Overview
The PORTER-CABLE PCC641LB is a 20 volt battery powered impact tool rated at 4 amps and 2800 RPM. It weighs 3 pounds and measures roughly 9 by 6.25 by 10.75 inches.
At 3 pounds this sits on the lighter end for a 20 volt impact tool, which helps with overhead or one-handed use. The listing covers voltage, amperage, speed and dimensions but says nothing about an included battery or charger, so buyers should check whether this is sold as a bare tool. Torque output is not listed.
- 20 volt battery powered
- 2800 RPM speed
- 3 pound weight
- About 9 x 6.25 x 10.75 inches
Who it's for
Suited to owners already invested in a 20 volt battery platform who need an impact tool for driving fasteners. Less useful to someone who needs a complete kit with battery and charger included, since that is not confirmed here.
Strengths and trade-offs
Drawn from this product's published specifications.
- Light at 3 pounds
- 2800 RPM rated speed
- No torque spec listed
- Battery inclusion not confirmed
Performance notes
At 2800 RPM and 4 amps, this impact tool is built for driving fasteners quickly rather than high torque bolt work, though no torque figure is listed. The 3 pound weight and roughly 9 inch length suit one-handed and overhead use. Run time depends on the battery, which the spec sheet does not confirm as included.
