Overview
Running on a 21 volt battery platform, the TC02 is a 1/2 inch cordless impact wrench listed at 4.1 kilograms (about 9 pounds). It targets users who need power for lug nuts, suspension bolts, and similar high-torque fastening work.
21 volt battery platforms sit toward the higher end of cordless tool voltage, generally trading a heavier pack for longer runtime and more torque. At 4.1 kilograms this tool is noticeably heavier than compact 12 to 18 volt impact wrenches, which matters for overhead or repetitive one-handed use. No torque figure in foot-pounds or newton-meters is given in this listing, so peak output is not confirmed here.

Who it's for
DIY mechanics and light trade users who want a cordless 1/2 inch impact wrench for automotive or equipment work and are not bothered by the extra weight of a 21 volt pack.
Strengths and trade-offs
Drawn from this product's published specifications.
- 21 volt platform for higher sustained torque
- 1/2 inch drive fits standard impact sockets
- Cordless operation for mobile use
- 4.1 kilograms is heavy for one-handed or overhead work
- No torque rating listed in foot-pounds or newton-meters
- Battery and charger inclusion not specified
Performance notes
Higher voltage battery packs typically sustain torque longer before the cell voltage sags, which is the tradeoff for the added 4.1 kilogram weight here. Without a published torque spec, buyers comparing this to other 21 volt impact wrenches should check torque figures separately.
