Bosch Professional SDS Plus-5X Hammer Drill Bit, With 4 Flute, Diameter 6mm & Working Length 100mm, Pack Of 1

At the outset, I am a home user, not having much experience in drilling etc.My house is quite old, and bricks are far stronger, and harder than present day bricks. Since normal bits go in with quite some force in these bricks, I decided to purchase 2 of these bits.They are quite long, one about 100mm, about 4", and the other 140 mm, about 6".They drilled very easily through the hard, strong bricks, and not much force was required.Though quite costly, I think especially good for people who don't want to use much force , or are not in a position to use much force, or are aged, and want to drill on hard material.Haven't tried on concrete so far.
