Dremel 953 tapered grinding stone
Tapered aluminum oxide head with a documented 1/4-inch working diameter.

How to choose
The tapered profile lets you compare access in a corner with a broader stone. Confirm that the model is the two-stone package if you need a spare.

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 would make me choose the wider 932 instead?
The 932 has a larger cylindrical working face. Compare it for an exposed edge with space for the head and keep the tapered 953 in mind when clearance tightens toward the end.
