Raytools BM110 (older): M14, D32 mm nozzles. SKUs start LF-NOZZLE/D and LF-NOZZLE/S. Holder LF-NOZZLE/HOLDER. Same lens size as BS03K.
Raytools BS03K / BS03K-CAT (current new machines): M11, D28 mm nozzles. SKUs start LF-NOZZLE/HS/D and LF-NOZZLE/HS/S. Holder LF-NOZZLE/HOLDER/D28. 28 mm cuts faster and uses less air than 32 mm.
Empower is the company; RayTools is the brand; BS03K-CAT is the series.
One machine already in the market uses a BOCI BLT310 head; it takes the same M11 D28 mm nozzles as BS03K.
LF-NOZZLE SKUs are a box of 10. New machines ship with the full hole-size set so the client can test; not every size is required for every job.
