3M 89623 Ceramic, 75 mm x 1 mm Thick, 60 Grade, 60 Grit 25

3M 3MTM CubitronTM 3 Series Cutting Disc, 75mm Disc Diameter, 1mm Thickness - 7100304121

This cutting disc is a 75mm portable cut-off wheel designed for heavy-duty metal cutting in industrial settings. It uses precision-shaped ceramic grain to achieve fast, cool cutting while extending wheel life, and is supplied in a multi-disc pack for routine workshop use.

Features & Benefits

• Precision-shaped grain reduces cutting temperature and wear
  60 grit offers aggressive metal removal for stainless steel
  Maximum safe speed 11,500 r/min supports high-speed tools
  9.53mm bore ensures stable mounting on compatible spindles

Applications

• Suitable for cutting 304 stainless steel sheet and plate
  Suitable for sectioning 1018 carbon steel components
  Used for weld removal in machine maintenance tasks
  Ideal for fabrication in electrical and mechanical workshops
  Can be used with angle grinders for automated cut processes

What materials will it cut effectively?

It is formulated for metals including 1018 carbon steel and 304 stainless steel, providing effective removal on common ferrous and stainless substrates.

Which tool speeds are appropriate for safe operation?

The wheel is rated to operate up to 11,500 r/min
users should ensure their grinder does not exceed this maximum speed.

How thin is the cutting profile and why does that matter?

The disc has a 1mm thickness giving a fine kerf that reduces material waste and requires less cutting force for thin-metal work.

How does the abrasive type affect performance?

The precision-shaped ceramic grain slices through metal rather than ploughing, which lowers heat generation and extends abrasive life compared with conventional ceramic grains.
