3M Depressed Center Grinding Wheel Type 27

The 3M Depressed Center Grinding Wheel Type 27 is a rigid, resin-bonded grinding wheel for angle grinders. It is built for heavy weld removal and other demanding grinding jobs. The Type 27 depressed center design (also called a raised hub or Type 27 grinding disc) lets the wheel sit at an angle to the work surface. The mounting hub stays clear of the surface during aggressive stock removal.

Key Features:

• Cubitron 3 precision-shaped ceramic grain: The grain is designed to fracture continuously into sharp points. This helps the wheel cut fast, run cooler and wear evenly.
• Heavy-duty performance: Made for heavy weld removal and other heavy-duty grinding on a wide range of materials. It is specially formulated for stainless steel, mild steel and aerospace alloys.
• Long-lasting resin bond: The rigid bond gives a durable wheel that holds up to demanding metal fabrication work.
• Type 27 depressed center: Suited to grinding and weld blending with a standard angle grinder.
• Threaded 5/8-11 arbor: Mounts to angle grinders with a matching threaded spindle.
• ANSI standards: Manufactured to meet ANSI requirements.

Always use the wheel with a proper tool guard. Do not exceed the maximum operating speed marked on the wheel. The product line draws on more than 100 years of 3M abrasives experience. It suits metalworking, fabrication and welding shops that want productive, consistent grinding.
