel". The other side should face the disc when using 1/8" cutoff wheels, flap wheels, etc.

Allowable Materials

  • Materials are governed by the type of wheel you are using. Research what materials are allowed on which wheels before starting work.
  • No non-ferrous materials should be ground with iron oxide wheels. Only flapwheels, buffing wheels and the like should be used on non-ferrous metals.
