Type 27 Depressed Centre Grinding Wheels

ALWAYS ensure that the correct wheel has been selected and properly mounted by a qualified person in accordance with the Abrasive Wheels Regulations PUWER 1998 (Provision and Use of Work Equipment Regulations) and HS(G)17.

CHECK that the guard has been adjusted to direct sparks and dust away from the operator and that you are wearing the appropriate safety clothing and eye protection.

These wheels are used on portable (hand-held) angle grinders and are available in diameters of 100 to 230mm. Almost all of the advice for Type 41 and Type 42 wheels applies to this type of wheel. In addition:
  1. They should be used at an angle of 30° - 40° to the workpiece.
    Use at an angle of 30 - 40 degrees to the workpiece.
  2. Shallower angles can cause the wheel edge to feather and break up.
  3. If you have to use a wheel at a shallower angle for a short period, dress the edge back to shape by running it briefly at an angle of 60° - 80° until restored.
  4. For efficient metal removal, the grinding edge should be moved in an outward direction, away from the body.
    Move in an outward direction away from the body.
  5. Do not press down too hard with the wheel as this can cause edge chipping and glazing. Remember - let the wheel do the work.
