Overview
The CRAFTSMAN CMCK401D2 is a 20 volt cordless combo kit built around a 2 amp hour battery system, with a motor rated up to 4200 RPM. The full kit weighs 16.9 pounds, putting it in the range of a multi tool set rather than a single power tool.
CMCK401D2 combo kits pair several 20V MAX tools on one battery platform, which is the main appeal over buying separate corded tools: one charger and one battery size across the kit. The listing here only confirms battery voltage, amperage and top speed, not which individual tools are included, so check the box contents before buying if a specific tool is the reason for the purchase. This entry was filed under Specialties, but the spec sheet points clearly to a cordless combo kit.
- 20 volt cordless battery system
- 2 amp hour battery capacity
- Motor speed up to 4200 RPM
- 16.9 pound total kit weight
Who it's for
Fits someone building out a first cordless tool set on one battery platform, home renovators and DIYers who want several tools sharing chargers and batteries. It suits kit buyers more than someone shopping for one specific tool, since the exact tool lineup is not detailed in this data.
Strengths and trade-offs
Drawn from this product's published specifications.
- Shared 20V battery platform across the kit
- 16.9 pound total kit weight keeps it manageable
- Motor speed up to 4200 RPM for general fastening work
- Exact tools included are not detailed in the spec data
- 2 amp hour battery gives shorter runtime than larger packs
- No reviews yet to confirm long term reliability
Performance notes
The 4200 RPM top speed points to a drill or driver style motor tuned for general fastening and drilling rather than heavy demolition. Running on a 20 volt, 2 amp hour battery keeps the kit's individual tools compact, at the cost of shorter runtime per charge than a higher capacity battery would give.
