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 is the main difference from the 9903HP for the same groove?
The 9903HP adds a coating while retaining the round-end family profile. Compare the two for the same material and access before choosing by price or coating.
