The CDL1802D was an 18V cordless drill/driver from Ryobi’s earlier ONE+ generation — the blue tools, before the current green-and-black styling and before brushless motors appeared in the range.
The tool is discontinued. The platform is not, and that is the useful part.
ONE+ compatibility is the thing to know
Ryobi’s promise on ONE+ is that the battery mount has not changed since 1996, and it holds. A current lithium ONE+ pack will run a CDL1802D, and a current ONE+ tool will run on whatever packs you have.
So if your drill still works, buying a modern high-capacity lithium battery is the cheapest way to make it feel new — particularly if it originally shipped with NiCd packs, which will be long dead.
What eventually kills these is the chuck and the clutch. A chuck that will not grip a bit squarely, or a clutch that slips at every setting, is not economically repairable on a drill at this price point.
What replaces it
The Ryobi ONE+ HP brushless drill kit, linked below, is the current equivalent, and the same batteries move straight across.
The brushless motor is the real upgrade over the tool you are replacing: more torque from the same pack, less heat, and a motor with no brushes to wear. If you are buying anyway, do not buy the brushed version to save a little.
