Product details
The BT SLB series provides side-lock end mill holders for the smaller shank groups listed in the company catalog. BT30, BT40 and BT50 versions have different body diameters and overall lengths. Choose the exact shank bore and machine interface, and check the tool's side-lock geometry before confirming the holder code.
Side-lock connection
The tool shank must suit the holder's retention arrangement; verify the tool drawing.
Length interpretation
Use the table's L dimension as labeled; do not substitute it for a different gauge-length definition.
Specifications & model range
Dimensions are in millimeters unless otherwise stated. Confirm the final drawing before ordering.

Models and specificationsHow does SLB differ from the SLA page?
This catalog groups SLB around smaller shanks, while the SLA page lists 25, 32 and 40 mm tooling.
Can I clamp an arbitrary round shank?
Confirm the tool's shank and retention geometry with the holder drawing. Diameter alone is not sufficient.
Is L in the table the gauge length?
The source labels that column L. Confirm the dimensional drawing instead of treating it as an interchangeable length definition.
Why do some ordering codes show SL rather than SLB?
The source uses those code forms within the SLB series table. Submit the full source code for drawing confirmation.
