Product details
BT SCA adapters connect suitable side milling cutters to the listed BT spindle interfaces. The series includes metric and selected inch pilot options, with dimensions grouped by ordering family. A cutter's bore, drive details and operating width should be reviewed together so the selected adapter suits the intended slot or side-milling arrangement.
Metric and inch variants
Keep the pilot designation in its original units when selecting an ordering family.

Models and specificationsWill every side cutter fit an SCA adapter?
No. Match the cutter bore, drive geometry, width and fastening arrangement to the selected adapter.
Can the cutter outside diameter identify the pilot size?
No. Outside diameter and mounting bore are separate dimensions.
Are the related HJS cutters confirmed matches?
They are relevant cutters to compare, not a prevalidated assembly list. Confirm the complete mounting drawing.
Why should I check the L1 drawing?
The source uses grouped codes and a Catalog L1 column. Confirm the dimension's reference faces before specifying reach.
