Product description

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.

Side cutter connection

Start from the cutter's mounting bore and drive geometry rather than its outer diameter.

Metric and inch variants

Keep the pilot designation in its original units when selecting an ordering family.

Dimension verification

The source labels a column Catalog L1; confirm its drawing reference before comparing reach.

Specifications & model range

Dimensions are in millimeters. Catalog L1 entries are individual values grouped by ordering family, not continuous length ranges. The code suffix and the table's L1 entry are shown separately as in the source; confirm their meaning and the exact pilot/length pairing on the selected drawing.

Ranges and slash-separated values describe catalog families, not every possible combination. Confirm the complete model and drawing before ordering.

Application scenarios

Typical selection contexts for this series, not customer project claims. Confirm machine compatibility and cutting conditions for your setup.

Slot machining

Mounting a matched side cutter for a planned slot geometry.

Side-face operations

Checking cutter width and adapter envelope for side milling setups.

Cutter replacement programs

Matching metric or inch mounting arrangements already used on BT machines.

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 family
  • Catalog L1
  • D2

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.

Photos to confirm before dispatch

Use this checklist to agree what should be documented for your selected model.

  • Adapter pilot and code recorded
  • Drive features and mating faces protected
  • Any ordered spacers or fasteners itemized

Stock, dispatch date and shipping method are confirmed with the quotation. Website images are not live inventory evidence.

Product FAQ

Selection questions for BT SCA Side Cutter Adapters.

Request a quote
Will 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.
