| End A | Bosch GCM12SD miter saw port (1-1/4 in ID) |
|---|---|
| End B | 1-1/4 in shop-vac hose (approx 1-1/2 cuff in OD, 1-1/4 in ID) |
| Fit type | hose cuff into female socket |
| Reducer needed | none, direct friction fit |
Shop notes
The hose tip measures about 32 mm and the port socket about 32 mm, the same, so the hose tip seats inside the port socket as a friction fit. No reducer is needed for this pairing, so the Bosch GCM12SD miter saw port and the 1-1/4 in shop-vac hose connect directly.
It is a push fit, not a lock. Seat it fully and check it has not crept loose after a few minutes of vibration before you trust it on fine dust.
