Tips

Ensure the set screw is properly torqued against the Weldon flat on the tool shank to prevent slippage. For optimal balance at high speeds, use tools with matching balance quality. Verify the machine taper selection (e.g., SK40, HSK63A, BT40) when ordering, as it is not included in this model.
