Product details
BT FMB face mill arbors use metric pilot sizes to mount suitable face or shell milling cutters. The catalog spans several BT interfaces and length options, but not every pilot and length combination is listed for each interface. Confirm the cutter's mounting bore, drive features and fastening arrangement before selecting the complete arbor code.
Interface-specific lengths
Use the available L1 options for the selected BT and FMB family.
Cutter-side geometry
Check drive and fastening details against the cutter drawing before confirming an assembly.

Models and specificationsWhat is the distinction between FMB and FMA in this catalog?
FMB is organized around metric pilots. FMA lists inch-based pilot dimensions; confirm the cutter's actual mounting specification.
Can I select the arbor using the face mill's outer diameter?
No. Use the mounting bore, drive features and fastening arrangement as well as the cutter's envelope.
Are the longest catalog lengths offered for every pilot?
No. Length options belong to specific rows and must be confirmed for the required code.
Are the related shell cutters guaranteed to fit?
No. They are related tooling to compare; pilot units, dimensions, drive and fixing details must all match.
