Overview
A 20V cordless impact tool listed under the model number DC5129-AS-New. At 5.7 pounds it sits on the heavier side for a handheld impact, and the listing gives no torque, anvil size or drive type to go on.
Voltage and weight are the only two figures attached to this listing, which is unusual for a tool in this category. Shoppers who already run other 20V-platform tools should confirm battery compatibility directly with the seller, since no shared battery system is named here. Torque output, chuck or anvil size and drive size are all absent from the spec sheet.

Who it's for
Best suited to someone who already has a battery and charger from a matching 20V line and just needs an impact tool to round it out. Anyone comparing torque ratings or drive sizes across brands will not find that data on this listing and should look elsewhere or ask the seller directly.
Strengths and trade-offs
Drawn from this product's published specifications.
- Runs on a common 20V battery platform
- Weight suggests a substantial internal build
- No torque rating published
- Drive or anvil size not stated
- Included accessories not listed
Performance notes
Impact tools of this type deliver rotational force in rapid bursts rather than steady torque, which is what lets them drive long fasteners without stalling. At 5.7 pounds the DC5129-AS-New is on the heavier end for one-handed use, which can add fatigue during overhead or extended work but also usually signals a more substantial internal gear set.
