did i fry my hammer drill's chuck ?
i have a BOSCH regular chuck hammer drill and have been using it to drill anchor holes in the foundation of my house for dropping the concrete floor. i like to tie wire mesh to 3/8" x 8" anchor bolts that are epoxied into the foundation.
to call this drilling hard-core would be an understatement. the foundation is 100 years old with many pebbles, i am compressing my hole upper body while drilling, making many yoga postures look like laying out on the beach. i depleted three bits through about 100 holes both the flutes as well as the bottom part that goes into the chuck.
what surprised me, however, is that the chuck has suffered a lot of W/T, manifesting itself in being extremely hard to turn with a key. almost as though the worn steel from the bits has caked into it impeding adjustment.
should i just replace the chuck ? i am disappointed that a brand like BOSCH could not take this much abuse.
