I must agree with skelton
i had a makita 110v and it was fine for 6 to 10mm anchor holes.
anything bigger the torque limiter clutch kicked in too early and every holesaw and larger diameter hole became a task n a half
gave it to my brother and bought a 36v bosch
used it every day for four years and dropped it last year of a pair of steps and broke it.it was a good drill alright.
im using a metabo 28v Sds just now which is lighter than the Bosch and has much the same performance
over the years for corded Sds I rate Bosch ,hilti and Metabo.
bosch invented the special drilling system and licences it to everyone else
