THE SAW ADVISOR - MITER SAW DUST CONNECTION WORKSHEET
Source check: October 21, 2026. Print or save this file. No signup.

DOCUMENTED EXAMPLE (NOT A HANDS-ON TEST)
Saw: Bosch GCM12SD
Adapter: Bosch VAC024
Hose class: common 1-1/4-inch or 1-1/2-inch vacuum hose
Decision: both current Bosch product listings support this pairing.
Exclusion: the current GCM12SD listing says VAC002 is not compatible.
Conflict: the 2018 GCM12SD manual, page 19, also names VAC002.
Use the exact version's instructions; ask Bosch if they disagree.
Not established here: measured port/cuff diameters, insertion depth,
fit of an individual third-party hose, airflow or dust exposure control.
