Most DIYers think about the fastener, but the hole is where the battle is won or lost. This episode builds a practical drilling consumables inventory for Israeli households — covering HSS, cobalt, brad-point, masonry, SDS-plus, and tile bits. We break down which sizes to duplicate, when cheap kits fail, and why an SDS rotary hammer transforms drilling into hard concrete. Plus: how to handle rebar, clear dust properly, and avoid ruining tile in one second.
