Sorry if this is a basic question, how do you choose the right drill bit size, and where do reamers actually come in? Sorry if this is a simple question, I'm still learning basic drilling and fitting work, so I might be overthinking this. I've been reading about how to choose the right drill bit size, and most guides say to match the bit size to the solid core of the screw and not the threads. That makes sense and it already helped me avoid a few mistakes. I also came across the three common types of drill bits. Masonry bits for concrete, brick and stone. Twist bits for general wood, plastic and light metal use. And woodboring bits for cleaner holes in wood projects. But what I'm still confused about is where reamers actually fit into all of this. From what I understand, reamers are used after drilling to slightly enlarge or smooth a hole to a more precise diameter. But I'm not sure when that becomes necessary in real DIY work versus industrial or machining setups.…
