Models and specificationsIs this the same item as a BT drill chuck arbor?
No. The catalog describes this series as an integrated direct holder; the arbor page covers a separate mounting component.
Can I infer the full clamping range from SPU13?
Request the confirmed capacity for the selected model. This table lists the size code but not a complete minimum-to-maximum range.
Are the listed lengths interchangeable within each BT size?
Confirm the exact SPU and length combination because grouped table ranges do not define every possible combination.
Is a maximum speed published?
No maximum speed is established in the supplied catalog data; confirm the intended operating requirements during quotation.
