Product description
BT SLA side-lock holders cover the larger 25, 32 and 40 mm shank selections in the catalog. Available combinations differ between BT30, BT40 and BT50, and body diameters increase with the selected tooling. Review the machine interface, end mill shank and surrounding clearance together before specifying a model for quotation.
Body clearance
Check holder diameter against clamps, pockets and other features surrounding the cut.
Fixed bore matching
Match the tool shank and side-lock arrangement to the selected holder's drawing.
Checking the BT40-SLA40-120 envelope
The BT40-SLA40-120 row lists L = 185.4 mm, D = 90 mm and D1 = 44.45 mm. Use those labeled dimensions with the drawing when checking space around the workpiece and fixture. The “120” in the code and the table’s L = 185.4 mm are not the same value; state which reference points your required length uses.
Start an inquiry with this catalog row. Add the tool-shank drawing, quantity and any clearance limit. Ask for confirmation of the side-lock arrangement and the items included in the quotation.
Specify a bore, not a slash-separated family
The BT40-SLA25/32-100 row groups two shank selections. Identify either 25 mm or 32 mm in the request, then confirm the corresponding body dimensions. A grouped code is not a holder that changes between both bores.
For the smaller catalog shank groups, compare BT SLB side-lock holders. For a different clamping arrangement, see BT ER collet holders and check the tool interface before substituting.

Application scenarios
Typical selection contexts for this series, not customer project claims. Confirm machine compatibility and cutting conditions for your setup.
Large-shank tooling
Holding suitable end mills where the catalog SLA bore sizes are required.
BT production machines
Planning dedicated holders for a confirmed BT machining-center spindle.
Fixture review
Checking the larger holder body's envelope before committing to a setup.
Inspection & order review
Specify the dimensions, tolerances and records your order requires. Acceptance criteria must be agreed for the selected model.
Catalog fields to check
- Ordering code
- L
- D
- D1
Check the drawing reference faces and units. A catalog size alone does not define a tolerance or an inspection method.
Records to request
List any required dimensional report, material document or model identification photograph in your inquiry. Confirm availability and scope in the quotation.
For a drawing-based part, include the drawing revision and identify the critical dimensions. Website photographs are not inspection reports.
Packaging & delivery
Agree the packing method and photo requirements when confirming your order.
Order-specific photo confirmation
No verified shipment photographs for this series are currently published. Include selected-model, protective-packing and outer-label photos in your order requirements.
Discuss packing requirementsPhotos to confirm before dispatch
Use this checklist to agree what should be documented for your selected model.
- Selected bore and interface code documented
- Retaining hardware checked against the order
- Large holder bodies separated from exposed tapers
Stock, dispatch date and shipping method are confirmed with the quotation. Website images are not live inventory evidence.

Models and specificationsIs every listed bore offered in BT30?
No. The BT30 row lists SLA25. Check the exact interface row rather than extending the full family range to every size.
Can I replace an ER holder with this holder without further checks?
No. Verify the tool shank, retention method, reach and clearance because the clamping arrangements differ.
Does a larger shank mean a published heavy-cutting rating?
No cutting-load rating is supplied in this catalog. The complete machine, tool and holder setup requires review.
What should accompany an inquiry for a long version?
Provide the target gauge or overall length definition, spindle interface, shank drawing and clearance constraints.
