So I purchased my combi drill and impact a couple months back but still need to fill up the accessory compartments in the carry case, so far I've picked up a Weisser pivoting bit holder, a wera set of bits that contains all the normal bits, pozi philips, slot, hex etc. I've also got the trend flip and drill and hinge centering bits. So what does everyone else keep, I'm hoping to purchase a few more bit sets myself, hss bit, wood up to 10mm, a right angle Attachment etc. Any brands you's would recommend?
