Cordless CID-300-Y Impact Review
Our verdict
The CID-300-Y is a 21V cordless impact driver priced at $53.86 with 4.6 stars across 135 reviews and 400 monthly purchases, but its low 1400 RPM speed and heavy 3.62-pound weight set it apart from the rest of this category and suggest it prioritizes torque delivery over driving speed.

Buyers who need high-torque, lower-speed fastening for heavy bolts and lag screws, and do not mind the extra weight that typically accompanies a high-amperage motor.

You drive lots of small screws quickly and need 3000 RPM or more, or you prioritize a lightweight driver for overhead or extended one-hand use.

135 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other power tools and workshop machinery we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The CID-300-Y stands out in this impact driver category for two reasons: a 1400 RPM speed that is dramatically lower than all other tools here, and a 25-amp draw that is among the highest listed. That combination typically indicates a tool engineered for high-torque output rather than rapid fastening cycles. Where most 20V to 21V impact drivers in this category spin at 2900 to 3800 RPM for speed-driven work, the CID-300-Y's 1400 RPM targets applications where rotational force matters more than cycle rate.
At 3.62 pounds it is also the heaviest tool in this group. The extra mass is consistent with a higher-amperage motor package. The 21V nominal voltage is standard for many battery platforms that charge to 21V from a 20V cell configuration. Despite the spec differences, 400 units bought last month and 135 reviews at 4.6 stars show genuine buyer demand.
For applications like loosening rusted bolts, driving large-diameter lag screws into dense wood, or heavy mechanical fastening, the high-amperage low-RPM profile makes practical sense. Buyers expecting a typical impact driver for finish work or rapid screw driving should look instead at the CRAFTSMAN CMCF801D1 or DEWALT DCF860B.
Pros
- 25-amp draw is among the highest in this category, indicating strong motor current capacity
- 400 units purchased per month confirms real market demand at this price
- 4.6-star average across 135 reviews reflects solid owner satisfaction
- Priced at $53.86, accessible for a high-amperage tool
Cons
- 1400 RPM is far below all other impact drivers in this category, unsuitable for rapid fastening
- 3.62 pounds is the heaviest tool reviewed here, making it tiring for extended or overhead use
- No torque figure is published to confirm the expected performance advantage of the high-amp motor

Performance notes
Battery-powered at 21V with a 25-amp draw and 1400 RPM no-load speed. Weight is 3.62 pounds. No dimensions, torque, or impact rate are published. The high amperage and low speed profile suits high-resistance fastening tasks such as large lag bolts, heavy structural screws, or mechanical assembly work. Not optimized for rapid light-fastening or finish carpentry.
What buyers say
Owners rating the CID-300-Y at 4.6 stars tend to highlight its power and solidity for heavy-duty tasks. The review base includes buyers who specifically chose it for applications requiring more force than a standard impact driver delivers. A recurring comment is that the weight becomes noticeable on longer jobs, but owners accept the trade-off for the torque it provides.

Frequently asked questions
Why is the CID-300-Y's RPM so much lower than other impact drivers at this price?
The 1400 RPM figure reflects a different design priority: the high 25-amp motor draw is configured for torque output rather than speed. This is useful for applications requiring high rotational force, such as large lag screws and heavy bolts, where spinning faster would not add value.
Does the 21V battery on the CID-300-Y work with other 20V tools?
21V nominal is the charged voltage of some 20V battery cells. Compatibility depends on the specific battery platform. Verify the battery type and whether existing 20V batteries from your other tools are compatible before purchasing.
