Dremel 426 reinforced screw-mount wheel
426 is a 1-1/4-inch fiberglass-reinforced cut-off wheel for the documented screw mandrel.

How to choose
Choose it if your tool is already set up with the specified 402 holder and the wheel matches the material. Confirm the center mounting system even when another wheel has a similar diameter.
Compatibility and limits

Care
Before mounting the accessory, check its speed rating against the tool and use the holder specified for its shank or mandrel. Refer to the exact model instructions for the workpiece.
Questions before buying
What makes the 426 different from the 420 if I already have the 402?
The 426 has a larger diameter and fiberglass reinforcement. Check the available space around the cut before choosing it over the smaller 420.
