3M Cubitron 3 SA90007 T27 125 mm 36+ Grit Grinding Wheel

The 3M Cubitron 3 depressed center grinding wheel is designed for aggressive weld grinding and heavy material removal on steel, stainless steel and ferrous metals. Type T27, 125 mm x 6 mm x 22.23 mm (5 in x 1/4 in x 7/8 in), 36+ grit. Sold in a package of 10 units. Compliant with ANSI B7.1. Note: available on special order.

3M purchase code: 7100303967, model: AB03967 / 90007

Cubitron 3 technology uses precision-shaped triangular ceramic grains that fracture in a controlled manner during use, continuously exposing new sharp cutting edges. Result: cutting up to 2 times faster, less heat generated and longer service life than conventional wheels. The T27 design allows flat and angle grinding on weld surfaces.

Advantages

• Weld grinding: 36+ grit Cubitron 3 removes weld beads, excess metal and oxides quickly and in a controlled manner. T27 geometry provides easy access to hard-to-reach areas in welded assemblies.

• Heavy steel grinding: In steel mills, heavy metal fabrication and boilermaking, this wheel offers high material removal rate while maintaining precise cutting profile. Cubitron 3 reduces burning risks compared to standard alumina wheels.

• Surface preparation for coatings: The 36+ grit creates an optimal anchor profile on metal surfaces before industrial paint or anticorrosion coating application.

• Industrial maintenance and repair: Ideal for maintenance teams performing occasional grinding on industrial equipment, metal structures and piping.

FAQ - Frequently asked questions

What is Cubitron 3 technology versus standard wheels?

3M's Cubitron 3 technology uses precision triangle-shaped ceramic grains that cut metal rather than scraping it. Unlike aluminum oxide grains that dull during use, Cubitron 3 grains fracture in a controlled manner to expose new sharp edges. Result: cutting up to 2 times faster, less heat and significantly longer service life, reducing total cost per ground piece.

Is the Cubitron 3 wheel compatible with all angle grinders?

The SA90007 wheel is compatible with standard angle grinders with 22.23 mm (7/8 in) arbor, maximum 12,250 RPM (ANSI B7.1). Always check your grinder's maximum speed before use. The wheel guard must be in place during all use.

Can the Cubitron 3 wheel be used on stainless steel?

Yes, the Cubitron 3 ceramic grain wheel can be used on stainless steel. For strict stainless applications in food or pharmaceutical environments, use a dedicated new wheel for stainless to avoid ferric cross-contamination. Consult 3M specifications for specific stainless applications.
