Start by matching your task to the drill bits orange type (wood, metal, or masonry) and choose a kit with the sizes you’ll need. Check the shank size and whether the kit is designed for cordless screwdrivers like the 4.8V model or a hand drill. Consider the material and coating (for example, HSS for general use, cobalt or carbide for tougher work) and the total pieces in the set (such as a 45 PCs kit) to ensure you have common sizes. Color helps identify orange-branded sets at a glance, but always verify the exact contents in the description.
