Symptoms Compound feels dry, dusty or inactive on a small tool.The tool does not transfer compound smoothly into the contact zone.
Likely causes Low surface speed and low temperature may prevent the compound binder from becoming sufficiently mobile.Too much compound or a dirty tool can make the small-tool contact even less stable.
Checks Check tool diameter and rpm.Inspect whether the tool is clean and lightly charged.Compare behaviour with a standard wheel if possible.
Recommended fixes Use less compound.Clean the tool.Check rpm and diameter.Consider low-temperature LUXI compounds when the tool remains cool.
Prevention Develop small-tool routes separately from standard wheel routes.Record rpm, diameter and compound behaviour.
