3M Cubitron II Depressed Center Grinding Wheel 4.5" x .25" x 5/8-11 Thread

3M Precision-shaped grain engineered to cut faster than competitive ceramic products, offering significant productivity gains
Triangular shaped ceramic grain wears evenly, runs cool, and optimizes mineral breakdown, for extra-long life
Reduces changeouts and downtime in robotic and pressure-assisted applications
Rigid, reinforced resin-bonded wheel slices through almost all materials including stainless steel, mild steel, and aerospace alloys
Wheel must have a maximum operating speed greater than or equal to the maximum speed of the power tool used
Must be used with ANSI-approved guard that fits the size of the wheel
