Battery backup is good I drilled 2 holes on each end for Curtain hangers and did that for 5 windows and it still has more than half battery

If you want high torque go for impact driver but you will not get clutch with that

20602 is better it comes in a box while 20608 comes in a bag, 20602 is compact and has high impact rate and you will get some drill bits in the box

Just go for the 20605 with 70nm. Dont mind compactness of 20602. Cordless drills are small already in general so get the highest torque model and pair with 6ah or higher battery and always have a 2ah battery for light task.

Yes 20605 is better

Which is best for concrete

@@gshankargurusamy7612 20605 pair with 7.5 ingco battery

I have not used it continuously but I think it can go for 3-4 hours on single charge

Yes 👍

Thank You
